This is pretty self-explanatory, with most changes coming about as a
side-effect of argparse vs. optparse API differences.
Lowercase characters are used in help strings, per argparse conventions.
Some tests are converted because argparse natively supports unicode.

The 'sphinx-apidoc' tool is no longer the only kid on the block when it
comes to automatic documentation of Python projects, with the likes of
'sphinx-autoapi' in development [1], and is not really maintained. Given
the fact that the tool is tangential to Sphinx's main goal, there isn't
really anything that warrants its continue existence as a core module.
Signify this by moving the feature to 'ext'. This allows the feature to
continue to exist in the package, but indicates that stability might be
worse than one would expect from the core library.
To avoid breaking packages that are using this feature directly, such as
pbr [3], aliases for the old 'main' method are included. This is based
on what Django does and, like Django, will allow us to safely remove the
old modules in Sphinx 2.0.
