commands: use dirstateguard instead of begin/end-parentchange for backout

Before this patch, "hg backout" uses 'begin'/'end'-'parentchange()'
of 'dirstate' class to avoid writing incomplete dirstate changes out
at failure.

But this framework doesn't work as expected, if 'dirstate.write()' is
invoked between them. In fact, in-memory dirstate changes may be
written out at 'repo.status()' implied by 'merge.update()', even
before this patch.

To restore dirstate as expected at failure of "hg backout", this patch
uses 'dirstateguard' instead of 'begin'/'end'-'parentchange()'.

Test that the syntax of "unified tests" is properly processed
==============================================================

Simple commands:

  $ echo foo
  foo
  $ printf 'oh no'
  oh no (no-eol)
  $ printf 'bar\nbaz\n' | cat
  bar
  baz

Multi-line command:

  $ foo() {
  >     echo bar
  > }
  $ foo
  bar

Return codes before inline python:

  $ sh -c 'exit 1'
  [1]

Doctest commands:

  >>> print 'foo'
  foo
  $ echo interleaved
  interleaved
  >>> for c in 'xyz':
  ...     print c
  x
  y
  z
  >>> print
  
  >>> foo = 'global name'
  >>> def func():
  ...     print foo, 'should be visible in func()'
  >>> func()
  global name should be visible in func()
  >>> print '''multiline
  ... string'''
  multiline
  string

Regular expressions:

  $ echo foobarbaz
  foobar.* (re)
  $ echo barbazquux
  .*quux.* (re)

Globs:

  $ printf '* \\foobarbaz {10}\n'
  \* \\fo?bar* {10} (glob)

Literal match ending in " (re)":

  $ echo 'foo (re)'
  foo (re)

Windows: \r\n is handled like \n and can be escaped:

#if windows
  $ printf 'crlf\r\ncr\r\tcrlf\r\ncrlf\r\n'
  crlf
  cr\r (no-eol) (esc)
  \tcrlf (esc)
  crlf\r (esc)
#endif

Combining esc with other markups - and handling lines ending with \r instead of \n:

  $ printf 'foo/bar\r'
  fo?/bar\r (no-eol) (glob) (esc)
#if windows
  $ printf 'foo\\bar\r'
  foo/bar\r (no-eol) (glob) (esc)
#endif
  $ printf 'foo/bar\rfoo/bar\r'
  foo.bar\r \(no-eol\) (re) (esc)
  foo.bar\r \(no-eol\) (re)

testing hghave

  $ hghave true
  $ hghave false
  skipped: missing feature: nail clipper

  $ hghave no-true
  skipped: system supports yak shaving

#if no-true
  $ echo skipped

  $ echo tested
  tested
