setup: build extensions in parallel by default

The build_ext distutils command in Python 3.5+ has a "parallel"
option that controls whether to build extensions in parallel. It
is disabled by default (None) and can be set to an integer value
for number of cores or True to indicate use all available CPU
cores.

This commit changes our build_ext command override to set
"parallel" to True unless a value has been provided by the caller.

On my machine, this makes `python setup.py build_ext` 1-4s faster.
It is worth noting that at this time, each individual source file
constituting the extension is still built serially. For Mercurial,
this means that we can't build faster than the slowest-to-build
extension, which is the zstd extension by a long shot. This means
that setup.py is still not very efficient at utilizing multiple
cores. But we're better than before.

  update the current patch
  
      If any file patterns are provided, the refreshed patch will contain only
      the modifications that match those patterns; the remaining modifications
      will remain in the working directory.
  
      If -s/--short is specified, files currently included in the patch will be
      refreshed just like matched files and remain in the patch.
  
      If -e/--edit is specified, Mercurial will start your configured editor for
      you to enter a message. In case qrefresh fails, you will find a backup of
      your message in ".hg/last-message.txt".
  
      hg add/remove/copy/rename work as usual, though you might want to use git-
      style patches (-g/--git or [diff] git=1) to track copies and renames. See
      the diffs help topic for more information on the git diff format.
