This will change the behavior in the CLI to resemble that of C-Git more
closely by printing the stderr of the hooks to the CLI stderr
independently of the exit code of the hook.
This is also useful for the corresponding EGIT-Change, which will add
the ability to show the hook output in eclipse.
With this also the stderr can be shown even if the exit code is 0.

Git log supports the exclude pathspec, which allows for excluding paths
from the log command. JGit only supports adding paths to the log
command. See the following StackOverflow question for details:
https://stackoverflow.com/questions/59143934/java-jgit-how-to-get-git-
commits-not-affecting-certain-directories
This commit adds an excludePath() method to the log command. It does not
yet support regex or glob wildcards.

Most of these are already suppressed, but there are a couple that are
not. Add suppressions for those.
For the existing ones, move the suppression scope from the method to

The reftable format supports fast inverse (SHA1 => ref) queries.
If the ref database does not support fast inverse queries, it may be
advantageous to build a complete SHA1 to ref map in advance for
multiple uses. To let applications decide, this function indicates
whether the inverse map is available.

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.)

The checker is creating a new bitmap per branch leading to excessive
memory consumption. For the reachability check one bitmap with the
reachability of all branches aggregated is enough.
Build the reachability bitmap with a filter. The filter itself uses it
to emit only commits not reached before and the caller to check what
targets have been reached already.
BitmapCalculator is not required anymore.

The ref points to an ObjectId that then is translated into a RevCommit.
This translation can be costly and with the incremental reachability
check is probably not needed for most of the elements.
Delay the translation from ObjectId to RevCommit to when it is needed.
Use Streams, that have the laziness built-in, all the way from Ref to
RevCommit.
This should reduce the latency for reachability checks over big sets of
references.

Preparatory change. Converting ObjectIds to RevCommits is potentially
expensive and in the incremental reachability check, it is probably not
required for all elements in the collection.
Pass a Stream to the reachability checker. In the follow up we make
the conversion from ObjectId to RevCommit in the stream (i.e. on
demand). This should reduce the latency of reachability checks over big
sets of references.

UploadPack needs to check if object ids that weren't advertised before
are reachable from the references visible to the user. In the
bitmap-based reachability check, this is done incrementally: checking
against one reference, if anything remaining adding a second and so on.
It is more efficient to check first more common references (e.g. refs/heads/*)
Sort the references for the reachability checker. This should solve the
connectivity earlier and require less bitmap creation and less memory.

Reftable is a binary, block-based storage format for the ref-database.
It provides several advantages over the traditional packed + loose
storage format:
* O(1) write performance, even for deletions and transactions.
* atomic updates to the ref database.
* O(log N) lookup and prefix scans
* free from restrictions imposed by the file system: it is
case-sensitive even on case-insensitive file systems, and has
no inherent limitations for directory/file conflicts
* prefix compression reduces space usage for repetitive ref names,
such as gerrit's refs/changes/xx/xxxxx format.
FileReftableDatabase is based on FileReftableStack, which does
compactions inline. This is simple, and has good median performance,
but every so often it will rewrite the entire ref database.
For testing, a FileReftableTest (mirroring RefUpdateTest) is added to
check for Reftable specific behavior. This must be done separately, as
reflogs have different semantics.
Add a reftable flavor of BatchRefUpdateTest.
Add a FileReftableStackTest to exercise compaction.
Add FileRepository#convertToReftable so existing testdata can be
reused.
