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.

Add the following statistics
- cache hit count and hit ratio
- cache miss count and miss ratio
- count of successful and failed loads
- rate of failed loads
- load, eviction and request count
- average and total load time
Use LongAdder instead of AtomicLong to implement counters in order to
improve scalability.
Optionally expose these metrics via JMX, they are registered with the
platform MBean server if the config option jmx.WindowCacheStats = true
in the user or system level git config.

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.

This method was added in stable-5.6 after 5.6 RC1 was tagged. It's shown
as an API error when using 5.6.0 RC1 as the API baseline for master.
This suppression can be removed when 5.6 is released which will serve as
the API baseline for 5.7.

Passing int as an argument to String.format causes a warning:

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 actual usage. Where necessary extract the usage out to a local
variable.

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.

Instead of dropping a second exception, use try-with-resources so that
exception thrown by a hook is attached as a suppressed exception.
This removes a need of holding an exception that is thrown while
unpacking an incoming packfile.

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.

Unlike ReceivePack, the V0/V1 UploadPack response does not support
sideband except for the packfile parts. By sending an error in a
sideband packet, the JGit client says "Expected ACK/NACK, got: ...".
Use an error packet always. The recent Git clients will understand it
better than out-of-context sideband packets.

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.)
