revset: add optional offset argument to limit() predicate

It's common for GUI or web frontend to fetch chunk of revisions per batch
size. Previously it was possible only if revisions were sorted by revision
number.

  $ hg log -r 'limit({revspec} & :{last_known}, 101)'

So this patch introduces a general way to retrieve chunk of revisions after
skipping offset revisions.

  $ hg log -r 'limit({revspec}, 100, {last_count})'

This is a dumb implementation. We can optimize it for baseset and spanset
later.

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:

Use the Makefile in this directory to generate the man and HTML pages.
