All of the input lines passed to pre-push hook scripts must be properly
terminated by '\n', so that normal shell scripts like the git-supplied
pre-push.sample work properly, even when pushing just a single branch.

With the old code, hook scripts that use the following pattern didn't
process the last line, because 'read' has a non-zero exit status when
EOF is encountered:
  while read local_ref local_sha remote_ref remote_sha; do ... done

This breaks any scenario where native git (with LFS) clones a repository
(and thus installs the hook) and later on JGit is used to push changes.

Respect merge=lfs and diff=lfs attributes where required to replace (in
memory) the content of LFS pointers with the actual blob content from
the LFS storage (and vice versa when staging/merging).

Does not implement general support for merge/diff attributes for any
other use case apart from LFS.

If JGit built in LFS support is enabled for the current repository (or
user/system), any existing pre-push hook will cause an exception for the
time beeing, as only a single pre-push hook is supported.

Thus either native pre-push hooks OR JGit built-in LFS support may be
enabled currently, but not both.

Set missingOverrideAnnotation=warning in Eclipse compiler preferences
which enables the warning:

  The method <method> of type <type> should be tagged with @Override
  since it actually overrides a superclass method

Justification for this warning is described in:

  http://stackoverflow.com/a/94411/381622

Enabling this causes in excess of 1000 warnings across the entire
code-base. They are very easy to fix automatically with Eclipse's
"Quick Fix" tool.

Fix all of them except 2 which cause compilation failure when the
project is built with mvn; add TODO comments on those for further
investigation.

According to [1] the pre-push hook expects two parameters which provide
the name and location of the destination remote, if a named remote is
not being used both values should be the same.

We did set the first parameter to null in that case which caused
ProcessBuilder to throw a NullPointerException since its start() method
doesn't accept null arguments.

When the file <git-dir>/hooks/pre-push exists make sure that is is
executing during a push. The pre-push hook runs during git push, after
the remote refs have been updated but before any objects have been
transferred.

This hook uses the file .git/COMMIT_EDITMSG to receive and potentially
modify the commit message.

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.
