tags: change format of tags cache files
.hgtags fnodes are now written to a shared cache file. They don't need
to exist in the per-filter tags cache files. Stop writing them.
The format of the tags cache file has changed in a backwards
incompatible way. This should be acceptable, as we just established
per-filter tags cache files and no client should have per-filter tags
cache files that will need to be read. So no backwards compatbility
concern is present.
The new format has a single header line followed by resolved tags
entries.
The header line is similar to the old first line with a major
difference: we now compute and store a hash of the filtered revisions.
Before, if the set of filtered revs changed, we may return incorrect
results. We now detect that.
A test for verifying filtered rev change is handled properly has been
added.
