python: convert to autotargets, bump to 2.7.1, many improvements

This commit does a number of changes and improvements to the Python
interpreter package :

 * It converts the .mk file to the AUTOTARGETS infrastructure. Even
   though Python uses only autoconf and not automake, the AUTOTARGETS
   is a fairly good fit for the Python interpreter, so we make use of
   it.

 * It bumps the version to 2.7.1. As this is a minor release compared
   to 2.7, there are no particular changes needed because of this
   bump. All changes done to the package are cleanups and improvements
   unrelated to the version bump.

 * It uses the system libffi. Until now, Python was building its own
   libffi (a library used by interprets to build code that makes
   function call at runtime). Using the Python internal libffi was not
   working as Python was not passing the appropriate arguments down to
   libffi ./configure script. And it sounded better to use a
   system-wide libffi, that could potentially be used by other
   packages as well. This libffi is needed for the ctypes Python
   module.

 * Remove all "depends on BR2_PACKAGE_PYTHON" by moving all
   Python-related options under a "if BR2_PACKAGE_PYTHON ... endif"
   condition.

 * Make the installation of pre-compiled Python modules (.pyc) the
   default, since they are smaller and do not need to be compiled on
   the target. It is still possible to install uncompiled modules, or
   both the uncompiled and pre-compiled versions.

 * The options to select the set of Python modules to compile has been
   moved to a submenu.

 * The codecscjk (Japanese, Korean and Chinese codecs) module is no
   longer enabled by default.

 * The commented options for gdbm and nis in Python have been
   removed. Those were not supported, so let's get rid of unused code.

 * The option for the tkinker module in Python has been removed, since
   we don't have a package for Tk in Buildroot.

 * Options for the bzip2, sqlite and zlib modules have been added,
   since those modules have external dependencies.

 * The set of patches has been completely reworked and extended, with
   more fine-grained patches and newer functionalities. The patches
   are split in two categories:

    - Patches that make various modifications to the Python build
      system to support cross-compilation or make some minor
      modifications. Those patches are numbered from 0 to 100.

    - Patches that add configuration options to the Python build
      system in order to enable/disable the compilation of Python
      extensions or modules (test modules, pydoc, lib2to3, sqlite, tk,
      curses, expat, codecs-cjk, nis, unicodedata, database modules,
      ssl, bzip2, zlib). These patches are numbered from 100 to 200.

   All features of the previous four patches are preserved, but they
   are organized differently and the patches have been renamed. This
   makes it difficult to see the differences from the existing
   patches.

 * The host Python interpreter is now installed in $(HOST_DIR), since
   it is used to build third party Python modules.

 * The BR2_PACKAGE_PYTHON_DEV option is removed since
   BR2_HAVE_DEVFILES already does the necessary work.

 * The "make -i install" workaround introduced by Maxime Ripard is no
   longer needed. It was caused by the compilation of the tests that
   required the unicodedata module (which wasn't built in the host
   Python interpreter). Since we no longer compile the Python tests,
   the problem doesn't exist anymore and we can avoid this "-i"
   option.

+Add support in Python build system to specify host tools
+
+Python needs a Python interpreter and a "pgen" program to build
+itself. Unfortunately, the Python build system assumes that it can use
+the interpreter and pgen program it has just built to build
+itself. Obviously, this cannot work in cross-compilation mode since
+the interpreter and the pgen program have been built for the target.
+
+Therefore, this patch adds support in the Python build system for the
+new PYTHON_FOR_BUILD and PGEN_FOR_BUILD variables, so that we can
+point Python ./configure script to the Python interpreter and pgen
+program that have been previously built for the host.
+
+Patch ported to python2.7 by Maxime Ripard <ripard@archos.com>, and
+later significantly reworked by Thomas Petazzoni
+<thomas.petazzoni@free-electrons.com>, with some inspiration taken
+from the Python patches of the PTXdist project.

+Pass a CROSS_COMPILING variable to setup.py
+
+The setup.py script in the Python source code plays a significant role
+in the Python build process. It is responsible for building all the
+modules and extensions, and due to this, does various checks that need
+to be adjusted when we are cross-compiling.
+
+For that reason, this patch makes sure that a CROSS_COMPILING variable
+is passed in the environment of the setup.py script. Later patches in
+the stack make use of this variable.

+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.in by
+adding values to the DISABLED_EXTENSIONS variable (which is a
+word-separated list of extensions).
+
+The implementation works as follow :
+
+ * configure.in 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.

+Make sure setup.py reads the correct CONFIG_ARGS
+
+The setup.py script that builds and installs all the Python modules
+shipped with the interpreter looks at the CONFIG_ARGS variable stored
+in the "sysconfig" module to look at the ./configure options and
+adjust its behaviour accordingly.
+
+Unfortunately, when cross-compiling, the value of CONFIG_ARGS returned
+by the sysconfig are the one passed to the ./configure script of the
+*host* Python and not the one we're currently building for the target.
+
+In order to avoid that, we re-initialize the values in the sysconfig
+module by re-reading the environment at the beginning of the setup.py
+script, and we make sure that the CONFIG_ARGS variable is actually
+part of the environment of setup.py.
+
+See the beginning of
+http://article.gmane.org/gmane.comp.python.devel/99772 for the
+inspiration.

+Change the location of pyconfig.h
+
+The Python interpreter has a really strange behaviour: at *runtime*,
+it reads a Makefile and a header file named pyconfig.h to get some
+information about the configuration.
+
+The Makefile is located in usr/lib/python2.7/config, which is fine
+since this location is kept on the target.
+
+However, by default, the pyconfig.h is installed in
+usr/include/python2.7, but we completely remove the usr/include
+directory for the target. Since making an exception just for
+pyconfig.h is annoying, this patch also installs pyconfig.h to
+usr/lib/python2.7/config, and modifies the sysconfig module so that it
+looks in this location instead of usr/include.
+
+The pyconfig.h is still kept in usr/include/python2.7, because it is
+needed in the $(STAGING_DIR) when building third-party Python
+extensions that contain C code.

+Remove runtime library paths
+
+For some extensions (bsddb, sqlite and dbm), Python setup.py script
+hardcode a runtime path (rpath) into the extension. However, this
+runtime path is incorrect (because it points to the location of the
+library directory on the development machine) and useless (because on
+the target, all useful libraries are in a standard directory searched
+by the dynamic loader). For those reasons, we just get rid of the
+runtime paths in cross-compilation mode.

+Use correct mechanism to determine 32/64 bits
+
+Python setup.py builds certain extensions (dl and imageop) only on 32
+bits architecture. However, to test whether the architecture is 32
+bits or not, it was looking at the sys.maxint value of the host Python
+interpreter... which might run on a 64 bits architecture even though
+the target is 32 bits, or which might run on a 32 bits architecture
+even though the target is 64 bits.
+
+Therefore, we introduce a is_arch_64_bits() function, which looks at
+the pyconfig.h file generated by ./configure for the value of
+SIZEOF_LONG to determine if the architecture is 32 or 64 bits.

-The compileall script is used to compile to python bytecode all the modules.
-However, it relies on the struct package that is not built for the host
-python, thus crashing at execution when compiling the target python.
-When compiling, the removed code block is never executed, so we can safely
-remove it, removing in the same time the dependency on struct.
