Change Ide3445e652 introduced the `--pack-kept-objects` option to GC for
including the objects contained in the locked packfiles during the
repack phase.
Whilst this allowed to explicitly pass a command line argument to the
jgit gc program, it did not allow the option to be read from
configuration.
Allow the pack kept objects option to be configured exactly as C-Git
documents [1], by introducing a new `repack.packKeptObjects`
configuration.
`repack.packKeptObjects` defaults to `true`, when the
`pack.buildBitmaps` is `true` (which is the default case), `false`
otherwise.

Packfiles having an equivalent .keep file are associated with in-flight
pushes that haven't been completed, with potentially a set of git
objects not yet referenced by a ref.
If the Git client is not up-to-date, it may result in pushing a
packfile, generating a <packfile>.keep on the server, which
may also contain existing commits due to the lack of Git protocol
negotiation in the git-receive-pack.
The Git protocol negotiation is the phase where the client and the
server exchange the list of refs they have for trying to find a common
base and minimise the amount of objects to be transferred.
The repack phase in GC was previously skipping all objects that were
contained in all packfiles having a <packfile>.keep file associated
(aka "locked packfiles"), which did not take into consideration the
fact that excluding the existing commits would have resulted in the
generation of an invalid bitmap file.
The code for excluding the objects in the locked packfiles was written
well before the bitmap was introduced, hence could not consider a use
case that did not exist at that time.
However, when the bitmap was introduced, the exclusion of locked
packfiles was not changed, hence creating a potential problem.
The issue went unnoticed for many years because the bitmap generation
was disabled when JGit noticed any locked packfiles; however, the
bitmaps are enabled again since Id722e68d9f , and the the issue is now
visible and is impacting the GC repack phase.
Introduce the '--pack-kept-objects' option in GC for including the
objects contained in the locked packfiles during the repack phase,
which is not an issue because of the following:
- If there are any existing commits duplicated in the packfiles
they will be just considered once anyway because the repack doesn't
generate duplicates in the output packfile.
- If there are any new commits that do not have any ref pointing to
them, they will be automatically excluded from the output repacked
packfile.
The same identical solution is adopted in the C implementation of git
in repack.c.
Because the locked packfile is not pruned, any new commits not pointed
by any refs will remain in the repository and there will not be any
accidental pruning or object loss as it is today before this change.
As a side-effect of this change, it is now potentially possible to still
have duplicate BLOBs after GC when the keep packfile contained existing
objects. However, it is way better to keep the duplication until the
next GC phase rather than omitting existing objects from repacking and,
therefore generating an invalid bitmap and incorrect packfile.

Error Prone is flagging Date-API as obsolete and recommends to migrate
to Instant and LocalDate. Given that more JGit users starting to migrate
to new Time API, offer getInstant method.

Change [1] set refs to null at the beggining of sendPack claiming they
are not needed anymore, but they are still used few lines below to
hoist referenced objects to the front of the pack. With refs nullified,
the hoist doesn't happened. This hasn't caused any problem so far,
probably because it is just an optimization and the objects are in the
pack anyway.
Move the nullification after the hoisting to keep the optimization and
save the memory.

This way we can avoid to access the byte buffers backing array.
Implement a ByteBufferInputStream to wrap a byte buffer which we can use
to expose the filter result as an input stream.
