LFS: Adjust some API to make integration into tools (EGit,...) easier
Make the install command accessible without requiring reflection.
Expose the isEnabled(Repository) API to be able to check if calling the
install command is required for a repository.

DirCacheCheckout has a warning about non-localised string "lfs". Other
classes use org.eclipse.jgit.lfs.lib.Constants but that is not visible
to DirCacheCheckout.
Add a new constant in ConfigConstants and use that in DirCacheCheckout.
Replace existing uses of org.eclipse.jgit.lfs.lib.Constants.LFS with
the new constant, except where it is referring to the folder name.

The private method commitNoteMap is in both classes with the same

Make it static in AddNoteCommand and reuse it from RemoveNoteCommand.

LFS: Enable LFS support for the CLI, better error handling
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.

As it is right now some streams leak out of the filter construct. This
change clarifies responsibilities and fixes stream leaks

LFS: support merge/rebase/cherry-pick/diff/compare with LFS files
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.

Correctly exit fetch negotiation for stateless RPC connections
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

DfsReaderIoStats: Clarify that "blocks" are really cache misses
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).

dfs: Try to avoid searching UNREACHABLE_GARBAGE during packing
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.

RepoCommand: persist unreadable submodules in .gitmodules
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.

Don't subclass ThreadLocal to avoid memory leak in NLS
These problem usually occur when you subclass ThreadLocal (usually to
implement initialValue). Those classes reference the webapp's
classloader. The ThreadLocal subclass in turn is referenced by each
Thread instance (that's how ThreadLocals are implemented, they have a
"helper-Map" in each Thread instance, so the leak is actually not a tiny
Random instance but the whole webapp's classloader with a bunch of class
definitions and statically referenced parts of the webapp.
