Purpose of the next branch is preparation of breaking changes before
we know when we will release it. Bump the version to the next major
release 6.0.0-SNAPSHOT in order to prevent build results compete with
build results from the version currently used on the master branch
(5.7.0-SNAPSHOT).

RevWalk: stop mixing lines of history in topo sort
The topological sort algorithm in TopoSortGenerator for RevWalk may mix
multiple lines of history, producing results that differ from C git's
git log whose man page states: "Show no parents before all of its
children are shown, and avoid showing commits on multiple lines of
history intermixed." Lines of history are mixed because
TopoSortGenerator merely delays a commit until all of its children have
been produced; it does not immediately produce a commit after its last
child has been produced.
Therefore, when the last child of a commit has been produced, unpop the
commit so that it will be returned upon the subsequent call to next() in
TopoSortGenerator. To avoid producing duplicates, mark commits that
have not yet been produced as TOPO_QUEUED so that when a commit is
popped, it is produced if and only if TOPO_QUEUED is set.
To support nesting with other generators that may produce the same
commit multiple times like DepthGenerator (for example, StartGenerator
does this), do not increment parent inDegree for the same child commit
more than once.
Modify tests that assert that TopoSortGenerator mixes lines of commit
history.

The ReftableCompactor supported a byteLimit, but this is currently
unused. The FileReftableStack has a more sophisticated strategy that
amortizes compaction costs.
Rename min/maxUpdateIndex to reflogExpire{Min,Max}UpdateIndex to
reflect their purpose more accurately.
Since reflogs are generally pruned chronologically (oldest entries are
expired first), one can only prune entries on full compaction, so they
should not be set by default.
Rephrase the function Reader#minUpdateIndex and maxUpdateIndex. These
vars are documented to affect log entries, but semantically, they are
about ref entries. Since ref entries have their timestamps
delta-compressed, it is important for the min/maxUpdateIndex values to
be coherent between different tables.
The logical timestamps for log entries do not have to be coherent in
different tables, as the timestamps of a log entry is part of the key.
For example, a table written at update index 20 may contain a tombstone
log entry at timestamp 1.
Therefore, we set ReftableWriter's min/maxUpdateIndex from the merged
tables we are compacting, rather than from the compaction settings
(which should only control reflog expiry.)
The previous behavior could drop log entries erroneously, especially
in the presence of tombstone log entries. Unfortunately, testing this
properly requires both an API for adding log tombstones, and a more
refined API for controlling automatic compaction. Hence, no test.

Previously, the list of tables was in .git/refs. This makes
repo detection fail in older clients, which is undesirable.
This is proposal was discussed and approved on the git@vger list at
https://lore.kernel.org/git/CAFQ2z_PvKiz==GyS6J1H1uG0FRPL86JvDj+LjX1We4-yCSVQ+g@mail.gmail.com/
For backward compatibility, JGit could detect a file under .git/refs and
use it as a reftable list.

The merged table contains handles to open files. A full compaction
causes those files to be closed, and so further lookups would fail
with EBADF.

Commit 6216b0de changed the behavior of the setMirror(),
setCloneAllBranches(), and setBranchesToClone() operations. Before
that commit, these could be set and reset independently and only in
call() it would be determined what exactly to do. Since that commit,
the last of these calls would determine the operation. This means
that the sequence
cloneCommand.setCloneAllBranches(true);
cloneCommand.setBranchesToClone(/* some list of refs */);
would formerly do a "clone all" giving a fetch refspec with wildcards
+refs/heads/*:refs/remotes/origin/*
which picks up new upstream branches, whereas since commit 6216b0de
individual non-wildcard fetch refspecs would be generated and new
upstream branches would not be fetched anymore.
Undo this behavioral change. Make the operations independently settable
and resettable again, and determine the exact operation only in call():
mirror=true > cloneAll=true > specific refs, where ">" means "takes
precedence over", and if none is set assume cloneAll=true.
Note that mirror=true implies setBare(true).

When fetching remote objects, WalkFetchConnection searches remote
packs in the order provided by WalkRemoteObjectDatabase:getPackNames.
Previously, for TransportAmazonS3, the packs were in no particular
order. This resulted in potential many extra calls to get pack idx
files.
This change modifies TransportAmazonS3 and AmazonS3 so that
getPackNames returns a list sorted with the most recently modified
packs first. In the case of fetching recent changes to a repo,
this dramatically reduces the number of packs searched and speeds
up fetch.
Note: WalkRemoteObjectDatabase::getPackNames does not specify
the order of the returned names.
Testing: did "mvn clean install" in root dir and all tests passed.
And manually constructed some S3 repos and using jgit.sh
confirmed that the freshest pack was checked first.
