mq: add parent node IDs to MQ patches on qrefresh/qnew

The goal of this patch is to add the IDs of the parents of applied MQ patches
into the patch file headers whenever qnew or qrefresh are run.

This will serve as a reminder of when the patches last applied cleanly and
will let us do more intelligent things in the future, such as:

    * Resolve conflicts found when qpushing to a new location by merging
      instead of simply showing rejects.

    * Display better diffs of versioned MQ patches because we can tell how the
      patched files have changed in the meantime.

Here are the new rules this patch introduces.  They are checked in this order:

    * If a patch currently has old, plain-style patch headers ("From:" and
      "Date:") do not change the style or add any new headers.

    * If the 'mq.plain' configuration setting is true, only plain-style
      headers will be used for all MQ patches.

    * qnew will initialize new patches with HG-style headers and fill in the
      "# Parent" header with the appropriate parent node.

    * qrefresh will refresh the "# Parent" header with the current parent of
      the current patch.

 '''manage a stack of patches
 
 This extension lets you work with a stack of patches in a Mercurial
 repository. It manages two stacks of patches - all known patches, and
 applied patches (subset of known patches).
 
 Known patches are represented as patch files in the .hg/patches
 directory. Applied patches are both patch files and changesets.
 
 Common tasks (use "hg help command" for more details)::
 
   prepare repository to work with patches   qinit
   create new patch                          qnew
   import existing patch                     qimport
 
   print patch series                        qseries
   print applied patches                     qapplied
 
   add known patch to applied stack          qpush
   remove patch from applied stack           qpop
   refresh contents of top applied patch     qrefresh
 
 By default, mq will automatically use git patches when required to
 avoid losing file mode changes, copy records, binary files or empty
 files creations or deletions. This behaviour can be configured with::
 
   [mq]
   git = auto/keep/yes/no
 
 If set to 'keep', mq will obey the [diff] section configuration while
 preserving existing git patches upon qrefresh. If set to 'yes' or
 'no', mq will override the [diff] section and always generate git or
 regular patches, possibly losing data in the second case.

     Use the qguard command to set or print guards on patch, then use
     qselect to tell mq which guards to use. A patch will be pushed if
     it has no guards or any positive guards match the currently
     selected guard, but will not be pushed if any negative guards
     match the current guard. For example::
 
         qguard foo.patch -stable    (negative guard)
         qguard bar.patch +stable    (positive guard)
         qselect stable
 
     This activates the "stable" guard. mq will skip foo.patch (because
     it has a negative match) but push bar.patch (because it has a
     positive match).
 
     With no arguments, prints the currently active guards.
     With one argument, sets the active guard.
 
     Use -n/--none to deactivate guards (no other arguments needed).
     When no guards are active, patches with positive guards are
     skipped and patches with negative guards are pushed.
 
     qselect can change the guards on applied patches. It does not pop
     guarded patches by default. Use --pop to pop back to the last
     applied patch that is not guarded. Use --reapply (which implies
     --pop) to push back to the current patch afterwards, but skip
     guarded patches.
 
     Use -s/--series to print a list of all guards in the series file
     (no other arguments needed). Use -v for more information.'''
