Stepping past the '.git' entry with `fti.next(1)` is unnecessary and in
fact a bug, as the subsequent access to FileTreeIterator is past it's
end-of-file - it has only 1 valid entry ('link').
This bug is only visibly exposed in certain environments depending on the
(unguaranteed) return order of `java.io.File.listFiles()`. On my box
FileTreeIteratorJava7Test would fail consistently for these 3 tests:
* testSymlinkActuallyModified
* testSymlinkNotModifiedThoughNormalized
* testSymlinkModifiedNotNormalized
They all failed in the same way:
testSymlinkActuallyModified(org.eclipse.jgit.treewalk.FileTreeIteratorJava7Test) Time elapsed: 0.063 sec <<< ERROR!
org.eclipse.jgit.api.errors.JGitInternalException: /home/roberto/development/jgit/org.eclipse.jgit.java7.test/target/jgit_test_9202429389985749040_tmp

Theses tests are all working with a small repo that has just two entries:
'.git' and 'link' (a symbolic link that's being tested on). `listFiles()`
is called by FileTreeIterator to get a preliminary list of FileEntry
objects:
https://github.com/eclipse/jgit/blob/6d724dcd/org.eclipse.jgit/src/org/eclipse/jgit/treewalk/FileTreeIterator.java#L139
Whether your tests appeared to pass or fail was dependent on the returned
order of files from `listFiles()`:
* ['.git', 'link'] - PASS (Eclipse Hudson appears to get this ordering)
* ['link', '.git'] - FAIL (My env, Ubuntu 14.04/Java 1.7.0_55)
The tree-iterator passes the resulting `FileEntry`s to it's init() method:
https://github.com/eclipse/jgit/blob/6d724dcd/org.eclipse.jgit/src/org/eclipse/jgit/treewalk/WorkingTreeIterator.java#L639-L665
... where a count of valid entries is made (`entryCnt`), the 'invalid'
entries (like'.git') being left in the hinterland of the `entries` array.
The rearrangement in the entries array for our tests looks like this:
* ['.git', 'link'] -> ['link', 'link']
* ['link', '.git'] -> ['link', '.git']
In both cases, `entryCnt` is set to 1, meaning that the _valid_ portion of
the iterator is the same (ie ['link']), but that the portion after EOF,
which we reach by calling `fti.next(1)`, is _different_ depending on your
environment. The entry used by the iterator at that point will be either
'link' (if you're lucky) or '.git', which will blow up the test.
Note that somewhat ironically, the 'self-check' assertions don't catch
this bug, as 'path' data is only parsed _before_ EOF - so
`fti.getEntryPathString()` returns the string "link" (and the assertion
passes) regardless of whether you're about to read the '.git' entry or not.

It's strange that we have that member since it is not so clear
when it it set or not.

According to Win32 API, you need to specificy whether a symlink
points to a file or directory. These tests suggests a symlink created
for a file, can actually point to a directory. We can also create the
link before the target exists, so at least in this respect Windows
symbolic links appears to work as POSIX links.
On POSIX systems these tests have no relevance.

Test that the file mode of a file is the one expected before and after a
checkout. Tests between symlink and file, symlink and folder, symlink
and missing.

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 dash signing plugin has been retired hence we need to update our
build to use the CBI jarsigner plugin for signing build results.
Pack test classes to enable signing them.
Also re-enable pack200 for bundle org.eclipse.jgit.
WORKAROUND: there is no easy way to run tests with maven-surefire-plugin
from signed test-jar so for a quick workaround we will have to add a
build step on Hudson so that we can run tests before signing:
- first step will do "clean, verify" to compile and run tests
- second step will do "install, deploy" with profile "eclipse-sign" and
use -DskipTests=true to skip tests since they would hit a
SecurityException when unsigned test classes are in same package as
signed classes under test
- third step will do "clean, install, deploy" on packaging reactor to
build features and p2 repository with profile "eclipse-sign" to sign
and pack200 all bundles.
TODO: Tycho doesn't suport picking up pack200 artifacts via
pomDependencies hence we need to find a way to copy them manually and
use tycho-extra's tycho-p2-extras-plugin:publish-features-and-bundles
to generate the missing p2 metadata.

DirCacheCheckout had a bug when the parentdirectory of a worktree was a
symlink. DirCacheCheckout was deleting those symlinks under certain
conditions. This was fixed in I81735ba0394ef6794e9b2b8bdd8bd7e8b9c6460f
without a test because previously it was hard to setup tests containing
symlinks.

warning lead to complaints.
If fixing is not wanted, disable it instead.
