Thomas Petazzoni 0d327c267a python3: bump to 3.4.0rc1
This commit bumps the Python3 package to use Python 3.4.0rc1.

About the patches:

 * The patches below 100 are significantly changed, because like for
   Python 2.x, a good number of improvements have been made in the
   upstream Python for cross-compilation. Therefore, almost all of
   these patches have been modified.

 * All the patches above 100 are simply updated for Python 3.4.0, with
   a small refactoring for the handling of test modules.

The details of the python3.mk changes are:

 * --without-ensurepip to tell Python to not use PIP at build time.

 * Many environment variables are no longer passed, they were specific
   to our cross-compilation patches

 * The fixup of the LIBDIR in the Python Makefile is no longer needed
   since Python has switched to _sysconfigdata.py for distutils
   configuration instead of parsing the Makefile.

 * A new post patch hooks touches the two files generated by pgen to
   make sure they are newer than the pgen sources, which ensures pgen
   is not built/executed.

Add infrastructure to disable the build of certain extensions
Some of the extensions part of the Python core have dependencies on
external libraries (sqlite, tk, etc.) or are relatively big and not
necessarly always useful (CJK codecs for example). By extensions, we
mean part of Python modules that are written in C and therefore
compiled to binary code.
Therefore, we introduce a small infrastructure that allows to disable
some of those extensions. This can be done inside the configure.ac by
adding values to the DISABLED_EXTENSIONS variable (which is a
word-separated list of extensions).
The implementation works as follow :
* configure.ac defines a DISABLED_EXTENSIONS variable, which is
substituted (so that when Makefile.pre is generated from
Makefile.pre.in, the value of the variable is substituted). For
now, this DISABLED_EXTENSIONS variable is empty, later patches will
use it.
* Makefile.pre.in passes the DISABLED_EXTENSIONS value down to the
variables passed in the environment when calling the setup.py
script that actually builds and installs those extensions.
* setup.py is modified so that the existing "disabled_module_list" is
filled with those pre-disabled extensions listed in
DISABLED_EXTENSIONS.
Patch ported to python2.7 by Maxime Ripard <ripard@archos.com>, and
then extended by Thomas Petazzoni
<thomas.petazzoni@free-electrons.com>.
