repository: define and use revision flag constants
Revlogs have a per-revision 2 byte field holding integer flags that
define how revision data should be interpreted. For historical reasons,
these integer values are sent verbatim on the wire protocol as part of
changegroup data.
From a semantic standpoint, the flags that go out over the wire are
different from the flags stored internally by revlogs. Failure to
establish this semantic distinction creates unwanted strong coupling
between revlog's internals and the wire protocol.
This commit establishes new constants on the repository module that
define the revision flags used by the wire protocol (and by some
internal storage APIs, sadly). The changegroups internals documentation
has been updated to document them explicitly. Various references
throughout the repo now use the repository constants instead of the
revlog constants. This is done to make it clear that we're operating
on generic revision data and this isn't tied to revlogs.
