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.

IndexEventConsumer metrics are reported per index PackExt and reverse
indexes did not have one, so they were not included.
Now that there is a REVERSE_INDEX PackExt, enable reporting
IndexEventConsumer metrics for reverse indexes.

Keys used for identifying reverse indexes in the DfsBlockCache use a
custom subclass ForReverseIndex because there was no PackExt for them.
This conflates BlockCacheMetrics for reverse indexes with those for
packs, since the key falls back onto 0 when there is no extension.
Replace the custom ForReverseIndex with a DfsStreamKey usage to bring
keys for the new REVERSE_INDEX extension in line with INDEX and BITMAP
and separate reverse index and pack BlockCacheMetrics.

There is no reverse index PackExt because the reverse index is not currently
written to a file. This prevents fine-grained performance reporting for reverse
indexes, which will be useful when introducing a reverse index file and
observing performance changes.
Add a reverse index extension that matches the one in cgit
(9bf691b78c/Documentation/gitformat-pack.txt (L302))
in preparation for adding a reverse index file while observing
performance before and after.
