Since [1] the gerrit project includes jgit as a submodule, and has this
warning enabled, resulting in 100s of warnings in the console.
Also enable the warning here, and fix them.
At the same time, add missing braces around adjacent and nearby one-line
blocks.

On changing a ref, the old SHA1 is not updated in the object => ref
mapping. This means search by object ID may still turn up a ref from
deeper within the stack. To fix this, check all refs produced by the
merged iterator against the merged reftables.

The flag enabling sideband-all is used in two places: in UploadPack
for advertisement and in the protocol parser to read it from the
request.
This leds to problems in distributed deployments where the two requests of
a fetch can go to different servers with different configurations.
Use the existing allowsidebandall to accept the sideband-all request
(and respond to it) and introduce a new "advertisesidebandall" to toggle
the advertising of the feature.

The object identifying packfiles to send them via packfile-uri contains
only the uri and the hash. This is the information that goes through the
wire. It would be useful to know also the size of those packfile, for
example to track how many bytes have been offloaded to HTTP.
Add size field the CachedPackUriProvider.PackInfo object.

MergedReftable is not used as an AutoCloseable, because closing tables
is currently handled by DfsReftableStack#close.
Encode that a MergedReftable is a list of ReftableReaders. The previous
code suggested that we could form nested trees of MergedReftables,
which is not how we use reftables.

This makes the intended use of the classes more clear. It also
simplifies generic functions that write reftables: they only need a
ReftableWriter as argument, as the stream is carried within the
ReftableWriter.

UploadPackTest is already too long and it is covering too many aspects
of UploadPack. This makes difficult to see what is tests and if all
cases are covered.
Move the reachability-related tests to its own file. This moves also an
auxiliary function, reducing the length of UploadPack. Complete also the
coverage, adding combinations of bitmap availability/commits or
blobs/reachable or not.

Older JGit stored only milliseconds timestamps in the index. Newer
JGit may get finer timestamps from the file system. This leads to
slow index diffs when a new JGit runs against an index produced
by older JGit because many timestamps will differ and JGit will
then do many content checks. See [1].
Handle this migration case by only comparing milliseconds if the
index entry has only millisecond precision.
The inverse may also occur; also compare only milliseconds if the
file timestamp has only millisecond precision.
Do the same also for microsecond resolution. On Windows, NTFS may
provide 100ns resolution and may be used by external programs writing
the index, but Java's WindowsFileAttributes may provide only
microseconds.
File timestamp precision in Java depends not only on the Java APIs
used by different JGit versions but may also change when running the
same Java code on different VMs. And of course the resolution may
vary among operating and file systems. Moreover, timestamp precision
in the index depends on the program that wrote the index. Canonical
git may use a different resolution, maybe even different between git
versions.

Since commit c3b0dec509fe136c5417422f31898b5a4e2d5e02, Git has
disallowed writing a non-commit to refs/heads/* refs. JGit still
allows that, which can put users in a bad situation. For example,
git push origin v1.0:master
pushes the tag object v1.0 to refs/heads/master, instead of the
intended commit object v1.0^{commit}.
Prevent that by validating that the target of the ref points to a
commit object when pushing to refs/heads/*.
Git performs the same check at a lower level (in the RefDatabase). We
could do the same here, but for now let's start conservatively by
handling it in pushes first.

(cherry picked from commit e54fde8616)
PackedBatchRefUpdate was creating a new packed-refs list that was
potentially unsorted. This would be papered over when the list was
read back from disk in parsePackedRef, which detects unsorted ref
lists on reading, and sorts them. However, the BatchRefUpdate also
installed the new (unsorted) list in-memory in
RefDirectory#packedRefs.
With the timestamp granularity code committed to stable-5.1, we can
more often accurately decide that the packed-refs file is clean, and
will return the erroneous unsorted data more often. Unluckily timed
delays also cause the file to be clean, hence this problem was
exacerbated under load.
The symptom is that refs added by a BatchRefUpdate would stop being
visible directly after they were added. In particular, the Gerrit
integration tests uses BatchRefUpdate in its setup for creating the
Admin group, and then tries to read it out directly afterward.
The tests recreates one failure case. A better approach would be to
revise RefList.Builder, so it detects out-of-order lists and
automatically sorts them.

(cherry picked from commit a024759cf5)
This test case assumed file system timestamp resolution of 1 second. On
filesystems with a finer resolution this test fails since the index
entry is only smudged if the file index entry's lastModified and the
lastModified of the git index itself are within the same filesystem
timer tick. Fix this by ensuring that these timestamps are identical
which should work for any filesystem timer resolution.
