revset: make descendants() lazier
Previously descendants() would force the provided subset to become a set. In
the case of revsets like '(%ld::) - (%ld)' (as used by histedit) this would
force the '- (%ld)' set to be evaluated, which produced a set containing every
commit in the repo (except %ld). This takes 0.6s on large repos.
This changes descendants to trust the subset to implement __contains__
efficiently, which improves the above revset to 0.16s. Shaving 0.4 seconds off
of histedit.

This commit removes the final revset related perf hotspot from histedit.
Combined with the previous two patches, they shave a little over 3 seconds off
histedit on large repos.
contrib/synthrepo: return None to delete files on commit, don't raise IOError
The internal commit API was changed in
650b5b6e75ed to expect None from the
filectx function when a file is to be deleted, not an IOError. This change
keeps synthrepo up-to-date.
dockerrpm: create a yum/dnf repo from the generated rpms
This gives "PPA" functionality where users easily can stay uptodate with latest
nightly build.
