filelog: stop proxying flags() (API)

Per-revision storage flags are kinda a revlog-centric API. (Except for
the fact that changegroup uses the same integer flags as revlog does
and there's minimal verification that the server's flags map to the
client's storage flags - but that's another problem.)

The last user of flags() was in verify.py and that code was just moved
into revlog.py and is accessed behind the verifyintegrity() file
storage API.

Since there are no more consumers, let's drop the proxy and remove
the method from the file storage interface.

This commit only drops the dedicated API for reading a single
revision's storage flags: we still support reading and writing flags
through the bulk data retrieval and add revision APIs. And since
changegroups encode revlog integer flags over the wire, we'll always
need to support flags at some level. The removal of individual storage
flags may be too premature. But since flags() is now unused, I'd like
to see how far we can get without that dedicated API - especially
since it uses revision numbers instead of nodes.
