Simplify ReftableCompactor

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.

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.

Java GC evicts all SoftReferences when the used heap size comes close to
the maximum heap size. This means peaks in heap memory consumption can
flush the complete WindowCache which was observed to have negative
impact on performance of upload-pack in Gerrit.
Hence add a boolean option core.packedGitUseStrongRefs to allow using
strong references to reference packfile pages cached in the WindowCache.
If this option is set to true Java gc can no longer flush the
WindowCache to free memory if the used heap comes close to the maximum
heap size. On the other hand this provides more predictable performance.

Using exceptions during normal operations - for example with the
desire of expanding an array in the failure case - can have a
severe performance impact. When exceptions are instantiated,
a stack trace is collected. Generating stack trace can be expensive.
Compared to that, checking an array for length - even if done many
times - is cheap since this is a check that can run in just a
handful of CPU cycles.

This gives a chance to handle an exception for a user. For example, when
an IOException is thrown while executing
`walk.parseAny(cmd.getNewId())`, it's always handled as
REJECTED_MISSING_OBJECT. However, IOException can mean a Git storage IO
error. By introducing an error handler class, a user can add a custom
error handler for these cases.

Move exception handling code to the caller side. This is a preparation
for adding a custom error handler that is similar to UploadPack.
Note that `catch (Throwable t)` will not affect the exception spec since
Java will do an analysis of rethrown exceptions. See
https://docs.oracle.com/javase/8/docs/technotes/guides/language/catch-multiple.html.

This removes a raw IOException at one level. Later we'll add a custom
exception handling mechanism like UploadPack.

This partially reverts Ic6bb5e66. It made private some methods in
ReceivePack that were protected before. At least two of those methods
(#init and #receivePackAndCheckConnectivity) are used by out-of-tree
subclasses for tracing and testing.
Make ReceivePack#init() and ReceivePack#receivePackAndCheckConnectivity
protected again to allow tracing and testing.

When a conflicting file was blamed, JGit would not identify lines
coming from the merge parents. The main cause for this was that
Blame and BlameCommand simply added the first DirCacheEntry found
for a file to its queue of candidates (blobs or commits) to consider.
In case of a conflict this typically is the merge base commit, and
comparing a auto-merged contents against that base would yield
incorrect results.
Such cases have to be handled specially. The candidate to be
considered by the blame must use the working tree contents, but
at the same time behave like a merge commit/candidate with HEAD
and the MERGE_HEADs as parents. Canonical git does something very
similar, see [1].
Implement that and add tests.
I first did this for the JGit pgm Blame command. When I then tried
to do the same in BlameCommand, I noticed that the latter also
included some fancy but incomplete CR-LF handling. In order to
be able to use the new BlameGenerator.prepareHead() also in
BlameCommand this CR-LF handling was also moved into BlameGenerator
and corrected in doing so.
(Just considering the git config settings was not good enough,
CR-LF behavior can also be influenced by .gitattributes, and even
by whether the file in the index has CR-LF. To correctly determine
CR-LF handling for check-in one needs to do a TreeWalk with at
least a FileTreeIterator and a DirCacheIterator.)

When this class was split from DfsReftableDatabase in commit
2b1e942729 (reftable: split off generic
code from DFS code, 2019-09-26), we forgot to carry over the license
header.

Reftable-enabled repositories don't have a file called HEAD. Check for
reftable/ instead.
This fixes repository creation on reftable in Gerrit.
