Resend of the complete patch serie (again next).

Patch 1-3 are unchanged.

Patch 4 now only generates the links, if they are enabled.
The header contains a new link to show/hide the links.
The state is remembered via a cookie across pages.

Patch 5 is the foundation for showing the base/diff links
in an other color.

PS:
I develop the patches via StGit. If you think that I should publish them
in a different way, please tell me.

* [PATCH 1/5] gitweb: Support comparing blobs with different names

Currently, blobdiff can only compare blobs with different file
names, if no hb/hpb parameters are present.

This patch adds support for comparing two blobs specified by any
combination of hb/f/h and hpb/fp/hp.
