This patch serves two purposes. Firstly it unifies the concept of mirrors into
PREMIRRORS and MIRRORS. PREMIRRORS are tried before the SRC_URI defined in the
recipe whereas MIRRORS are tried only if that fails.
The tarball stash was conceptually inline with a PREMIRROR only with special
handling within the wget fetcher and therefore only worked with certain
fetch types.
Secondly the patch removes the need for individual fetch implementations to
worry about mirror handling.
With this patch, the base fetch implementation will first try to use a
PREMIRROR to fetch the desired object, if this fails the native fetch method
for the object will be tried and if this fails will try to fetch a copy from
one of the MIRRORS.

The Mercurial fetcher right now will fail when used to incrementally
fetch an update to a local clone of a repository already fetched at
some prior revision. The culprit is the sequence:
hg pull -r <rev>
hg update -C <rev>
A subtlety in the way that Mercurial stores its tags (in a normally
version-controlled file called .hgtags) has the side-effect that a
repository fetched at a tag "foo" will not actually contain a
new-enough copy of the .hgtags file to be self-aware of the foo tag's
existence.
The solution is just to get all the changesets in the repository on
incremental upgrades, so that the following "hg update" will be able
to resolve the tag.
