localrepo: add sparse caches...

localrepo: add sparse caches The sparse extension maintains caches for the sparse files to a signature and a signature to a matcher. This allows the sparse matchers to be resolved quickly, which is apparently something that can occur in loops. This patch ports the sparse caches to the localrepo class pretty much as-is. There is potentially room to improve the caching mechanism. But that can be done as a follow-up. The default invalidatecaches() now clears the relevant sparse cache. invalidatesignaturecache() has been moved to sparse.py.
