revrange: build balanced tree of addsets from revisions (issue4565)

This reduces the stack depth from O(n) to O(log(n)). Therefore, repeated
-rREV options will never exceed the Python stack limit.

Currently it depends on private revset._combinesets() function. But at some
point, we'll be able to drop the old-style parser, and revrange() can be
completely rewritten without using _combinesets():

  trees = [parse(s) for s in revs]
  optimize(('or',) + trees)  # combine trees and optimize at once
  ...

Blockers that prevent eliminating old-style parser:

 - nullary ":" operator
 - revrange(repo, [intrev, ...]), can be mapped to 'rev(%d)' ?
 - revrange(repo, [binnode, ...]), should be banned ?

Mercurial
=========

Mercurial is a fast, easy to use, distributed revision control tool
for software developers.

Basic install:

 $ make            # see install targets
 $ make install    # do a system-wide install
 $ hg debuginstall # sanity-check setup
 $ hg              # see help

Running without installing:

 $ make local      # build for inplace usage
 $ ./hg --version  # should show the latest version

See http://mercurial.selenic.com/ for detailed installation
instructions, platform-specific notes, and Mercurial user information.
