DirCacheCheckout and CanonicalTreeParser cooperate. CanonicalTreeParser
can detect malformed, potentially malicious tree entries and sets a
flag, while DirCacheCheckout refuses to work with such paths.

Malicious tree entries are ".", "..", ".git" (case insensitive), any
name containing '/' and (on Windows '\') and also (on Windows)
any paths ending in a combination of '.' or space or containing a ':'.
We also forbid all special names like "con" etc on Windows.

Some of the test can execute on any platform by enabling partial
platform emulation.

A new runtime exception, InvalidPathException, is introduced. For
backwards compatibility it extends InvalidArgumentException.

Instead of using the locale from the SystemReader we let the
SystemReader create the date formats without passing the locale.

These settings are stored in <prefix>/etc/gitconfig. The C Git
binary is installed in <prefix>/bin, so we look for the C Git
executable to find this location, first by looking at the PATH
environment variable and then by attemting to launch bash as
a login shell to find out.

LockFile.commit fails if another thread concurrently reads
the base file. The problem is fixed by retrying the rename
operation if it fails.

This move isolates all of the local file specific implementation code
into a single package, where their package-private methods and support
classes are properly hidden away from the rest of the core library.

Because of the sheer number of files impacted, I have limited this
change to only the renames and the updated imports.

On Windows, FS_Win32_Cygwin has been used if a Cygwin Git installation
is present in the PATH. Assuming that the user works with the Cygwin
Git installation may result in unnecessary overhead if he actually
does not.

Applications built on top of jgit may have more knowledge on the
actually used Git client (Cygwin or not) and hence should be able to
configure which FS to use accordingly.

Since cc905e7d4b "Make Repository.getConfig aware of changed config"
its invalid to have a null result from FileBasedConfig.getFile(), as
the path is used to stat the location on disk before returning the
Config object from Repository.getConfig().

Mock out the isOutdated() method to return false all of the time
in the mock test environment, so we don't crash with an NPE when
this mock user configuration is being called.

Instead do nothing.  For now, save() will fail and the config
file is set to null, which may surprise some calling tests.

The LocalDiskRepositoryTestCase class is derived from the current
RepositoryTestCase code and is meant for application (or our own)
tests to subclass and access temporary repositories on the local
client disk.

Per CQ 3448 this is the initial contribution of the JGit project
