Was replaced by FastIgnoreRule in 3.6

The path matcher should not fail if the rule ends with trailing slash,
target pattern does not ends with the slash and the "assumeDirectory"
flag is set.

E.g. */bin/ should also match a/bin if this pattern is threated as
directory by WorkingTreeIterator (FileMode.TREE).

The old code/tests have never tested directory rules with patterns
*without* trailing slashes but with the "assumeDirectory" flag set.
Unfortunately this is exactly what WorkingTreeIterator does... The tests
are changed to test *both* cases now (with trailing slash and without)
if the target pattern has trailing slash (represents directory).

To improve ignore parser performance we can avoid using java.util.regex
code on simple wildcard patterns with leading or trailing asterisk. As
those patterns represent a majority of ignore rules, the index diff
performance can be drastically increased on huge repository with lot of
ignore rules.

JGit style is to import exactly the classes required, and never
to use "import foo.*" as the foo package could add new classes
in the future which are conflicting/confusing with the imports
already used by a source file.

The current IgnoreRule/FileNameMatcher implementation scales not well
with huge repositories - it is both slow and memory expensive while
parsing glob expressions (bug 440732). Addtitionally, the "double star"
pattern (/**/) is not understood by the old parser (bug 416348).

The proposed implementation is a complete clean room rewrite of the
gitignore parser, aiming to add missing double star pattern support and
improve the performance and memory consumption.

The glob expressions from .gitignore rules are converted to Java regular
expressions (java.util.regex.Pattern). java.util.regex.Pattern code can
evaluate expression from gitignore rules considerable faster (and with
less memory consumption) as the old FileNameMatcher implementation.

The matcher has to be reset before using it, as was already done in the
other cases.

Patterns containing only a trailing slash have to be treated
as "global" patterns. For example: "classes/" matches "classes"
as well as "dir/classes" directory.

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

This patch adds ignore compatibility to jgit. It encompasses
exclude files as well as .gitignore. Uses TreeWalk and
FileTreeIterator to find nodes and parses .gitignore
files when required. The patch includes a simple cache that
can be used to save results and avoid excessive gitignore
parsing.
