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. # no-check-commit because forced foo_bar function names Differential Revision: https://phab.mercurial-scm.org/D6063

inno: remove references to pywin32 According to the commit message for 0c35bb01a1195, pywin32 was removed in Mercurial 1.8! Differential Revision: https://phab.mercurial-scm.org/D6062

inno: remove cacerts.pem from documentation The inno distribution no longer includes cacert.pem as of ca1ad8ef38be22 (April 2015). The docs were never updated. Differential Revision: https://phab.mercurial-scm.org/D6061

inno: replace add_path.exe with a Pascal script While attempting to build the Inno installer, I was unable to find a copy of add_path.exe from the source site previously listed in the docs. Some quick Googling revealed that achieving this functionality in native Pascal scripts seems to be preferred these days. This commit vendors "Modify Path" (fetched from https://www.legroom.net/software/modpath) and plugs it into our Inno config file per its instructions. The existing Inno installer appears to only modify PATH for the current user (as opposed to at the system level). I've maintained this behavior with Modify Path. Although it would be trivial to change or add checkboxes to control the behavior. I'll leave this as a follow-up. Differential Revision: https://phab.mercurial-scm.org/D6060

inno: move inno installer files to contrib/packaging/inno Let's isolate the inno installer files to their own directory so the separation between things is clearer. This required adjusting a few relative paths and references to the old directory. Differential Revision: https://phab.mercurial-scm.org/D6059
