Teach the FilterSpec serialization code about tree filters so they can
be communicated over the wire and understood by the server.
While we're here, harden the FilterSpec serialization code to throw
IllegalStateException if we encounter a FilterSpec that cannot be
expressed as a "filter" line. The only public API for creating a
Filterspec is to pass in a "filter" line to be parsed, so these should
not appear in practice.

OS X ships with a default /usr/bin/git that is just a wrapper that
at run-time delegates to the selected XCode toolchain, and that
prompts the user to install the XCode command line tools if not
already installed.
This is annoying for people who don't want to do so, since they'll
be prompted on each Eclipse start. Also, since on OS X the $PATH for
applications started via the GUI is not the same as the $PATH as set
via the shell profile, just using /usr/bin/git (which will normally
be found when JGit runs inside Eclipse) may give slightly surprising
results if the user has installed a non-Apple git and changed his
$PATH in the shell such that the non-Apple git is used in the shell.
(For instance by placing /usr/local/bin earlier on the path.) Eclipse
and the shell will use different git executables, and thus different
git system configs.
Therefore, try to find git via bash --login -c 'which git' not only
if we couldn't find it on $PATH but also if we found the default git
/usr/bin/git. If that finds some other git, use that. If the bash
approach also finds /usr/bin/git, double check via xcode-select -p
that an XCode git is present. If not, assume there is no git installed,
and work without any system config.

Using a fixed thread pool with unbounded LinkedBlockingQueue fixes the
RejectedExecutionException thrown if too many threads try to
concurrently determine filesystem attributes.
Comparing that to an alternative implementation using an unbounded

Include implementation version in jgit library. This version is used
by other products that depend on JGit, and built using Bazel and not
consume officially released artifact from Central or Eclipse own Maven
repository.
Most notably, in Gerrit Code Review JGit agent that was previously
reported as "unknown", is now reported as:
JGit/v5.8.0.202006091008-r-16-g14c43828d

In JGit 5.0, the FileTreeIterator was changed to skip ignored folders
by default. To catch tracked files inside ignored folders, the tree
walk needs to have a DirCacheIterator, and the FileTreeIterator has
to know about that DirCacheIterator via setDirCacheIterator(). (Or
the optimization has to be switched off explicitly via
setWalkIgnoredDirectories(true).)
Skipping ignored directories is an important optimization in some
cases, for instance in node.js/npm projects, where we'd otherwise
traverse the whole huge and deep hierarchy of the typically ignored
node_modules folder.
While all uses of WorkingTreeIterator in JGit had been adapted,
DiffFormatter was forgotten. To make it work correctly (again) also
for such cases, make it set up a WorkingTreeeIterator automatically,
and make sure the WorkingTreeSource can find such files, too. Also
pass the repository to the TreeWalks used inside the DiffFormatter
to pick up the correct attributes, filters, and line-ending settings.

The message "Too many commands" implies there is a hard limit on the
number of commands, which isn't the case. The limit is on the total
size of the received data, as explained in change I84317d396 which
introduced the configuration setting receive.maxCommandBytes:
shorter reference names allow for more commands, longer reference
names permit fewer commands per batch.
Change the message to:
Commands size exceeds limit defined in receive.maxCommandBytes

When iterating over the remote URLs to find one that matches "origin",
it always exits after the first iteration whether it has found the
remote or not. The break should be inside the conditional block so
that it exits when "origin" is found, otherwise continues to iterate
over the remaining remote URLs.

Add a test that confirms:
- No rename detector is initialized by default
- Rename detector is initialized after calling setDetectRenames(true)
- Rename limit and rename score have the default values 400 and
60, respectively. Note that there are no constants for these values
so the test hard codes them.

Currently we're buffering the inflated bitmap entry in
BasePackBitmapIndex to optimize running time. However, this will use
lots of memory during the creation of the pack bitmap index file.
And change 161456, which rewrote the entire getBitmap method, increased
the fetch latency significantly.
This commit introduces getBitmapWithoutCaching method which is used in
the pack bitmap index file creation only and aims to save memory during
garbage collection and not increase fetch latency.

We can either
- try moving the file and, in case the target directory doesn't exist,
handle the NoSuchFileException this raises to create the target
directory
- or we always first test if the target directory exists and create it
in case it is missing
On my Mac this yields
Benchmark Mode Cnt Score Error Units
FileMoveBenchmark.moveFileToExistingDir avgt 5 196.490 ± 15.194 us/op
FileMoveBenchmark.moveFileToExistingDirExists avgt 5 223.217 ± 54.816 us/op
FileMoveBenchmark.moveFileToMissingDir avgt 5 332.169 ± 43.871 us/op
FileMoveBenchmark.moveFileToMissingDirExists avgt 5 303.815 ± 137.568 us/op
This means if the target directory of the move already exists the
first strategy is faster by around 25 us/op otherwise the second one
is faster by around 30 us/op. Which one is favorable depends on the
average probability that the target directory exists in real world
scenarios.

The current mechanism for updating the unpack error handler requires
that the error handler is replaced entirely, including communicating
the error to the user. Adding a getter means that delegating
implementations can be constructed so that the error can be processed
before sending to the user, for example for logging.

- The code to move the file is repeated. Split it out into a
utility method.
- Remove the catch block for AtomicMoveNotSupportedException which
is redundant because it's handled in exactly the same way as the
IOException further down. The only exception we need to explicitly
handle differently in this block is NoSuchFileException.
- Improve the comments.

If a hunk does not apply at the position stated in the hunk header
try to determine its position using the old lines (context and
deleted lines).
This is still a far cry from a full git apply: it doesn't do binary
patches, it doesn't handle git's whitespace options, and it's perhaps
not the fastest on big patches. C git hashes the lines and uses these
hashes to speed up matching hunks (and to do its whitespace magic).
