revset: make balanced addsets by orset() without using _combinesets() As scmutil.revrange() was rewritten to not use _combinesets(), we no longer need _combinesets().

revrange: evaluate all revset specs at once This provides an opportunity for revset to optimize given expressions. For example, "-r0 -r1 -r2" can be optimized to "_list(0 1 2)".

revset: add matchany() to construct OR expression from a list of specs This will allow us to optimize "-rREV1 -rREV2 ..." command-line options.

revset: split post-parsing stage from match() _makematcher() will be reused by new matchany(ui, specs, repo=None) function I'll add by the next patch.

filesets: ignore unit case in size() predicate for single value When specifying one plain value in size(), e.g. size(1k), fileset tries to guess the upper bound automatically (see the comment in _sizetomax()). It didn't ignore the specified unit's case, and so size("1 GB"), for example, produced this error: hg: parse error: couldn't parse size: 1 GB Let's do the same thing that util.sizetoint() does: .lower(). The two test lines without output just check that there are no parse errors.
