Hooks are now obtained via a convenient API like git commands, and
callers don't have to check for their existence.
The pre-commit hook has been updated accordingly.

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.

Java normalizes paths to NFC, but other source may not, e.g Eclipse.

On Windows the length reported by FileAttributes is the size
of the target file (a bug, I guess) rather than the link,
so we read the linke and look at the length of the link instead.

To get symlink support you typically need to run as administrator.

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.
