Add some tests which make sure that the diff algorithm really behaves in the
promised O(N*D) manner. This tests compute diffs between multiple big chunks
of data, measure time for computing the diffs and fail if the measured times
are off O(N*D) by more than a factor 10

This change only fixes warnings of the eclipse build regarding missing javadocs.
Some comments where just missing, so they have been added. Other comments where
at the wrong (from eclipse point of view) place, so eclipse was complaining.
Also two method which existed for debugging purposes have been removed to get
rid of Eclipse warngins about unused code.

  Fixed MyersDiff to be able to handle more than 100k

MyersDiff was crashing with ArrayIndexOutOfBoundsException when
diffing huge files. This was because the snake data (begin and
end position while processing chunks of the text) was sequeezed
into a single int. But with longer texts to diff these values
exceeded the range of java int values. It is fixed by squeezing
the two ints into a long and by adding the LongList helper
class.

My Galileo eclipse was complaining about unneeded import statements and
how static methods have been accessed in Diff.java. There was also one method
call which could be removed because he had no sideeffects and the return value
was not used. I fixed this so that there are no warnings anymore.

Myers' algorithm is the standard way to generate diff scripts in
an efficient manner (especially memory-wise).

The source contains extensive documentation about the principal
ideas of the algorithm.

This removes one of the few remaining dependencies on AWTAuthenticator
from the core library.  For the most part the interface is identical to
the prior main method.  The jgit-pgm Main class already sets up the
HTTP proxy and authenticator for us, so we don't need to do that in
our new run method.

This test doesn't work because it requires a pack file which we have
lost to the ages.  We couldn't include it because the pack was actually
a copy of the GPL'd C git.git project, and was there to test some sort
of corner case that the test never documented properly.

* changes:
  Add support for logAllRefUpdates configuration parameter

Honor the configuration parameter core.logAllRefUpdates when writing
reflogs.  Instead of writing reflog entries always only write
reflogs if this parameter is set to true or if the corresponding
file in the <git-dir>/logs directory already exists. In other words:
if you are updating a ref and this parameter is set to false and
there is no file corresponding to your ref in the <git-dir>/logs
folder then no reflog will be written.

This is a fix for the issue http://code.google.com/p/egit/issues/detail?id=4

There is no longer any value in keeping track of things we need to
implement in a file in the top level of the source code.  Time has
proven we don't keep it current, as some of these features are
already implemented, and some are still being worked on.

Worse, many of these items were for the EGit plugin, which has no
relationship to JGit.

I somehow missed that SUBMITTING_PATCHES referenced the older "send

few years of the JGit project's life.  Now that we are hosted under
the Eclipse Foundation umbrella we need to follow their IP process
for all contributions.

This allows SwingGraphPanes to be reused by simply clearing and
re-filling. Requires RevObjectList initialization to not call clear()
from its constructor, because this will lead PlotCommitList.clear()
to be called before all variables have been initialized.

This script can be executed by a developer to download and graft
on the old JGit history, from before we moved the project to the
eclipse.org namespace and the Eclipse Foundation servers.

Executing this script is only necessary if you need to run log or
blame past the migration boundary, and isn't always recommended when
it comes to pushing objects to a remote server.  As mentioned in the
script, it is best to use a specialized repository with this graft,
not your main work repository.
