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.

basic commands:
add add the specified files on the next commit
annotate show changeset information by line for each file
clone make a copy of an existing repository
commit commit the specified files or all outstanding changes
diff diff repository (or selected files)
export dump the header and diffs for one or more changesets
forget forget the specified files on the next commit
init create a new repository in the given directory
log show revision history of entire repository or files
merge merge another revision into working directory
pull pull changes from the specified source
push push changes to the specified destination
remove remove the specified files on the next commit
serve start stand-alone webserver
status show changed files in the working directory
summary summarize working directory state
update update working directory (or switch revisions)
(use "hg help" for the full list of commands or "hg -v" for details)
