John Ericson 9bd437d4b4 fetchpatch: Add support for an arbitrary extra prefix
We still ensure the old and new ones start, respectfully, with `a/` and
`b/`. Use with `stripLen` to ensure tha the old `a/` and `/b` are gone
if a new prefix is added.

Dan Peebles dd8a42a224 fetchpatch: allow callers to specify postFetch sensibly
Before this fix, it seemed to be trying to merge our postFetch with the
patch normalization logic, but accidentally clobbering the whole thing
with the passed-in value.

Franz Pletz 7e8b3adb04 fetchpatch: add addPrefixes argument
Sometimes patches start without a leading prefix. We default to strip
one prefix or path component from patches (-p1) in the patchPhase in
stdenv.

As all patches should therefore be in this format, fetchpatch should
have an option to normalize patch paths. This commit introduces a new
argument to fetchpatch called addPrefixes that adds one patch prefix to
the old and new paths in a patch before putting it into the store.

fetchpatch: Allow to pass a postFetch attribute.
Comes in handy if we want to make additional modificiations to the
output file. While I wasn't sure whether to invoke the passed postFetch
directly before the patch or afterwards, I thought it would be better
afterwards because "postFetch of fetchpatch" at least to my intuition
would sound that after whatever "fetchpatch" does - it comes afterwards.

Vladimír Čunát 137eae0b55 Merge #2630: add and use fetchpatch
fetchpatch is fetchurl that determinizes the patch.
Some parts of generated patches change from time to time, e.g. see #1983 and
http://comments.gmane.org/gmane.linux.distributions.nixos/12815
Using fetchpatch should prevent the hash from changing.
