revset: changed ancestors revset to return lazy generators

This will not improve revsets like "::tip" but will do when that gets
intersected or substracted with another revset.

Performance Benchmarking:

$ time hg log -qr "draft() and ::tip"
...

real  0m3.961s
user  0m3.640s
sys 0m0.313s

$ time ./hg log -qr "draft() and ::tip"
...

real  0m1.080s
user  0m0.987s

Mercurial's documentation is kept in reStructuredText format, which is
a simple plain text format that's easy to read and edit:

It's also convertible to a variety of other formats including standard
UNIX man page format and HTML. You'll need to install Docutils:
