Add "make mode" to sphinx-build, invoked by the -M flag.

This is intended to do almost all of what the quickstart-generated Makefile
and make.bat did, but within Sphinx.  The advantages are:

* no duplication between Unix and Windows files
* updates and fixes are propagated (the generated makefiles never update)
* more Python code, less shell code!
