mq: add an '-e/--exact' option to qpush

This patch adds an '--exact/-e' option to qpush that will try to push the
patches in the correct location in the DAG.  Specifying this option does the
following:

* If --move is specified, abort. It makes no sense to move a patch to the front
  of the queue and try to apply it to its parent, because its parent is one of
  the patches we just moved it in front of!
* If patches are already applied, abort. We don't want patch changesets
  scattered throughout the DAG.
* If local changes are present, abort unless --force is used, as usual.
* Find the first patch we're going to push (if we're pushing multiple patches
  with a target or --all).
* If that patch doesn't have a parent, abort, obviously.
* If the parent doesn't exist in the repo, abort.  Something is wrong.
* Update to the parent, then continue pushing the patches as normal.

  use 'echo' to diff repository (or selected files)
  
      Show differences between revisions for the specified files, using the
      'echo' program.
  
      When two revision arguments are given, then changes are shown between
      those revisions. If only one revision is specified then that revision is
      compared to the working directory, and, when no revisions are specified,
      the working directory files are compared to its parent.
  
  options:
  
   -o --option OPT [+]       pass option to comparison program
   -r --rev REV [+]          revision
   -c --change REV           change made by revision
   -I --include PATTERN [+]  include names matching the given patterns
   -X --exclude PATTERN [+]  exclude names matching the given patterns
  
  [+] marked option can be specified multiple times
  
  use "hg -v help falabala" to show global options

  $ hg ci -d '0 0' -mtest1

  $ echo b >> a
  $ hg ci -d '1 0' -mtest2

Should diff cloned files directly:

  $ hg falabala -r 0:1
  diffing a.8a5febb7f867/a a.34eed99112ab/a
  [1]

Test diff during merge:

  $ hg update -C 0
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo c >> c
  $ hg add c
  $ hg ci -m "new branch" -d '1 0'
  created new head
  $ hg merge 1
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)

Should diff cloned file against wc file:

  $ hg falabala
  diffing a.2a13a4d2da36/a $TESTTMP/a/a
  [1]


Test --change option:

  $ hg ci -d '2 0' -mtest3
  $ hg falabala -c 1
  diffing a.8a5febb7f867/a a.34eed99112ab/a
  [1]

Check diff are made from the first parent:

  $ hg falabala -c 3 || echo "diff-like tools yield a non-zero exit code"
  diffing a.2a13a4d2da36/a a.46c0e4daeb72/a
  diff-like tools yield a non-zero exit code

Test extdiff of multiple files in tmp dir:

  $ hg update -C 0 > /dev/null
  $ echo changed > a
  $ echo changed > b
  $ chmod +x b

  $ hg diff --git
  diff --git a/a b/a

Edit with extdiff -p:

Prepare custom diff/edit tool:

  $ cat > 'diff tool.py' << EOT
  > #!/usr/bin/env python
  > import time
  > time.sleep(1) # avoid unchanged-timestamp problems
  > file('a/a', 'ab').write('edited\n')
  > file('a/b', 'ab').write('edited\n')
  > EOT

  $ chmod +x 'diff tool.py'

will change to /tmp/extdiff.TMP and populate directories a.TMP and a
and start tool

  $ hg extdiff -p "`pwd`/diff tool.py"
