extdiff: add --per-file and --confirm options

The new options lets the user control how the external program is run.
By default, Mercurial passes the 2 snapshot directories as usual, but
it can also run the program repeatedly on each file's snapshot pair,
and optionally prompt the user each time.

      Show differences between revisions for the specified files, using an
      external program. The default program used is diff, with default options
      "-Npru".
  
      To select a different program, use the -p/--program option. The program
      will be passed the names of two directories to compare. To pass additional
      options to the program, use -o/--option. These will be passed before the
      names of the directories to compare.
  
      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.
  
  (use 'hg help -e extdiff' to show help for the extdiff extension)
  
  options ([+] can be repeated):
  
   -p --program CMD         comparison program to run
   -o --option OPT [+]      pass option to comparison program
   -r --rev REV [+]         revision
   -c --change REV          change made by revision
      --patch               compare patches for two revisions
   -I --include PATTERN [+] include names matching the given patterns
   -X --exclude PATTERN [+] exclude names matching the given patterns
   -S --subrepos            recurse into subrepositories

      external program. The default program used is diff, with default options
      "-Npru".
  
      To select a different program, use the -p/--program option. The program
      will be passed the names of two directories to compare, unless the --per-
      file option is specified (see below). To pass additional options to the
      program, use -o/--option. These will be passed before the names of the
      directories or files to compare.
  
      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.
  
      The --per-file option runs the external program repeatedly on each file to
      diff, instead of once on two directories.
  
      The --confirm option will prompt the user before each invocation of the
      external program. It is ignored if --per-file isn't specified.
