In order to validate .gitmodules files, we first need to find them
in the incoming pack.
Do it in the ObjectChecker stage. Check in the tree objects if they
point to a .gitmodules file and report the tree id and the .gitmodules
blob id.
This can be used later to check if the file is in the root of the
project and if the contents are good.
While we're here, make isMacHFSGit more accurate by detecting variants
of filenames that vary in case.

Support the deepen-since parameter when requested by a client using
protocol v2. This is done by:
- adding a DepthWalk.RevWalk#setDeepenSince method
- updating DepthGenerator to recognize when deepen-since is set
- recording in DepthWalk.Commit whether a commit is a boundary commit
Existing users of DepthWalk such as UploadPack previously recognized
boundary commits by comparing their depths against the threshold, not
tracking whether any parents were truly excluded. This behavior is
preserved - UploadPack considers a commit as boundary if its depth is
equal to the threshold *or* a parent was excluded (whether by depth or
by deepen-since).

In DepthGenerator, commits are always added to the "pending" queue
either at depth 0 (in the constructor) or after a depth check (in
next()), so it is redundant to check for depth after removing them from
the queue. Remove the check.
This redundancy seems to have been present since the introduction of
server-side shallow clone support in commit 9952223e06 ("Implement
server support for shallow clones", 2011-08-21).

When not all branches are cloned, the fetch refspec for the
remote should not be "+refs/heads/*:refs/remotes/origin/*":
that would fetch all branches on the very next fetch, thus
making a clone with only a subset of the branches rather
pointless.
Instead, produce refspecs for the cloned branches only.
Canonical git also does this for its --single-branch case;
it doesn't have an option to clone only a subset of the branches
(only one or all).

FS_POSIX.createNewFile(File) failed to properly implement atomic file
creation on NFS using the algorithm [1]:
- name of the hard link must be unique to prevent that two processes
using different NFS clients try to create the same link. This would
render nlink useless to detect if there was a race.
- the hard link must be retained for the lifetime of the file since we
don't know when the state of the involved NFS clients will be
synchronized. This depends on NFS configuration options.
To fix these issues we need to change the signature of createNewFile
which would break API. Hence deprecate the old method
FS.createNewFile(File) and add a new method createNewFileAtomic(File).
The new method returns a LockToken which needs to be retained by the
caller (LockFile) until all involved NFS clients synchronized their
state. Since we don't know when the NFS caches are synchronized we need
to retain the token until the corresponding file is no longer needed.
The LockToken must be closed after the LockFile using it has been
committed or unlocked. On Posix, if core.supportsAtomicCreateNewFile =
false this will delete the hard link which guarded the atomic creation
of the file. When acquiring the lock fails ensure that the hard link is
removed.

The parsing code for protocol v2 fetch doesn't have any dependency on
the rest of UploadPack.
Move it to its own class. This makes testing easier (no need to
instantiate the full UploadPack), simplifies the code in UploadPack and
increases modularity.
At the moment, the parser needs to know about the reference database to
validate incoming references. This dependency could be easily removed
moving the validation later in the flow, after the parsing, where other
validations are already happening. Postponing that to keep this patch
about moving unmodified code around.

At the moment there are two copies of the client shallow commit list:
one in the request and another in the clientShallowCommits member of
the class.
The verifyShallowCommit function was removing missing object ids
from the member but not the request list, and code afterwards was
using the request's version.
In practice, this didn't cause trouble because these shallow commits
are used as endpoint for a walk, and missing ids are just never reached.

Code can check size instead of null, and that makes the initialization
trivial.

On recent VMs, collection.toArray(new T[0]) is faster than
collection.toArray(new T[collection.size()]). Since it is also more
readable, it should now be the preferred way of collection to array
conversion.

This is actually a fairly common occurrence; deleting the parent
directories can work only if the file deleted was the last one
in the directory.

If packed refs are used, duplicate updates result in an exception
because JGit tries to lock the same lock file twice. With non-atomic
ref updates, this used to work, since the same ref would simply be
locked and updated twice in succession.
Let's be more lenient in this case and remove duplicates before
trying to do the ref updates. Silently skip duplicate updates
for the same ref, if they both would update the ref to the same
object ID. (If they don't, behavior is undefined anyway, and we
still throw an exception.)
Add a test that results in a duplicate ref update for a tag.
