[PATCH 0/7] Devtool/Recipetool: adding pypi support

[Julien Stephan <jstephan@baylibre.com>]

Hello all,

This series adds basic support for the pypi class in devtool/recipetool.

The idea is to be able to detect that a package is available on pypi and
in that case inherits from pypi class. This helps to produce cleaner
recipes for pypi packages.

To do this, I am adding a new optional callback "process_url" that
plugin can register to implement some logic on matching url.

By implementing this callback in create_buildsys_python we can match on
pypi URLs directly or on release tarballs hosted on "files.pythonhosted.org".

To create a recipe taking advantage of the pypi class we can use one of the
following new syntax:

* recipetool create https://pypi.org/project/<package>
* recipetool create https://pypi.org/project/<package>/<version>
* recipetool create https://pypi.org/project/<package> --version <version>

or the old syntax:

* recipetool create https://files.pythonhosted.org/packages/<...>

If the URL points to a github URL or a release tarball not coming from
"files.pythonhosted.org", the created recipe is the same as before.
One can also use the newly added "--no-pypi" switch to NOT inherit 
from pypi class on matching URL, to keep legacy behaviour.

This series also contains some bug fixes I found during my testing.

Pushed my dev branch here: https://git.yoctoproject.org/poky-contrib/log/?h=jstephan/devtool-add-pypi-support 

Cheers
Julien
