Enable LFS support for the CLI by registering the according filters.
Errors during filter creation must be propagated up the call stack, as a
failure to create a filter should be treated as fatal if the filter is
required.

Respect merge=lfs and diff=lfs attributes where required to replace (in
memory) the content of LFS pointers with the actual blob content from
the LFS storage (and vice versa when staging/merging).
Does not implement general support for merge/diff attributes for any
other use case apart from LFS.

SSH Authentication is quite expensive (~120ms on localhost against
Gerrit with LFS plugin). The SSH authentication typically also sends a
validity time of the returned token, which allows to re-use it for a
certain time, avoiding the expensive authentication on every download
request. This improves checkout times by large factors depending on the
LFS object amount/sizes.
Also make sure that all instances of Gson used by LFS are configured in
the same way.

Commit 9530c10192 (2018-02-11)
"Add a minimum negotiation feature for fetch" made fetch
negotiation cheaper for repos with huge numbers of
references (we are seeing a 15x reduction in maximum fetch
times for chromium/chromium/src on trans-Pacific links).
But it inadvertently broke the handling of stateless RPC
connections, so fix that here.

If JGit built in LFS support is enabled for the current repository (or
user/system), any existing pre-push hook will cause an exception for the
time beeing, as only a single pre-push hook is supported.
Thus either native pre-push hooks OR JGit built-in LFS support may be
enabled currently, but not both.

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).

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.

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.
