python3: revert puting the encodings folder into a python3-codecs
Some notes about the 'encodings' module, which is about 1.7 MB.
Unfortunately that one cannot be moved into the 'python3-codecs'
package, because Python tries to load up all available encodings
at startup.
Some efforts to add a dummy folder/python file have failed so far,
since there's a C code (Python/codecs.c) that tries to evaluate that
all encodings (in the encodings folder/module) are valid.
Basically the encodings module is a repository of encodings,
and it seemst there are quite a few of them.
Maybe a request to upstream Python would work for this, to
make encodings a bit more decoupled from the interpreter.

python3: enable shared python3 lib; make this the norm
This will reduce the bloat when users will want to compile in their
Python C extensions.
There will be a initial bloat (several kb) if just Python
is installed, but that will be compensated when users will add more
C extensions.
During the build we also have to add Python's PKG_BUILD_DIR
so that the shared lib is found when compiling Python's
built-in C extensions.

Some notes:
- Python 3 (at least version 3.4) is pretty cross-compiler-friendly,
so a lot of patches were thrown away.
- Arguments below were moved to ./files/config.site file, and disabled
ac_cv_have_chflags=no \
ac_cv_have_lchflags=no \
ac_cv_py_format_size_t=no \
ac_cv_have_long_long_format=yes \
ac_cv_buggy_getaddrinfo=no \
- --without-ensurepip added, because the build wants to ensure that
it works; that's a good idea, but for now, it requires special
setup, and we can do that later
- --without-pymalloc added, becase in Python 3, modules are suffixed
with m; e.g. so some paths are python3.4m instead of python3.4
all this is detailed here:
http://legacy.python.org/dev/peps/pep-3149/
Maybe it will be a good idea to re-add this back

Make python-mini the top-level and default Python package.
Make the other packages subpackages of the top-level python package.
Make old python package the python-full package.
Note: at this point, this package can be split/renamed to
python-legacy should anyone need Python 2. After this commit
it's going to be Python 3 all the way.
