tests: introduce c-style conditional sections in .t tests

This makes it possible to have conditional sections like:

#if windows
  $ echo foo
  foo
#else
  $ echo bar
  bar
#endif

The directives and skipped sections are treated like comments, so don't
interleave them with commands and their output.

The parameters to #if are evaluated while preparing the test by passing them
over to hghave. Requirements can thus be negated with 'no-' prefix, and
multiple requirements must all be true to return true.

  $ hg init

  $ python -c 'file("a", "wb").write("confuse str.splitlines\nembedded\rnewline\n")'
  $ hg ci -Ama -d '1 0'

  $ echo clean diff >> a
