HFS is case insensitive hence expecting it to return the result for case
sensitive filesystem doesn't work.

This introduces the background plumbing necessary to run git hooks from
JGit. This implementation will be OS-dependent as it aims to be
compatible with existing hooks, mostly written in Shell. It is
compatible with unix systems and windows as long as an Unix emulator
such as Cygwin is in its PATH.

Buck does not create a target directory for the build output, this
is Maven specific and the project unit tests should not rely on it.

Instead follow the pattern used by org.eclipse.jgit.test which is to
create a temporary directory in the system temporary folder, and
configure the Maven surefire plugin to use the target directory.

The hamcrest library has moved things around. This problem applies only
to the test, not plugin runtime.

The most important difference is that in Java7 we have symbolic links
and for most operations in the work tree we want to operate on the link
itself rather than the link target, which the old File methods generally
do.

We also add support for the hidden attribute, which only makes sense
on Windows and exists, just since there are claims that Files.exists
is faster the File.exists.

A new bundle is only activated when run with a Java7 execution
environment. It is implemented as a fragment.

Tycho currently has no way to conditionally include optional features
based on the java version used to run the build, this means with this
change the jgit packaging build always needs to be run using java 7.

Depending on the order in which items are traversed for RECURSIVE, an
empty directory may come first before detecting that there is a file and
aborting.

This fixes it by traversing files first.

This reverts commit 7aa54967a2.
The unit test dependend upon the specific order of names that
listFiles() returned members in. The order is completely undefined
and may differ even on different versions of Linux based systems.

A proper unit test for this code would have considered both cases,
where the deletion function was able to remove an empty subdirectory,
or fail to remove a subdirectory because a file was still present
within. This is not such a test.

Unlike the OS or Java rename this method will (on *nix) try (on Windows)
replace the target with the source provided the target does not exist,
the target does exist and is a file, or if it is a directory which only
contains directories. In the latter case the directory hierarchy will be
deleted.
If the initial rename fails and the target is an existing file the the
target file will be deleted first and then the rename is retried.

The new option EMPTY_DIRECTORIES_ONLY will make delete() only delete
empty directories. Any attempt to delete files will fail. Can be
combined with RECURSIVE to wipe out entire tree structures and
IGNORE_ERRORS to silently ignore any files or non-empty directories.

Eclipse has some problem re-running single JUnit tests if
the tests are in Junit 3 format, but the JUnit 4 launcher
is used. This was quite unnecessary and the move was not
completed. We still have no JUnit4 test.

This completes the extermination of JUnit3. Most of the
work was global searce/replace using regular expression,
followed by numerous invocarions of quick-fix and organize
imports and verification that we had the same number of
tests before and after.

- Annotations were introduced.
- All references to JUnit3 classes removed
- Half-good replacement for getting the test name. This was
  needed to make the TestRngs work. The initialization of
  TestRngs was also made lazily since we can not longer find
  out the test name in runtime in the @Before methods.
- Renamed test classes to end with Test, with the exception
  of TestTranslateBundle, which fails from Maven
- Moved JGitTestUtil to the junit support bundle
