refs: rename git_reference__set_name to git_reference__realloc
As git_reference__name will reallocate storage to account for longer
names (it's actually allocator-dependent), it will cause all existing
pointers to the old object to become dangling, as they now point to
freed memory.
Fix the issue by renaming to a more descriptive name, and pass a pointer
to the actual reference that can safely be invalidated if the realloc
succeeds.

refdb_fs: properly parse corrupted reflogs
In previous versions, libgit2 could be coerced into writing reflog
messages with embedded newlines into the reflog by using
`git_stash_save` with a message containing newlines. While the root
cause is fixed now, it was noticed that upstream git is in fact able to
read such corrupted reflog messages just fine.
Make the reflog parser more lenient in order to just skip over
malformatted reflog lines to bring us in line with git. This requires us
to change an existing test that verified that we do indeed _fail_ to
parse such logs.

reflog: allow adding entries with newlines in their message
Currently, the reflog disallows any entries that have a message with
newlines, as that would effectively break the reflog format, which may
contain a single line per entry, only. Upstream git behaves a bit
differently, though, especially when considering stashes: instead of
rejecting any reflog entry with newlines, git will simply replace
newlines with spaces. E.g. executing 'git stash push -m "foo\nbar"' will
create a reflog entry with "foo bar" as entry message.
This commit adjusts our own logic to stop rejecting commit messages with
newlines. Previously, this logic was part of `git_reflog_append`, only.
There is a second place though where we add reflog entries, which is the
serialization code in the filesystem refdb. As it didn't contain any
sanity checks whatsoever, the refdb would have been perfectly happy to
write malformatted reflog entries to the disk. This is being fixed with
the same logic as for the reflog itself.

refs: fix locks getting forcibly removed
The flag GIT_FILEBUF_FORCE currently does two things:
1. It will cause the filebuf to create non-existing leading
directories for the file that is about to be written.
2. It will forcibly remove any pre-existing locks.
While most call sites actually do want (1), they do not want to
remove pre-existing locks, as that renders the locking mechanisms
effectively useless.
Introduce a new flag `GIT_FILEBUF_CREATE_LEADING_DIRS` to
separate both behaviours cleanly from each other and convert
callers to use it instead of `GIT_FILEBUF_FORCE` to have them
honor locked files correctly.
As this conversion removes all current users of `GIT_FILEBUF_FORCE`,
this commit removes the flag altogether.

fileops: rename to "futils.h" to match function signatures

global: convert trivial `fnmatch` users to use `wildcard`
Upstream git.git has converted its codebase to use wildcard in
favor of fnmatch in commit 70a8fc999d (stop using fnmatch (either
native or compat), 2014-02-15). To keep our own regex-matching in
line with what git does, convert all trivial instances of
`fnmatch` usage to use `wildcard`, instead. Trivial usage is
defined to be use of `fnmatch` with either no flags or flags that
have a 1:1 equivalent in wildmatch (PATHNAME, IGNORECASE).

refdb_fs: fix race when migrating loose to packed refs in iteration
Right now, we first load the packed refs cache and only afterwards load the
loose references. This is susceptible to a race when the loose ref is being
migrated to a packed cache by e.g. git-pack-refs(1):
libgit2 git-pack-refs
1. We load the packed ref, which
does not yet have the migrated
reference.
2. git-pack-refs updates the packed ref
file to have the migrated ref.
3. git-pack-refs deletes the old loose
ref.
4. We look up the loose ref.
So we now do not find the reference at all and will never iterate over it.
Fix the issue by reversing the order: instead of first loading the packed refs,
we will now look up the loose reference first. If it has already been deleted,
then it must already be present in the packed-refs by definition, as git.git
will only delete the reference after updating the packed refs file.

refdb_fs: remove ordering dependency on loose/packed refs loading
Right now, loading loose refs has the side-effect of setting the
`PACKREF_SHADOWED` flag for references that exist both in the loose and the
packed refs. Because of this, we are force do first look up packed refs and only
afterwards loading the packed refs. This is susceptible to a race, though, when
refs are being repacked: when first loading the packed cache, then it may not
yet have the migrated loose ref. But when now trying to look up the loose
reference afterwards, then it may already have been migrated. Thus, we would
fail to find this reference in this scenario.
Remove this ordering dependency to allow fixing the above race. Instead of
setting the flag when loading loose refs, we will now instead set it lazily when
iterating over the loose refs. This even has the added benefit of not requiring
us to lock the packed refs cache, as we already have an owned copy of it.

refdb_fs: do not lazily copy packed ref cache
When creating a new iterator, we eagerly load loose refs but only lazily create
a copy of packed refs. The lazy load only happens as soon as we have iterated
over all loose refs, opening up a potentially wide window for races. This
may lead to an inconsistent view e.g. when the caller decides to reload packed
references somewhen between iterating the loose refs, which is unexpected.
Fix the issue by eagerly copying the sorted cache. Note that right now, we are
heavily dependent on ordering here: we first need to reload packed refs, then we
have to load loose refs and only as a last step are we allowed to copy the
cache. This is because loading loose refs has the side-effect of setting the
`PACKED_SHADOWED` flag in the packed refs cache, which we require to avoid
outputting packed refs that already exist as loose refs.

refdb_fs: fix potential race with ref repacking in `exists` callback
When repacking references, git.git will first update the packed refs and only
afterwards delete any existing loose references that have now been moved to the
new packed refs file. Due to this, there is a potential for racing if one first
reads the packfile (which has not been updated yet) and only then trying to read
the loose reference (which has just been deleted). In this case, one will
incorrectly fail to lookup the reference and it will be reported as missing.
Naturally, this is exactly what we've been doing in `refdb_fs_backend__exists`.
Fix the race by reversing the lookup: we will now first check if the loose
reference exists and only afterwards refresh the packed file.

refdb_fs: refactor error handling in `refdb_reflog_fs__delete`
The function `refdb_reflog_fs__delete` uses the `if (!error && foobar())`
pattern of checking, where error conditions are being checked by following calls
to different code. This does not match our current style, where the call-site of
a function is usually directly responsible for checking the return value.
Convert the function to use `if ((error = foobar()) < 0) goto out;` style. Note
that this changes the code flow a bit: previously, we were always trying to
delete empty reference hierarchies even if deleting the reflog entry has failed.
This wasn't much of a problem -- if deletion failed, the hierarchy will still
contain at least one file and thus the function call was an expensive no-op.
Now, we will only perform this deletion if we have successfully removed the
reflog.

refdb_fs: test whether the base directory exists when globbing
This commit fixes a regression introduced by
20a2b02d9a1bcb4825ec49605146223c565dcacf
The commit introduced an optimization for finding references using a
glob: rather than iterating over all references and matching each one
against the glob, we would iterate only over references within the
directory common to all possible references which may match against the
glob.
However, contrary to the `ref/` directory, which was the previous entry
point for the iteration, this directory may not exist. In this case, the
optimization causes an error (`ENOENT`) rather than the iterator simply
yielding no references.
This patch fixes the regression by checkign for this specific case.

Make sure to always include "common.h" first
Next to including several files, our "common.h" header also declares
various macros which are then used throughout the project. As such, we
have to make sure to always include this file first in all
implementation files. Otherwise, we might encounter problems or even
silent behavioural differences due to macros or defines not being
defined as they should be. So in fact, our header and implementation
files should make sure to always include "common.h" first.
This commit does so by establishing a common include pattern. Header
files inside of "src" will now always include "common.h" as its first
other file, separated by a newline from all the other includes to make
it stand out as special. There are two cases for the implementation
files. If they do have a matching header file, they will always include
this one first, leading to "common.h" being transitively included as
first file. If they do not have a matching header file, they instead
include "common.h" as first file themselves.
This fixes the outlined problems and will become our standard practice
for header and source files inside of the "src/" from now on.

settings: rename `GIT_OPT_ENABLE_SYNCHRONOUS_OBJECT_CREATION`
Initially, the setting has been solely used to enable the use of
`fsync()` when creating objects. Since then, the use has been extended
to also cover references and index files. As the option is not yet part
of any release, we can still correct this by renaming the option to
something more sensible, indicating not only correlation to objects.
This commit renames the option to `GIT_OPT_ENABLE_FSYNC_GITDIR`. We also
move the variable from the object to repository source code.

refdb: create references in commondir
References for a repository are usually created inside of its gitdir.
When using worktrees, though, these references are not to be created
inside the worktree gitdir, but instead inside the gitdir of its parent
repository, which is the commondir. Like this, branches will still be
available after the worktree itself has been deleted.
The filesystem refdb currently still creates new references inside of
the gitdir. Fix this and have it create references in commondir.

refdb: catch additional per-worktree refs
The upstream git.git project currently identifies all references inside
of `refs/bisect/` as well as `HEAD` as per-worktree references. This is
already incorrect and is currently being fixed by an in-flight topic
[1]. The new behavior will be to match all pseudo-references outside of
the `refs/` hierarchy as well as `refs/bisect/`.
Our current behavior is to mark a selection of pseudo-references as
per-worktree, only. This matches more pseudo-references than current
git, but forgets about `refs/bisect/`. Adjust behavior to match the
in-flight topic, that is classify the following references as
per-worktree:
- everything outside of `refs/`
- everything inside of `refs/bisect/`

repository: rename `path_repository` and `path_gitlink`
The `path_repository` variable is actually confusing to think
about, as it is not always clear what the repository actually is.
It may either be the path to the folder containing worktree and
.git directory, the path to .git itself, a worktree or something
entirely different. Actually, the intent of the variable is to
hold the path to the gitdir, which is either the .git directory
or the bare repository.
Rename the variable to `gitdir` to avoid confusion. While at it,
also rename `path_gitlink` to `gitlink` to improve consistency.

Fix this problem by renaming the variable to `gitpath`,
clarifying that it acutally points to the `.git` directory of the
repository, in contrast to the commonpath directory, which points
to the directory containing shared objects like references and
the object store.

There might be a few threads or processes working with references
concurrently, so fortify the code to ignore errors which come from
concurrent access which do not stop us from continuing the work.
This includes ignoring an unlinking error. Either someone else removed
it or we leave the file around. In the former case the job is done, and
in the latter case, the ref is still in a valid state.

refdb: make ref deletion after pack safer
In order not to undo concurrent modifications to references, we must
make sure that we only delete a loose reference if it still has the same
value as when we packed it.
This means we need to lock it and then compare the value with the one we
put in the packed file.

refdb_fs: fail if refcache returns NULL pointer
We usually check entries returned by `git_sortedcache_entry` for
NULL pointers. As we have a write lock in `packed_write`, though,
it really should not happen that the function returns NULL.
Assert that ref is not NULL to silence a Coverity warning.

refdb_fs: remove unnecessary check for NULL
The fail-label of `reflog_parse` explicitly checks the entry
poitner for NULL before freeing it. When we jump to the label the
variable has to be set to a non-NULL and valid pointer though: if
the allocation fails we immediately return with an error code and
if the loop was not entered we return with a success code,
withouth executing the label's code.
Remove the useless NULL-check to silence Coverity.

index: allow read of index w/ illegal entries
Allow `git_index_read` to handle reading existing indexes with
illegal entries. Allow the low-level `git_index_add` to add
properly formed `git_index_entry`s even if they contain paths
that would be illegal for the current filesystem (eg, `AUX`).
Continue to disallow `git_index_add_bypath` from adding entries
that are illegal universally illegal (eg, `.git`, `foo/../bar`).

Prevent segfault when parsing a reflog with oid parse error
Using calloc instead of malloc because the parse error will lead to an immediate free of committer (and its properties, which can segfault on free if undefined - test_refs_reflog_reflog__reading_a_reflog_with_invalid_format_returns_error segfaulted before the fix).

git_futils_mkdir_*: make a relative-to-base mkdir
Untangle git_futils_mkdir from git_futils_mkdir_ext - the latter
assumes that we own everything beneath the base, as if it were
being called with a base of the repository or working directory,
and is tailored towards checkout and ensuring that there is no
bogosity beneath the base that must be cleaned up.
This is (at best) slow and (at worst) unsafe in the larger context
of a filesystem where we do not own things and cannot do things like
unlink symlinks that are in our way.

refdb: delete a ref's reflog upon deletion
Removing a reflog upon ref deletion is something which only some
backends might wish to do. Backends which are database-backed may wish
to archive a reflog, log-based ones may not need to do anything.

refdb: use the same id for old and new when renaming a reference
When we rename a reference, we want the old and new ids to be the same
one (as we did not change it). The normal code path looks up the old id
from the current value of the brtanch, but by the time we look it up, it
does not exist anymore and thus we write a zero id.
Pass the old id explicitly instead.

checkout: disallow bad paths on win32
Disallow:
1. paths with trailing dot
2. paths with trailing space
3. paths with trailing colon
4. paths that are 8.3 short names of .git folders ("GIT~1")
5. paths that are reserved path names (COM1, LPT1, etc).
6. paths with reserved DOS characters (colons, asterisks, etc)
These paths would (without \\?\ syntax) be elided to other paths - for
example, ".git." would be written as ".git". As a result, writing these
paths literally (using \\?\ syntax) makes them hard to operate with from
the shell, Windows Explorer or other tools. Disallow these.

Introduce reference transactions
A transaction allows you to lock multiple references and set up changes
for them before applying the changes all at once (or as close as the
backend supports).
This can be used for replication purposes, or for making sure some
operations run when the reference is locked and thus cannot be changed.

reflog: more comprehensive HEAD tests
The existing ones lack checking zeroed ids when switching back from an
unborn branch as well as what happens when detaching.
The reflog appending function mistakenly wrote zeros when dealing with a
detached HEAD. This explicitly checks for those situations and fixes
them.

refs: append to the HEAD reflog when updating the current branch
When we update the current branch, we must also append to HEAD's reflog

default cases.
