This is based on the ObjectIdSerialization class written by Shawn Pearce
for the Gerrit Code Review project in 2009 [1]. As mentioned in the
commit message there, it should be part of core JGit.
This implementation is slightly different to Shawn's version. Rather
than having separate methods for null/non-null ids, single methods are
implemented with @Nullable annotations.

Processing of negated rules, like !bin/ was not working correctly: they
were interpreted too broad, resulting in unexpected untracked files
which should actually be ignored

The previous wording was ambiguous as to whether these were blocks
requested from the cache (hits + misses) or read from underlying storage
(misses only).
They are in fact recording only misses:
Accumulator#{readBlock,readBlockBytes,readBlockMicros} are only
incremented from BlockBasedFile#readOneBlock, which is only called from
the cache miss path in DfsBlockCache#getOrLoad (line 391).

RepoCommand: generate relative submodule URLs from absolute URLs.
RepoCommand: don't record new commit if tree did not change
RepoCommand: persist unreadable submodules in .gitmodules
If an object can be found in a non-garbage pack, favor that pack over
paging in the garbage pack's idx and pack content.
Only fall back to garbage packs if an object cannot be found and there
are garbage packs present in the repository. This fallback is
required to correct race conditions during GC.

In cases where a manifest file mixes different remotes, a Gerrit
server process may not have access to all remotes, and won't be able
to produce a full submodule tree.
Preserving this information in .gitmodules will let downstream clients
reconstruct the full tree.

Transfer data in chunks of 8k Transferring data byte per byte is slow,
running checkout with CleanFilter on a 2.9MB file takes 20 seconds.
Using a buffer of 8k shrinks this time to 70ms.
Also register the filter commands in a way that the native GIT LFS can
be used alongside with JGit.
Implements auto-discovery of LFS server URL when cloning from a Gerrit
LFS server.

When the command is run on a non-bare repository, an instance of
Git is created to execute the commit, and is left open when the
command has finished.
Refactor to not use a class scope Git instance, and make sure it
gets closed before returning.

If we give Jsch access to the ssh config file, we must _not_ resolve
the host name from the alias. Instead we must give the alias (i.e.,
the host name as is in the URI) to Jsch, so that it finds the same
ssh config entry.
Otherwise if the hostname in the URI, which is taken as an alias in
ssh config ("Host" line), is unequal to the "Hostname" line, and
there happens to be another ssh config entry with that translated
host name as alias, Jsch will pick up that second entry, and we end
up with a strange mixture of both.
Add tests for this case.

Jsch unconditionally overwrites the port from the ssh config
file (if a port is specified there), even if the URI explicitly does
give a different port.
Fix this, and add tests.

The InitCommand returns a Git that is instantiated with the newly
created Repository, but the Repository is not closed with the Git
resulting in resource leaks.
Create the Git with `closeRepo` set to true, such that the Repository
is also closed when the Git is closed.
Adjust the tests to use try-with-resource on the Git instance.

Android an Chrome have several repos with >300k refs. We sometimes see
negotiations of >100k rounds. This change provides a "minimal negotiation"
feature on the client side that limits how many "have" lines the client
sends. The client extracts the current SHA-1 values for the refs in its
wants set, and terminates negotiation early when all of those values have
been sent as haves. If a new branch is being fetched then that set will
be empty and the client will terminate after current default minimum
of two rounds.
This feature is gated behind a "fetch.useminimalnegotiation" configuration
flag, which defaults to false.

Add fetch statistics for the counts of advertised refs, wants and haves.
Also add the duration in milliseconds for the negotiation phase. For
non-bidirectional transports like HTTP, this is the time for the final
round that sends the pack back to the user.

When CleanCommand is collecting the files and folders to be deleted
it may happen that the list of directories contains obsolete entries.
E.g. a folder and its parent folder may be in the list. Only the
parent folder would be sufficient.
This was a reason for hitting FileNotFoundExceptions when finally
trying to delete the files and folders. Improve CleanCommand
to ignore files to be deleted which are already gone.

After packaging references, the folders containing these references are
not deleted. In a busy repository, this causes operations to slow down
as traversing the references tree becomes longer.
Delete empty reference folders after the loose references have been
packed.
To avoid deleting a folder that was just created by another concurrent
operation, only delete folders that were not modified in the last 30
seconds.

Bazel@HEAD supports Java 9.
The current code has one single issue with Java 9 compliance: the usage
of javax.xml.bind.DatatypeConverter class for printHexBinary() method.
This class is not available on Java 9. One alternative is to use guava
library. Something similar was done here: [1]. But unlike the case with
checkstyle library, JGit currently doesn't use guava. Instead, we add
java.xml.bind module with --add-modules compiler option.
To build (or test) with Java 9, build custom bazel version and issue:
$ bazel --host_javabase=/usr/lib64/jvm/java-9-openjdk build \
--javacopt='--release 9' \
--java_toolchain=@bazel_tools//tools/jdk:toolchain_jdk9 :all
The Java 9 support is backwards compatible.

The Files.exists method has noticeably poor performance in JDK 8 and can
slow an application significantly when used to check files that do not
actually exist. The same goes for Files.notExists, Files.isDirectory and
Files.isRegularFile [1].
