dirstate: remove the python-side whitelist of allowed matchers

This whitelist is too permissive because it allows matchers that contain
disallowed ones deep inside, for example through `intersectionmatcher`.

It is also too restrictive because it doesn't pass through
some of the matchers we support, such as `patternmatcher`.

It's also unnecessary because unsupported matchers raise
`FallbackError` and we fall back anyway.

Making this change makes more of the tests use rust code path,
and therefore subtly change behavior. For example, rust status
in largefiles repos seems to have strange behavior.

Testing recorded "modified" files for merge commit
==================================================

This file shows what hg says are "modified" files for a merge commit
(hg log -T {files}), somewhat exhaustively.

This test file shows merges that involves files contents changing

For merges taht involves executable bit changing, check test-merge-combination-exec-bytes.t

For testing of multiple corner case, check test-merge-combination-misc.t

Case with multiple or zero merge ancestors, copies/renames, and identical file contents
with different filelog revisions are not currently covered.

  $ . $TESTDIR/testlib/merge-combination-util.sh

All the merges of various file contents.

  $ range () {
  >   max=0
  >   for i in $@; do
  >     if [ $i = - ]; then continue; fi
  >     if [ $i -gt $max ]; then max=$i; fi
  >   done
  >   $TESTDIR/seq.py `expr $max + 1`
  > }
