Big tool rename.

As promised, this is the "big tool rename" patch.  The primary differences
since 0.99.6 are:

  (1) git-*-script are no more.  The commands installed do not
      have any such suffix so users do not have to remember if
      something is implemented as a shell script or not.

  (2) Many command names with 'cache' in them are renamed with
      'index' if that is what they mean.

There are backward compatibility symblic links so that you and
Porcelains can keep using the old names, but the backward
compatibility support  is expected to be removed in the near
future.

+
+Prepare each commit with its patch since our-head forked from upstream,
+one file per patch, for e-mail submission.  Each output file is
+numbered sequentially from 1, and uses the first line of the commit
+message (massaged for pathname safety) as the filename.
+
+When -o is specified, output files are created in that directory; otherwise in
+the current working directory.
+
+When -n is specified, instead of "[PATCH] Subject", the first line is formatted
+as "[PATCH N/M] Subject", unless you have only one patch.
+
+When --mbox is specified, the output is formatted to resemble
+UNIX mailbox format, and can be concatenated together for processing
+with applymbox.
