Remove use of deprecated getAllRefs() in ReceivePack
Repository.getAllRefs() is deprecated and should not
be used anymore. Leverage the ref-db and the retrieval
of refs by prefix and adapt the result to the expected
refname/ref map.

searchForReuse might impact performance in large repositories
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.

Retry loose object read upon "Stale file handle" exception
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).

Fix garbage collection failing to delete pack file
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.

Fix PathSuffixFilter: can decide only on full paths
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.

Apache MINA sshd doesn't log all values, but it'd be very helpful to

Teach independent negotiation (no pack file) using an option "wait-for-done"
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.
