Sometimes it is useful to obtain metadata associated with an object
without the need to first download it locally. This is specially useful
when using partial clones.
This change implements the object-info capability that allows clients to
query the remote server for object metadata (currently only size). This
is a backport of the same capability that was recently added to the Git
project a2ba162cda (object-info: support for retrieving object info,
2021-04-20).

Trying to register/unregister a shutdown hook when the JVM is already in

With this change bitmap index creation is not blocked on index and
reverse index full initialization in DfsPackFile. Now bitmap index and index could be
read from storage in parallel in separate threads.
Update PackBitmapIndexV1 constructor to get packIndex and reverseIndex
suppliers instead of actual objects. Inner class IdxPositionBitmap was added to initialize pack objects after bitmap
index is fully read from storage. Update DfsPackFile and PackBitmapIndex
accordingly.

Adds functionality to read the git commit.template property. The
template content is read either via a default encoding or, if present,
via encoding specified by i18n.commitEncoding property.

The search for reuse phase for *all* the objects scans *all*
the packfiles, looking for the best candidate to serve back to the
client.
This can lead to an expensive operation when the number of
packfiles and objects is high.
Add parameter "pack.searchForReuseTimeout" to limit the time spent
on this search.

When reading loose objects over NFS it is possible that the OS syscall
would fail with ESTALE errors: This happens when the open file
descriptor no longer refers to a valid file.
Notoriously it is possible to hit this scenario when git data is shared
among multiple clients, for example by multiple gerrit instances in HA.
If one of the two clients performs a GC operation that would cause the
packing and then the pruning of loose objects, the other client might
still hold a reference to those objects, which would cause an exception
to bubble up the stack.
The Linux NFS FAQ[1] (at point A.10), suggests that the proper way to
handle such ESTALE scenarios is to:
"[...] close the file or directory where the error occurred, and reopen
it so the NFS client can resolve the pathname again and retrieve the new
file handle."
In case of a stale file handle exception, we now attempt to read the
loose object again (up to 5 times), until we either succeed or encounter
a FileNotFoundException, in which case the search can continue to
Packfiles and alternates.
The limit of 5 provides an arbitrary upper bounds that is consistent to
the one chosen when handling stale file handles for packed-refs
files (see [2] for context).

The loosen() method has opened pack file and the open pack file handle
may prevent it from being deleted e.g. on Windows. Fix this by closing
the pack file only after loosen() finished.

On a subtree, a PathSuffixFilter must return -1 ("indeterminate"),
not 0 ("include"), otherwise negation goes wrong: an indeterminate
result (-1) is passed on, but a decision (0/1) is inverted.
As a result a negated PathSuffixFilter would skip all folders.

From Git commit 9c1e657a8f:
Currently, the packfile negotiation step within a Git fetch cannot be
done independent of sending the packfile, even though there is at
least one application wherein this is useful - push negotiation.
Therefore, make it possible for this negotiation step to be done
independently.
This feature is for protocol v2 only.
In the protocol, the main hindrance towards independent negotiation is
that the server can unilaterally decide to send the packfile. This is
solved by a "wait-for-done" argument: the server will then wait for
the client to say "done". In practice, the client will never say it;
instead it will cease requests once it is satisfied.
Advertising the server capability option "wait-for-done" is behind the
transport config: uploadpack.advertisewaitfordone, which by default is
false.
