[Java 9] Fix GitDateFormatterTest
In JDK 9 and later, the default locale data uses data derived from the
Unicode Consortium's Common Locale Data Repository (CLDR). So there are
changes with respect to some locales.
For example the short date-time format is ‹{1}, {0}› in the CLDR locale,
as opposed to {1} {0} in the JRE locale data.

Walk tag chains for --include-tag options
When cloning repository with --single-branch option, tag chains are not
packed and pack file is broken in some cases.
Typical test-case:
git tag -a test_tag <commit-id>
git tag -a test_prev_tag test_tag
git tag -d test_tag
git clone --single-branch <repository>
fatal: did not receive expected object <test_tag_id>
The reason for that is missing object for original test_tag reference,
which was deleted.
Problem description:
When pack-objects is given --include-tag, it peels each tag reference
down to a commit. If the commit is prepared to be packed, we we have to
include such tag too. The problem is when the tag points to through some
chain of other tag to commit. Then, the inner tags are not added leading
to broken pack.
Fix:
When going to commit, we have to check and add any of the tags on the
way (if they were not selected, which may happen with --single-branch
option).

Repository: Add getIdentifier() method to avoid instanceof operator
This change is needed to implement permission aware ref database in
Gerrit: [1], that is a pre-requisite to re-enable Git v2 protocol in
Gerrit: [2].
Background: Last year Git v2 protocol was enabled in Gerrit. The fact,
that JGit layer was not calling ref advertise filter for Git v2
protocol, introduced security vulnerability.
The lesson learned from this security incident: Gerrit should not rely
on ref advertise filter being called by JGit to implement crictical
security checks. Instead, the idea is to use the same approach as
currently used by Google's internal code on googlesource.com that
didn't suffer from this vulnerability: provide a custom repository to
JGit. The repository provides a RefDatabase that is permission-aware
and will only ever return refs that the user has access to.
However, due to hard coded instanceof operator usages in JGit code
base, some tests in Gerrit are failing with: [1] in place. This change
addresses this problem.

If a new packfile is accessed while it's still racy at least the pack's
