tree-wide: do not compile deprecated functions with hard deprecation
When compiling libgit2 with -DDEPRECATE_HARD, we add a preprocessor
definition `GIT_DEPRECATE_HARD` which causes the "git2/deprecated.h"
header to be empty. As a result, no function declarations are made
available to callers, but the implementations are still available to
link against. This has the problem that function declarations also
aren't visible to the implementations, meaning that the symbol's
visibility will not be set up correctly. As a result, the resulting
library may not expose those deprecated symbols at all on some platforms
and thus cause linking errors.
Fix the issue by conditionally compiling deprecated functions, only.
While it becomes impossible to link against such a library in case one
uses deprecated functions, distributors of libgit2 aren't expected to
pass -DDEPRECATE_HARD anyway. Instead, users of libgit2 should manually
define GIT_DEPRECATE_HARD to hide deprecated functions. Using "real"
hard deprecation still makes sense in the context of CI to test we don't
use deprecated symbols ourselves and in case a dependant uses libgit2 in
a vendored way and knows it won't ever use any of the deprecated symbols
anyway.

merge: cache negative cache results for similarity metrics
When computing renames, we cache the hash signatures for each of the
potentially conflicting entries so that we do not need to repeatedly
read the file and can at least halfway efficiently determine whether two
files are similar enough to be deemed a rename. In order to make the
hash signatures meaningful, we require at least four lines of data to be
present, resulting in at least four different hashes that can be
compared. Files that are deemed too small are not cached at all and
will thus be repeatedly re-hashed, which is usually not a huge issue.
The issue with above heuristic is in case a file does _not_ have at
least four lines, where a line is anything separated by a consecutive
run of "\n" or "\0" characters. For example "a\nb" is two lines, but
"a\0\0b" is also just two lines. Taken to the extreme, a file that has
megabytes of consecutive space- or NUL-only may also be deemed as too
small and thus not get cached. As a result, we will repeatedly load its
blob, calculate its hash signature just to finally throw it away as we
notice it's not of any value. When you've got a comparitively big file
that you compare against a big set of potentially renamed files, then
the cost simply expodes.
The issue can be trivially fixed by introducing negative cache entries.
Whenever we determine that a given blob does not have a meaningful
representation via a hash signature, we store this negative cache marker
and will from then on not hash it again, but also ignore it as a
potential rename target. This should help the "normal" case already
where you have a lot of small files as rename candidates, but in the
above scenario it's savings are extraordinarily high.
To verify we do not hit the issue anymore with described solution, this
commit adds a test that uses the exact same setup described above with
one 50 megabyte blob of '\0' characters and 1000 other files that get
renamed. Without the negative cache:
$ time ./libgit2_clar -smerge::trees::renames::cache_recomputation >/dev/null
real 11m48.377s
user 11m11.576s
sys 0m35.187s
And with the negative cache:
$ time ./libgit2_clar -smerge::trees::renames::cache_recomputation >/dev/null
real 0m1.972s
user 0m1.851s
sys 0m0.118s
So this represents a ~350-fold performance improvement, but it obviously
depends on how many files you have and how big the blob is. The test
number were chosen in a way that one will immediately notice as soon as
the bug resurfaces.

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.

Rename opt init functions to `options_init`
In libgit2 nomenclature, when we need to verb a direct object, we name
a function `git_directobject_verb`. Thus, if we need to init an options
structure named `git_foo_options`, then the name of the function that
does that should be `git_foo_options_init`.
The previous names of `git_foo_init_options` is close - it _sounds_ as
if it's initializing the options of a `foo`, but in fact
`git_foo_options` is its own noun that should be respected.
Deprecate the old names; they'll now call directly to the new ones.

oidmap: introduce high-level setter for key/value pairs
Currently, one would use either `git_oidmap_insert` to insert key/value pairs
into a map or `git_oidmap_put` to insert a key only. These function have
historically been macros, which is why their syntax is kind of weird: instead of
returning an error code directly, they instead have to be passed a pointer to
where the return value shall be stored. This does not match libgit2's common
idiom of directly returning error codes.Furthermore, `git_oidmap_put` is tightly
coupled with implementation details of the map as it exposes the index of
inserted entries.
Introduce a new function `git_oidmap_set`, which takes as parameters the map,
key and value and directly returns an error code. Convert all trivial callers of
`git_oidmap_insert` and `git_oidmap_put` to make use of it.

oidmap: introduce high-level getter for values
The current way of looking up an entry from a map is tightly coupled with the
map implementation, as one first has to look up the index of the key and then
retrieve the associated value by using the index. As a caller, you usually do
not care about any indices at all, though, so this is more complicated than
really necessary. Furthermore, it invites for errors to happen if the correct
error checking sequence is not being followed.
Introduce a new high-level function `git_oidmap_get` that takes a map and a key
and returns a pointer to the associated value if such a key exists. Otherwise,
a `NULL` pointer is returned. Adjust all callers that can trivially be
converted.

maps: use uniform lifecycle management functions
Currently, the lifecycle functions for maps (allocation, deallocation, resize)
are not named in a uniform way and do not have a uniform function signature.
Rename the functions to fix that, and stick to libgit2's naming scheme of saying
`git_foo_new`. This results in the following new interface for allocation:
- `int git_<t>map_new(git_<t>map **out)` to allocate a new map, returning an
error code if we ran out of memory
- `void git_<t>map_free(git_<t>map *map)` to free a map
- `void git_<t>map_clear(git<t>map *map)` to remove all entries from a map
This commit also fixes all existing callers.

merge: virtual commit should be last argument to merge-base
Our virtual commit must be the last argument to merge-base: since our
algorithm pushes _both_ parents of the virtual commit, it needs to be
the last argument, since merge-base:
> Given three commits A, B and C, git merge-base A B C will compute the
> merge base between A and a hypothetical commit M
We want to calculate the merge base between the actual commit ("two")
and the virtual commit ("one") - since one actually pushes its parents
to the merge-base calculation, we need to calculate the merge base of
"two" and the parents of one.

merge: reverse merge bases for recursive merge
When the commits being merged have multiple merge bases, reverse the
order when creating the virtual merge base. This is for compatibility
with git's merge-recursive algorithm, and ensures that we build
identical trees.
Git does this to try to use older merge bases first. Per 8918b0c:
> It seems to be the only sane way to do it: when a two-head merge is
> done, and the merge-base and one of the two branches agree, the
> merge assumes that the other branch has something new.
>
> If we start creating virtual commits from newer merge-bases, and go
> back to older merge-bases, and then merge with newer commits again,
> chances are that a patch is lost, _because_ the merge-base and the
> head agree on it. Unlikely, yes, but it happened to me.

merge: recursive uses larger conflict markers
Git uses longer conflict markers in the recursive merge base - two more
than the default (thus, 9 character long conflict markers). This allows
users to tell the difference between the recursive merge conflicts and
conflicts between the ours and theirs branches.
This was introduced in git d694a17986a28bbc19e2a6c32404ca24572e400f.
Update our tests to expect this as well.

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.

variable can be freed without being initialized.
Fix the issue by initializing both variables to `NULL`.

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.

merge: Use `git_index__fill` to populate the index
Instead of calling `git_index_add` in a loop, use the new
`git_index_fill` internal API to fill the index with the initial staged
entries.
The new `fill` helper assumes that all the entries will be unique and
valid, so it can append them at the end of the entries vector and only
sort it once at the end. It performs no validation checks.
This prevents the quadratic behavior caused by having to sort the
entries list once after every insertion.

merge: handle conflicts in recursive base building
When building a recursive merge base, allow conflicts to occur.
Use the file (with conflict markers) as the common ancestor.
The user has already seen and dealt with this conflict by virtue
of having a criss-cross merge. If they resolved this conflict
identically in both branches, then there will be no conflict in the
result. This is the best case scenario.
If they did not resolve the conflict identically in the two branches,
then we will generate a new conflict. If the user is simply using
standard conflict output then the results will be fairly sensible.
But if the user is using a mergetool or using diff3 output, then the
common ancestor will be a conflict file (itself with diff3 output,
haha!). This is quite terrible, but it matches git's behavior.

merge: add GIT_MERGE_TREE_FAIL_ON_CONFLICT
Provide a new merge option, GIT_MERGE_TREE_FAIL_ON_CONFLICT, which
will stop on the first conflict and fail the merge operation with
GIT_EMERGECONFLICT.

merge_file: treat large files as binary
xdiff craps the bed on large files. Treat very large files as binary,
so that it doesn't even have to try.
Refactor our merge binary handling to better match git.git, which
looks for a NUL in the first 8000 bytes.

diff: drop `FILELIST_MATCH`
Now that non-pathspec matching diffs are implemented at the iterator
level, drop `FILELIST_MATCH`ing.

diff: use new iterator pathlist handling
When using literal pathspecs in diff with `GIT_DIFF_DISABLE_PATHSPEC_MATCH`
turn on the faster iterator pathlist handling.
Updates iterator pathspecs to include directory prefixes (eg, `foo/`)
for compatibility with `GIT_DIFF_DISABLE_PATHSPEC_MATCH`.

Fix #3094 - improve use of portable size_t/ssize_t format specifiers.
The header src/cc-compat.h defines portable format specifiers PRIuZ, PRIdZ, and PRIxZ. The original report highlighted the need to use these specifiers in examples/network/fetch.c. For this commit, I checked all C source and header files not in deps/ and transitioned to the appropriate format specifier where appropriate.

merge: actually increment the counts, not the pointers
`merge_diff_list_count_candidates()` takes pointers to the source and
target counts, but when it comes time to increase them, we're increasing
the pointer, rather than the value it's pointing to.
Dereference the value to increase.

Rename GIT_EMERGECONFLICT to GIT_ECONFLICT
We do not error on "merge conflicts"; on the contrary, merge conflicts
are a normal part of merging. We only error on "checkout conflicts",
where a change exists in the index or the working directory that would
otherwise be overwritten by performing the checkout.
This *may* happen during merge (after the production of the new index
that we're going to checkout) but it could happen during any checkout.

introduce `git_index_entry_is_conflict`
It's not always obvious the mapping between stage level and
conflict-ness. More importantly, this can lead otherwise sane
people to write constructs like `if (!git_index_entry_stage(entry))`,
which (while technically correct) is unreadable.
Provide a nice method to help avoid such messy thinking.

merge: lock the index at the start of the merge
Always lock the index when we begin the merge, before we write
any of the metdata files. This prevents a race where another
client may run a commit after we have written the MERGE_HEAD but
before we have updated the index, which will produce a merge
commit that is treesame to one parent. The merge will finish and
update the index and the resultant commit would not be a merge at
all.

Make our overflow check look more like gcc/clang's
Make our overflow checking look more like gcc and clang's, so that
we can substitute it out with the compiler instrinsics on platforms
that support it. This means dropping the ability to pass `NULL` as
an out parameter.
As a result, the macros also get updated to reflect this as well.
