setup: define build_doc command

Currently, various processes for packaging Mercurial state to
manually invoke `make -C doc` in order to generate the documentation.
This Makefile merely invokes `gendoc.py` and `runrst` to produce
man pages and HTML pages.

Not all environments may have the ability to easily run
Makefiles. Windows is notably in this set.

This commit ports the man page and HTML generation logic from
doc/Makefile to setup.py. We introduce a new build_doc command
which generates documentation by calling gendoc.py and runrst.
The documentation can now be built via pure Python by running
`python setup.py build_doc`.

We don't implement dependency tracking because IMO it is more
effort than it is worth.

We could potentially remove the duplicated functionality in
doc/Makefile. But I'm not sure what all is depending on it. So
I plan to keep it around.
