stash: avoid recomputing tree when committing worktree
When creating a new stash, we need to create there separate
commits storing differences stored in the index, untracked
changes as well as differences in the working directory. The
first two will only be done conditionally if the equivalent
options "git stash --keep-index --include-untracked" are being
passed to `git_stash_save`, but even when only creating a stash
of worktree changes we're much slower than git.git. Using our new
stash example:
$ time git stash
Saved working directory and index state WIP on (no branch): 2f7d9d47575e Linux 5.1.7
real 0m0.528s
user 0m0.309s
sys 0m0.381s
$ time lg2 stash
real 0m27.165s
user 0m13.645s
sys 0m6.403s
As can be seen, libgit2 is more than 50x slower than git.git!
When creating the stash commit that includes all worktree
changes, we create a completely new index to prepare for the new
commit and populate it with the entries contained in the index'
tree. Here comes the catch: by populating the index with a tree's
contents, we do not have any stat caches in the index. This means
that we have to re-validate every single file from the worktree
and see whether it has changed.
The issue can be fixed by populating the new index with the
repo's existing index instead of with the tree. This retains all
stat cache information, and thus we really only need to check
files that have changed stat information. This is semantically
equivalent to what we previously did: previously, we used the
tree of the commit computed from the index. Now we're just using
the index directly.
And, in fact, the cache is doing wonders:
time lg2 stash
real 0m1.836s
user 0m1.166s
sys 0m0.663s
We're now performing 15x faster than before and are only 3x
slower than git.git now.

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.

stash: use _an_ index not _the_ index
Don't manipulate the repository's index during stash; instead,
manipulate a temporary index and check it out.
This allows us to use the checkout mechanism to update the workdir and
the repository's index, and allows checkout to use its common mechanisms
to write data and handle errors.

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.

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.

stash: save the workdir file when deleted in index
When stashing the workdir tree, examine the index as well. Using
a mechanism similar to `git_diff_tree_to_workdir_with_index`
allows us to determine that a file was added in the index and
subsequently modified in the working directory. Without examining
the index, we would erroneously believe that this file was
untracked and fail to include it in the working directory tree.
Use a slightly modified `git_diff_tree_to_workdir_with_index` in
order to avoid some of the behavior custom to `git diff`. In
particular, be sure to include the working directory side of a
file when it was deleted in the index.

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.

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.

stash: use a transaction to modify the reflog
The stash is implemented as the refs/stash reference and its reflog. In
order to modify the reflog, we need avoid races by making sure we're the
only ones allowed to modify the reflog.
We achieve this via the transactions API. Locking the reference gives us
exclusive write access, letting us modify and write it without races.

Make stash and checkout ignore contained repos
To emulate git, stash should not remove untracked git repositories
inside the parent repo, and checkout's REMOVE_UNTRACKED should
also skip over these items.
`git stash` actually prints a warning message for these items.
That should be possible with a checkout notify callback if you
wanted to, although it would require a bit of extra logic as things
are at the moment.

Remove converting user error to GIT_EUSER
This changes the behavior of callbacks so that the callback error
code is not converted into GIT_EUSER and instead we propagate the
return value through to the caller. Instead of using the
giterr_capture and giterr_restore functions, we now rely on all
functions to pass back the return value from a callback.
To avoid having a return value with no error message, the user
can call the public giterr_set_str or some such function to set
an error message. There is a new helper 'giterr_set_callback'
that functions can invoke after making a callback which ensures
that some error message was set in case the callback did not set
one.
In places where the sign of the callback return value is
meaningful (e.g. positive to skip, negative to abort), only the
negative values are returned back to the caller, obviously, since
the other values allow for continuing the loop.
The hardest parts of this were in the checkout code where positive
return values were overloaded as meaningful values for checkout.
I fixed this by adding an output parameter to many of the internal
checkout functions and removing the overload. This added some
code, but it is probably a better implementation.
There is some funkiness in the network code where user provided
callbacks could be returning a positive or a negative value and
we want to rely on that to cancel the loop. There are still a
couple places where an user error might get turned into GIT_EUSER
there, I think, though none exercised by the tests.

Further EUSER and error propagation fixes
This continues auditing all the places where GIT_EUSER is being
returned and making sure to clear any existing error using the
new giterr_user_cancel helper. As a result, places that relied
on intercepting GIT_EUSER but having the old error preserved also
needed to be cleaned up to correctly stash and then retrieve the
actual error.
Additionally, as I encountered places where error codes were not
being propagated correctly, I tried to fix them up. A number of
those fixes are included in the this commit as well.

reflog: integrate into the ref writing
Whenever a reference is created or updated, we need to write to the
reflog regardless of whether the user gave us a message, so we shouldn't
leave that to the ref frontend, but integrate it into the backend.
This also eliminates the race between ref update and writing to the
reflog, as we protect the reflog with the ref lock.
As an additional benefit, this reflog append on the backend happens by
appending to the file instead of parsing and rewriting it.

No such thing as an orphan branch
Unfortunately git-core uses the term "unborn branch" and "orphan
branch" interchangeably. However, "orphan" is only really there for
the checkout command, which has the `--orphan` option so it doesn't
actually create the branch.
Branches never have parents, so the distinction of a branch with no
parents is odd to begin with. Crucially, the error messages deal with
unborn branches, so let's use that.

Reorganize diff and add basic diff driver
This is a significant reorganization of the diff code to break it
into a set of more clearly distinct files and to document the new
organization. Hopefully this will make the diff code easier to
understand and to extend.
This adds a new `git_diff_driver` object that looks of diff driver
information from the attributes and the config so that things like
function content in diff headers can be provided. The full driver
spec is not implemented in the commit - this is focused on the
reorganization of the code and putting the driver hooks in place.
This also removes a few #includes from src/repository.h that were
overbroad, but as a result required extra #includes in a variety
of places since including src/repository.h no longer results in
pulling in the whole world.

Improve error propagation in stash
Stash was sometimes obscuring the actual error code, replacing it
with a -1 when there was more descriptive value. This updates
stash to preserve the original error code more reliably along
with a variety of other error handling tweaks.
I believe this is an improvement, but arguably, preserving the
underlying error code may result in values that are harder to
interpret by the caller who does not understand the internals.
Discussion is welcome!

Rework checkout internals (again)
I've tried to map out the detailed behaviors of checkout and make
sure that we're handling the various cases correctly, along with
providing options to allow us to emulate "git checkout" and "git
checkout-index" with the various flags. I've thrown away flags
in the checkout API that seemed like clutter and added some new
ones. Also, I've converted the conflict callback to a general
notification callback so we can emulate "git checkout" output and
display "dirty" files.
As of this commit, the new behavior is not working 100% but some
of that is probably baked into tests that are not testing the
right thing. This is a decent snapshot point, I think, along the
way to getting the update done.

Fix diff constructor name order confusion
The diff constructor functions had some confusing names, where the

reverses the order in the function name to make it less confusing.
Specifically...

* git_diff_workdir_to_index becomes git_diff_index_to_workdir
* git_diff_workdir_to_tree becomes git_diff_tree_to_workdir

Add explicit git_index ptr to diff and checkout
A number of diff APIs and the `git_checkout_index` API take a
`git_repository` object an operate on the index. This updates
them to take a `git_index` pointer explicitly and only fall back
on the `git_repository` index if the index input is NULL. This
makes it easier to operate on a temporary index.

Fix diff API to better parameter order
The diff API is not in the parameter order one would expect from
other libgit2 APIs. This fixes that.

Rework checkout with new strategy options
This is a major reworking of checkout strategy options. The
checkout code is now sensitive to the contents of the HEAD tree
and the new options allow you to update the working tree so that
it will match the index content only when it previously matched
the contents of the HEAD. This allows you to, for example, to
distinguish between removing files that are in the HEAD but not
in the index, vs just removing all untracked files.
Because of various corner cases that arise, etc., this required
some additional capabilities in rmdir and other utility functions.
This includes the beginnings of an implementation of code to read
a partial tree into the index based on a pathspec, but that is
not enabled because of the possibility of creating conflicting
index entries.
