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.

LFS: Add remote download to SmudgeFilter

Fix ssh host name handling for Jsch
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.

Add a minimum negotiation feature for fetch
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.

Bazel: Support building with Java 9
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:
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].

Basic submodule merge handling
This doesn't handle the really hard thing, which is merging spurious
conflicts inside .gitmodules files. That's OK: git.git doesn't
either. Users can resolve the conflict themselves and then commit
the merge.
Previously, jgit would crash when attempting to merge conflicting
submodule changes. Even if there was no conflict, after a merge which
adds submodules, the repository would have been missing empty
directories for newly-added submodules.
This patch fixes the crash, and adds the empty directories where
necessary. It ensures that the index is in a conflicted state when
submodule changes conflict.

Fix index blob for merges with CRLF translations
Commit fc7d407 corrected line endings for working tree files resulting
from merges when CRLF translations are to be done. However, that also
resulted in the file content being put as-is into the index, which is
