RevWalk does not currently provide a --first-parent equivalent and the
feature has been requested.
Add a field to the RevWalk class to specify whether walks should
traverse first parents only. Modify Generator implementations to support
the feature.

If a client clones with "--filter=blob:none", the checkout that "git
clone" automatically does causes the client to fetch all blobs at HEAD.
When fetching from a non-bitmapped repository, this will fail if an
object walk is ever needed, because JGit currently rejects such requests
- see the commit message of d3021788d2 ("Use bitmaps for non-commit
reachability checks", 2017-11-10) for more information.
Rejecting such requests in the absence of bitmaps is probably
overzealous: it is true that the server would prefer to have bitmaps in
this case, but there might be a small proportion of repos (for example,
very small repos or newly created ones) that do not have bitmaps, yet
the server would still like to have partial clones for them.
So, allow such requests, performing the object walk reachability check
if necessary. Limit this to servers with "uploadpack.allowFilter"
configured, so that servers wanting to support partial clone have this
functionality, and servers that do not support partial clone do not have
to pay the object walk reachability check cost.

Archives created by the ArchiveCommand didn't produce deterministic
archive hashes. For RevCommits RevWalk.parseTree returns the root tree
instead of the RevCommit hence retrieving the commit's timestamp didn't
work. Instead use RevWalk.parseAny and extract the tree manually.
Archive entries store timestamps with 1 second resolution hence we need
to wait longer when creating the same archive twice and compare archive
hashes. Otherwise hash comparison in tests wouldn't fail without this
patch.

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.

(cherry picked from commit ee40efcea4)
Error Prone reports the warning on several classes:
[NonOverridingEquals] equals method doesn't override Object.equals;
if this is a type-specific helper for a method that does override
Object.equals, either inline it into the callers or rename it to
avoid ambiguity.
See https://errorprone.info/bugpattern/NonOverridingEquals
Most of these are in the public API, so we can't rename or inline them
without breaking the API. FileSnapshot is not part of the public API,
but clients may be using it anyway, so we also shouldn't change that.
Suppress all the warnings instead. Having the check at severity ERROR
will at least make sure we don't introduce any new occurrences.

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).
