Building the jgit aggregator with Maven leads to a compiler level 1.6
for me, thereby failing the build. Multiple profiles specify
source/target level separately, but there seems no global setting.
Adding the global properties makes the jgit aggregator compile on my
system.

Several methods were protected when they were defined in BaseReceivePack
which has since been squashed into ReceivePack. Those methods no longer
need to be protected, and can now be private instead.

core.quotePath = false means that "bytes higher than 0x80 are not
considered "unusal" anymore"[1], i.e., they are not escaped. In
essence this preserves non-ASCII characters in path names in output.
Note that control characters and other special characters in the
ASCII range will still be escaped.
Add a new QuotedString.GIT_PATH_MINIMAL singleton implementing this.
Change the normal GIT_PATH algorithm to use bytes instead of characters
so it can be re-used. Provide a setter in DiffFormatter for the quoting
style so that an application can override the default, which is the
setting from the git config (and by default "true"). Use the new
QuotedString.GIT_PATH_MINIMAL when core.quotePath == false.

Some applications using JGit use their own repository caching. In
such applications, it may be needlessly inefficient to create new
submodule repositories from a SubmoduleWalk or in an IndexDiff. It
can be much more efficient to use an already cached repository
instance.
Provide a way to configure a SubmoduleWalk with a factory to create
BaseRepositoryBuilders to use to create repositories, and use it in
IndexDiff. Provide new IndexDiff.diff() operations that take such an
additional factory as parameter.
An application that caches Repository instances (for instance EGit)
can use a factory that provides builders that don't create a new
Repository instance but that return the already cached instance, if
one is available. Note that in such a case, the application may need
to be prepared to deal with IndexDiff.diff() also _closing_ the
obtained repository; if the application expects its cached Repository
instances to remain open while being cached, it'll have to use
Repository.incrementOpen() to prevent that the repository instance
gets closed.

IndexDiff would apply ignore mode ALL from .gitmodules to all remaining
submodules, and would ignore other settings from .gitignore and always
apply the setting defined on the IndexDiff instead. Correct that.
In canonical git the ignore setting from .gitmodules can also be
overridden by .git/config.[1] Implement that override in SubmoduleWalk.

Move the BaseReceivePack implementation back into ReceivePack. This is a
backward-incompatible change. For example, BaseReceivePack.FirstLine no
longer exists and cannot be referenced. However, most of the code
should just work by replacing BaseReceivePack with ReceivePack.
Although this is an API change, it only affects callers using JGit as a
server, and there are very few of those in the wild.

The getPackSize method will throw IllegalStateException if it is
called when the pack size is not set. This is the case for example
when the received commands are all DELETE and there is no pack.
Add a new method hasReceivedPack that can be called prior to calling
getPackSize, to avoid causing the IllegalStateException.

This ensures the measured filesystem timestamp resolution will be only

This avoids polluting hand-crafted user level config with
auto-configured options which might disturb in environments where
the user level config is replicated between different machines.
Add a jgit config as parent of the system level config. Persist
measured timestamp resolutions always in this jgit config and read it
via the user global config. This has the effect that auto-configured
timestamp resolution will be used by default and can be overridden in
either the system level or user level config.
Store the jgit config under the XDG_CONFIG_HOME directory following the
XDG base directory specification [1] in order to ensure that we have
write permissions to persist the file. This has the effect that each OS
user will use its jgit config since they typically use different
XDG_CONFIG_HOME directories.
If the environment variable XDG_CONFIG_HOME is defined the jgit config
file is located at $XDG_CONFIG_HOME/jgit/config otherwise the default is
~/.config/jgit/config.
If you want to avoid redundant measurement for different OS users
manually copy the values measured and auto-configured for one OS user to
the system level git config.

See [1] for JMH documentation and [2] how to use JMH in Eclipse.
The benchmarks pom currently cannot use the JGit parent pom due to an
ecj bug [3] regarding annotation processing. Hence for now do not
inherit from the JGit parent pom and copy the compiler plugin
configuration for javac from the parent pom.
After running the Maven build the benchmark can be run using Maven:
$ java -jar org.eclipse.jgit.benchmarks/target/benchmarks.jar
or in Eclipse by running the main method of the SimpleLruCacheBenchmark
class.
