Git introduced a new file storing the topology and some metadata of
the commits in the repo (commitGraph). With this data, git can browse
commit history without parsing the pack, speeding up e.g.
reachability checks.
This change teaches JGit to read commit-graph-format file, following
the upstream format([1]).
JGit can read a commit-graph file from a buffered stream, which means
that we can provide this feature for both FileRepository and
DfsRepository.

Deleting orphan files depends on .pack and .keep being reverse-sorted
to before the corresponding index files that could be orphans. The new
reverse index file extension (.rev) will break that frail dependency.
Rewrite Gc#deleteOrphans to avoid that dependence by tracking which pack
names have a .pack or .keep file and then deleting any index files that
without a corresponding one. This approach takes linear time instead of
the O(n logn) time needed for sorting.

These paths are given to the underlying URI-based transports (s3, sftp,
http), all of which expect forward-slash as the path separator
character.

CommitGraphWriter uses the GraphCommits in for-each loops and doesn't
need the access by position anymore. This was a left-over from
https://git.eclipse.org/r/c/jgit/jgit/+/182832
Remove the unused method.

Errorprone run in the bazel build raised this exception:
org.eclipse.jgit/src/org/eclipse/jgit/internal/storage/commitgraph/CommitGraphWriter.java:105:
error: [UnusedException] This catch block catches an exception and
re-throws another, but swallows the caught exception rather than setting
it as a cause. This can make debugging harder.

Did you mean 'throw new
IOException(JGitText.get().commitGraphWritingCancelled, e);'?

Since Oomph's p2 repo for jetty 10.0.13 doesn't have source bundles, we
remove them. Eclipse platform doesn't create p2 repos for jetty anymore
and we aren't yet ready to use maven dependencies like the platform
does.

There is no commit graph PackExt because the non-DFS stack is not writing using PackExt mechanism. The extension is needed in DFS to determine the stream to write the commit-graph.
Add a commit graph extension that matches the one in cgit
(https://git-scm.com/docs/commit-graph#_file_layout)
in preparation for adding DFS support for reading and writing commit graphs.

The expression RefUpdate ru = newUpdate(cmd) is eagerly evaluated before the switch statement.
But it is not used in some switch cases and thus is calculated uselessly.
Move expression evaluation to the switch case where it is actually used.
After such a move, several cases became identical and thus were squashed.

After checking the variable, the same variable was checked again inside
the "if" block, and after the first check, this variable does not
change. Remove the second unnecessary check.

The NameConflictTreeWalk class is used in merge for iterating over
entries in commits. The class uses a separate iterator for each
commit's tree. In rare cases it can incorrectly report the same entry
twice. As a result, duplicated entries are added to the merge result
and later jgit throws an exception when it tries to process merge
result.
The problem appears only when there is a directory-file conflict for
the last item in trees. Example from the bug:
Commit 1:
* subtree - file
* subtree-0 - file
Commit 2:
* subtree - directory
* subtree-0 - file
Here the names are ordered like this:
"subtree" file <"subtree-0" file < "subtree" directory.
The NameConflictTreeWalk handles similar cases correctly if there are
other files after subtree... in commits - this is processed in the
AbstractTreeIterator.min function. Existing code has a special
optimization for the case, when all trees are pointed to the same
entry name - it skips additional checks. However, this optimization
incorrectly skips checks if one of trees reached the end.
The fix processes a situation when some trees reached the end, while
others are still point to an entry.

Due to this platform style migration: [1] the RBE toolchain needs to be
updated to use the latest rbe_config_gen from bazel-toolchains (at least
version 5.1.2 so that it contains: [2]).
This change makes RBE build forwards compatible so that Bazel could be
updated to the upcoming major 6.0 release.
