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.

The censor system allows retroactively removing content from
files. Actually censoring a node requires using the censor extension,
but the functionality for handling censored nodes is partially in core.
Censored nodes in a filelog have the flag ``REVIDX_ISCENSORED`` set,
and the contents of the censored node are replaced with a censor
tombstone. For historical reasons, the tombstone is packed in the
filelog metadata field ``censored``. This allows censored nodes to be
(mostly) safely transmitted through old formats like changegroup
versions 1 and 2. When using changegroup formats older than 3, the
receiver is required to re-add the ``REVIDX_ISCENSORED`` flag when
storing the revision. This depends on the ``censored`` metadata key
never being used for anything other than censoring revisions, which is
true as of January 2017. Note that the revlog flag is the
authoritative marker of a censored node: the tombstone should only be
consulted when looking for a reason a node was censored or when revlog
flags are unavailable as mentioned above.
The tombstone data is a free-form string. It's expected that users of
censor will want to record the reason for censoring a node in the
tombstone. Censored nodes must be able to fit in the size of the
content being censored.
