/tmp is a symbolic link and some tests break when the path
gets canonicalized by JGit or Jetty. Allow Jetty to serve
symlinks by setting init parameter "aliases" to true [1].

Currently, the offset can only be retrieved by ObjectId or iterating all
of the entries. Add a method to lookup the offset by position in the
index sorted by SHA1.

I was seeing output like this while running The BFG:

Updating references:    200% (374/187)

...issue sneaked in with 5cf53fda I think.

The update call is also moved to the end of the loop, as update() is
only supposed to be called after work has been done ("Denote that some
work units have been completed").

`pwd`/target is only valid in Maven Reactor builds where Maven
has moved into the project directory and created a target for
the build output. Most other build systems do not use "target"
and may not even perform a directory change between test suites.

Rewrite LocalDiskRepositoryTestCase's temporary directory code
to use the system specified location and create new unique names.
This prevents fixes between concurrently running tests and allows
the caller to specify the root using java.io.tmpdir.

Update the surefire command lines to use target within each project as
the system temporary directory during unit testing, preventing JGit's
own test suite from writing to /tmp or somewhere like C:\tmp.

Instead of re-reading all refs after each update, execute
the deletes first, then read all refs once and perform
the check for conflicting ref names in memory.

Only on Windows the rename operation which renames temporary Packfiles
(and index-files and bitmap-files) sometime fails. This happens only
when renaming a temporary Packfile to a Packfile which already exists.
Such situations occur if you run GC twice on a repo without modifying
the repo inbetween.

In such situations there was bug in GC which led to a corrupted repo
whithout any packfiles anymore. This commit fixes the problem by
introducing a utility method which renames a file and throws an
IOException if it fails. This method also takes care to repeat a
failing rename if our FS class has found out we are running on a
platform with a unreliable File.renameTo() method.

I am searching for a better solution because even with this utility
method in hand a GC on a already GC'ed repo will fail on Windows. But
at least with this fix we will not produce corrupted repos anymore.

With JGit it is possible to write reflog entries where new objectid and
old objectid is null. Such reflogs cause FileRepository GC to crash
because it doesn't expect the new objectid to be null. One case where
this happened is in Gerrit's allProjects repo. In the same way as we
expect the old objectid to be potentially null we should also ignore
null values in the new objectid column.

This breaks all existing callers once. Applications are not supposed
to build against the internal storage API unless they can accept API
churn and make necessary updates as versions change.
