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].
Replace them with their File counterpart.

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.

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
wrong. The index must contain the file content with reverse CRLF
translations applied.
With core.autocrlf=true, the working tree file should have CR-LF, but
the index blob must still contain only LF.
Fix this oversight and apply the inverse translation when updating the
index, similar to what is done in AddCommand.

Merges are performed using the raw text as stored in the git
repository. When we write the merge result, we must apply the
correct CRLF settings. Otherwise the line endings in the result
will be wrong.

The reason for the change is LFS: when using a lot of LFS files,
checkout can take quite some time on larger repositories. To avoid
"hanging" UI, provide progress reporting.
Also implement (partial) progress reporting for cherry-pick, reset,
revert which are using checkout internally.
The feature is also useful without LFS, so it is independent of it.

Since JGit now requires Java 8, we can switch to TYPE_USE instead
of explicitly specifying the target type.
Some of the existing uses of Nullable need to be reworked slightly
as described in [1] to prevent the compilation error:
scoping construct cannot be annotated with type-use annotation

Revert handling of ssh IdentityFile to pre-4.9 behavior
Jsch caches keys (aka identities) specified in ~/.ssh/config via
IndentityFile only for the current Jsch Session. This results in
multiple password prompts for successive sessions.
Do the handling of IdentityFile exclusively in JGit, as it was before
4.9. JGit uses different Jsch instances per host and caches the
IdentityFile there, allowing it to be re-used in different sessions
for the same host.
* Add comments to explain this.
* Move the JschBugFixingConfig from OpenSshConfig to
JschConfigSessionFactory to have all these Jsch work-arounds
in one place.
* Make that config hide the IdentityFile config from Jsch to avoid
that Jsch overrides the JGit behavior.

RefDirectory#hasLooseRef: Fix stream resource leak reported by error-prone
Error-prone reports:
[StreamResourceLeak] Streams that encapsulate a closeable resource

From the javadoc for Files.list:
"The returned stream encapsulates a DirectoryStream. If timely disposal
of file system resources is required, the try-with-resources construct
should be used to ensure that the stream's close method is invoked
after the stream operations are completed."
This is the only call to Files#newDirectoryStream that is not already in
a try-with-resources.

Use submodule name instead of path as key in config
When a submodule is moved, the "name" field remains the same, while
the "path" field changes. Git uses the "name" field in .git/config
when a submodule is initialized, so this patch makes JGit do so too.

Config: Drop backslash in invalid escape sequences in subsections
These are ignored by C git when parsing:
$ git config -f - --list <<EOF
[foo "x\0y"]
bar = baz
[foo "x\qy"]
bar = baz
[foo "x\by"]
bar = baz
[foo "x\ny"]
bar = baz
[foo "x\ty"]
bar = baz
EOF
foo.x0y.bar=baz
foo.xqy.bar=baz
foo.xby.bar=baz
foo.xny.bar=baz
foo.xty.bar=baz
This behavior is different from value parsing, where an invalid escape
sequence is an error (which JGit already does as well):
$ git config -f - --list <<EOF
[foo]
bar = x\qy
EOF
fatal: bad config line 2 in standard input
