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.

merge: fix potential free of uninitialized memory
The function `merge_diff_mark_similarity_exact` may error our early and,
when it does so, free the `ours_deletes_by_oid` and
`theirs_deletes_by_oid` variables. While the first one can never be
uninitialized due to the first call actually assigning to it, the second
variable can be freed without being initialized.
Fix the issue by initializing both variables to `NULL`.

merge: perform exact rename detection in linear time
The current exact rename detection has order n^2 complexity.
We can do better by using a map to first aggregate deletes and
using that to match deletes to adds.
This results in a substantial performance improvement for merges
with a large quantity of adds and deletes.

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.

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.

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.

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.

Index locking and entry allocation changes
This makes the lock management on the index a little bit broader,
having a number of routines hold the lock across looking up the
item to be modified and actually making the modification. Still
not true thread safety, but more pure index modifications are now
safe which allows the simple cases (such as starting up a diff
while index modifications are underway) safe enough to get the
snapshot without hitting allocation problems.
As part of this, I simplified the allocation of index entries to
use a flex array and just put the path at the end of the index
entry. This makes every entry self-contained and makes it a
little easier to feel sure that pointers to strings aren't
being accidentally copied and freed while other references are
still being held.

Decouple index iterator sort from index
This makes the index iterator honor the GIT_ITERATOR_IGNORE_CASE
and GIT_ITERATOR_DONT_IGNORE_CASE flags without modifying the
index data itself. To take advantage of this, I had to export a
number of the internal index entry comparison functions. I also
wrote some new tests to exercise the capability.

This is just laying some groundwork for internal index changes

revwalk: don't try to find merge bases when there can be none
As a way to speed up the cases where we need to hide some commits, we
find out what the merge bases are so we know to stop marking commits as
uninteresting and avoid walking down a potentially very large amount of
commits which we will never see. There are however two oversights in
current code.
The merge-base finding algorithm fails to recognize that if it is only
given one commit, there can be no merge base. It instead walks down the
whole ancestor chain needlessly. Make it return an empty list
immediately in this situation.
The revwalk does not know whether the user has asked to hide any commits
at all. In situation where the user pushes multiple commits but doesn't
hide any, the above fix wouldn't do the trick. Keep track of whether the
user wants to hide any commits and only run the merge-base finding
algorithm when it's needed.
