settings: optional unsaved index safety
Add the `GIT_OPT_ENABLE_UNSAVED_INDEX_SAFETY` option, which will cause
commands that reload the on-disk index to fail if the current
`git_index` has changed that have not been saved. This will prevent
users from - for example - adding a file to the index then calling a
function like `git_checkout` and having that file be silently removed
from the index since it was re-read from disk.
Now calls that would re-read the index will fail if the index is
"dirty", meaning changes have been made to it but have not been written.
Users can either `git_index_read` to discard those changes explicitly,
or `git_index_write` to write them.

index: commit the changes to the index properly
Now that the index has a "dirty" state, where it has changes that have
not yet been committed or rolled back, our tests need to be adapted to
actually commit or rollback the changes instead of assuming that the
index can be operated on in its indeterminate state.

index: test dirty index bit
Test that any changes to the index will mark the index as dirty. Also
ensure that when we initialize a new index, read the index contents
from disk, or write the index contents to disk that we reset the dirty
flag to zero. Further ensure that an unforced read with dirty contents
(when the on-disk index has not changed) does _not_ reset the dirty
flag as we have not updated the contents of our index and our unsaved
contents remain intact.

index::reuc tests: test that checkout succeeds
The index::reuc tests must test that the checkout itself succeeds,
otherwise subsequent tests are not valid.
In fact, the checkouts were failing because when checking out `SAFE`,
they cannot update the files that are in conflict. Change the checkout
level to `FORCE` to ensure that they get updated correctly.

index::names tests: add conflicts with high stages
We add entries into the main index to correspond with the NAME entries
that we're going to test. NAME entries store the results of conflicts
occuring with rename detection during merge, and they must correspond to
conflicts in the index.
This test was mistakenly adding regular entries. The checkout
validation failed, since it requires NAME entries to correspond to
high-stage (conflict) entries. Correct the test to actually create
conflicts.

tests: index::filemodes: fix use of uninitialized memory
The new index entry structure was not being initialized to all-zeroes.
As that structure is used to add a new entry to the current index, and
the hashing algorithm of the index making use of the uninitialized flags
to calculate the state, we might miscompute the hash of the entry and
add it at the wrong position. Later lookups would then fail.
Initialize the structure with `memset` to fix the test breaking on some
platforms.

submodule from a string; there's no possible path to success.

tests: index::tests: create sandboxed repo for locking
The test `index::tests::can_lock_index` operates on the "testrepo.git"
repository located inside of our source tree. While this is okay for
tests which do read-only operations on these resouces, this specific
test tries to lock the index by creating a lock. This will obviously
fail on out-of-tree builds with read-only source trees.
Fix the issue by creating a sandbox first.

tests: index::version: improve write test for index v4
The current write test does not trigger some edge-cases in the index
version 4 path compression code. Rewrite the test to start off the an
empty standard repository, creating index entries with interesting paths
itself. This allows for more fine-grained control over checked paths.
Furthermore, we now also verify that entry paths are actually
reconstructed correctly.

tests: index::version: verify we write compressed index entries
While we do have a test which checks whether a written index of version
4 has the correct version set, we do not check whether this actually
enables path compression for index entries. This commit adds a new test
by adding a number of index entries with equal path prefixes to the
index and subsequently flushing that to disk. With suffix compression
enabled by index version 4, only the last few bytes of these paths will
actually have to be written to the index, saving a lot of disk space.
For the test, differences are about an order of magnitude, allowing us
to easily verify without taking a deeper look at actual on-disk
contents.

which has an index of version 4. This repository is then read from a new
test.

racy: make git_index_read_index handle raciness
Ensure that `git_index_read_index` clears the uptodate bit on
files that it modifies.
Further, do not propagate the cache from an on-disk index into
another on-disk index. Although this should not be done, as
`git_index_read_index` is used to bring an in-memory index into
another index (that may or may not be on-disk), ensure that we do
not accidentally bring in these bits when misused.

index: test for smudged entries on write only
Test that entries are only smudged when we write the index: the
entry smudging is to prevent us from updating an index in a way
that it would be impossible to tell that an item was racy.
Consider when we load an index: any entries that have the same
(or newer) timestamp than the index itself are considered racy,
and are subject to further scrutiny.
If we *save* that index with the same entries that we loaded,
then the index would now have a newer timestamp than the entries,
and they would no longer be given that additional scrutiny, failing
our racy detection! So test that we smudge those entries only on
writing the new index, but that we can detect them (in diff) without
having to write.

index: don't detect raciness in uptodate entries
Keep track of entries that we believe are up-to-date, because we
added the index entries since the index was loaded. This prevents
us from unnecessarily examining files that we wrote during the
cleanup of racy entries (when we smudge racily clean files that have
a timestamp newer than or equal to the index's timestamp when we
read it). Without keeping track of this, we would examine every
file that we just checked out for raciness, since all their timestamps
would be newer than the index's timestamp.

index: also try conflict mode when inserting
When we do not trust the on-disk mode, we use the mode of an existing

If there is no stage 0 index entry, also look at conflicts to attempt
to answer this question: prefer the data from the 'ours' side, then
the 'theirs' side before falling back to the common ancestor.

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.

git_index_add: allow case changing renames
On case insensitive platforms, allow `git_index_add` to provide a new
path for an existing index entry. Previously, we would maintain the
case in an index entry without the ability to change it (except by
removing an entry and re-adding it.)
Higher-level functions (like `git_index_add_bypath` and
`git_index_add_frombuffers`) continue to keep the old path for easier
usage.

index: canonicalize directory case when adding
On case insensitive systems, when given a user-provided path in the
higher-level index addition functions (eg `git_index_add_bypath` /
`git_index_add_frombuffer`), examine the index to try to match the
given path to an existing directory.
Various mechanisms can cause the on-disk representation of a folder
to not match the representation in HEAD or the index - for example,
a case changing rename of some file `a/file.txt` to `A/file.txt`
will update the paths in the index, but not rename the folder on
disk.
If a user subsequently adds `a/other.txt`, then this should be stored
in the index as `A/other.txt`.

Fix index-adding functions to know when to trust filemodes.
The idea...sometimes, a filemode is user-specified via an
explicit git_index_entry. In this case, believe the user, always.
Sometimes, it is instead built up by statting the file system. In
those cases, go with the existing logic we have to determine
whether the file system supports all filemodes and symlinks, and
make the best guess.
On file systems which have full filemode and symlink support, this
commit should make no difference. On others (most notably Windows),
this will fix problems things like:
* git_index_add and git_index_add_frombuffer() should be believed.
* As a consequence, git_checkout_tree should make the filemodes in
the index match the ones in the tree.
* And diffs with GIT_DIFF_UPDATE_INDEX don't write the wrong filemodes.
* And merges, and probably other downstream stuff now fixed, too.
This makes my previous changes to checkout.c unnecessary,
so they are now reverted.
Also, added a test for index_entry permissions from git_index_add
and git_index_add_frombuffer, both of which failed before these changes.

reset: remove reflog message override
This function is meant to simulate what git does in the reset command,
so we should include the reflog message in that.

Remove the signature from ref-modifying functions
The signature for the reflog is not something which changes
dynamically. Almost all uses will be NULL, since we want for the
repository's default identity to be used, making it noise.
In order to allow for changing the identity, we instead provide
git_repository_set_ident() and git_repository_ident() which allow a user
to override the choice of signature.

Add API to add a memory buffer to an index
git_index_add_frombuffer enables now to store a memory buffer in the odb
and to store an entry in the index directly if the index is attached to a
repository.

git_indexwriter: lock then write the index
Introduce `git_indexwriter`, to allow us to lock the index while
performing additional operations, then complete the write (or abort,
unlocking the index).

Create miscapitialised dirs for case-sensitive filesystems
We need these directories to exist so cl_git_mkfile() can create the
files we ask it to.

treebuilder: take a repository for path validation
Path validation may be influenced by `core.protectHFS` and
`core.protectNTFS` configuration settings, thus treebuilders
can take a repository to influence their configuration.

tree-cache: correct the entry_count calculation
The entry_count field is the amount of index entries covered by a
particular cache entry, that is how many files are there (recursively)
under a particular directory.
The current code that attemps to do this is severely defincient and is
trying to count the amount of children, which always comes up to zero.
We don't even need to recount, since we have the information during the
cache creation. We can take that number and keep it, as we only ever
invalidate or replace.

index: make sure to write cached subtrees if parent is invalidated
If e.g. the root tree is invalidated, we still want to write out
its children, since those may still have valid cache entries.

index: write out the tree cache extension
Keeping the cache around after read-tree is only one part of the
optimisation opportunities. In order to share the cache between program
instances, we need to write the TREE extension to the index.
Do so, taking the opportunity to rename 'entries' to 'entry_count' to
match the name given in the format description. The included test is
rather trivial, but works as a sanity check.

index: add tests for the tree cache
These test that we invalidate at the right levels and that we remove the
tree cache when clearing the index.

Make core.safecrlf work on LF-ending platforms
If you enabled core.safecrlf on an LF-ending platform, we would
error even for files with all LFs. We should only be warning on
irreversible mappings, I think.
