The class FS_Win32 was always trying out to create a temporary symlink
in order to find out whether symlinks are supported. FS_Win32_Cygwin was
overwriting this method and always returned true. But when the user
running JGit does not have administrative rights then the creation of
symlinks is forbidden even if he is running on FS_Win32_Cygwin. A lot of
tests failed only on the Windows platform because of this. It was
correctly detected that FS_Win32_Cygwin is the filesystem abstraction to
be used but creation of symlinks always failed because of lacking
privileges of the user running the tests.

This fix teaches FS_Win32_Cygwin to behave like FS_Win32 and to test
whether symlinks can be created in order to find out whether symlinks
are supported.

As we moved minimum Java version to 7 we don't need a separate bundle
and feature for JGit features depending on Java 7 anymore.

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
