This reverts commit b5e764abd2.
PlotWalk uses the TopoSortGenerator, which is causing problems for EGit users
who rely on the emission of commits being somewhat based on date as in the
previous topo-sort algorithm.

This reverts commit e102bbed99.
Resolving the hostname comes with a performance penalty. We no longer
store the timestamp resolution in the global git config which might be
copied around to other machines but in a dedicated jgit config meant for
automatically determined options like timestamp resolution. Hence there
is no strong reason anymore to have a hardware specific identifier in
the subsection name of file timestamp resolution options.

An indexOf or lastIndexOf call with a single letter String can be
made more performant by switching to a call with a char argument.

As a side-effect of this change, we no longer need to suppress the

The Java Language Specification recommends listing modifiers in
the following order:
1. Annotations
2. public
3. protected
4. private
5. abstract
6. static
7. final
8. transient
9. volatile
10. synchronized
11. native
12. strictfp
Not following this convention has no technical impact, but will reduce
the code's readability because most developers are used to the standard
order.
This was detected using SonarLint.

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.
