match: replace match class by match function (API)

The matcher class is getting hard to understand. It will be easier to
follow if we can break it up into simpler matchers that we then
compose. I'm hoping to have one matcher that accepts regular
(non-include) patterns, one for exact file matches, one that always
matches (and maybe one that never does) and then compose them by
intersection and difference.

This patch takes a simple but important step towards that goal by
making match.match() a function (and renaming the matcher class itself
from "match" to "matcher"). The new function will eventually be
responsible for creating the simple matchers and composing them.

icasefsmatcher similarly gets a factory function (called
"icasefsmatch"). I also moved the other factory functions nearby.

====================================
Testing head checking code: Case C-2
====================================

Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.

This case is part of a series of tests checking this behavior.

Category C: checking case were the branch is only partially obsoleted.
TestCase 1: 2 changeset branch, only the head is rewritten

.. old-state:
..
.. * 2 changeset branch
..
.. new-state:
..
.. * 1 new changesets branches superceeding only the head of the old one
.. * base of the old branch is still alive
..
.. expected-result:
..
.. * push denied

Actual testing
--------------

  $ hg push
  pushing to $TESTTMP/C1/server (glob)
  searching for changes
  abort: push creates new remote head 25c56d33e4c4!
  (merge or see 'hg help push' for details about pushing new heads)
