Commit 6251ccf032 ('python3: fix the
value of PYTHON3_PATH') tried to fix the value of PYTHON3_PATH, but
did it incorrectly: it changed PYTHON_VERSION_MAJOR to
PYTHON_VERSION3_MAJOR, while it should have been
PYTHON3_VERSION_MAJOR.

The PYTHON3_PATH was incorrectly referencing the site-packages of
Python 2 packages, due to the usage of PYTHON_VERSION_MAJOR, instead
of PYTHON3_VERSION_MAJOR. This commit fixes that by using the correct
variable, which in our testing fixed the build of python-pyasn against
python3.

This patch reworks the way python3 and python3-config symlink are
installed.
Buildroot wants to control these symlinks' installation:
* the python3 symlink should be unconditionally installed in the target
tree, and the python3-config symlink in the staging tree, since it is
the only python package built and installed in the target tree if the
user selected it;
* the python3 and python3-config symlinks should only be installed in
the host tree when python3 is the selection of the user for the
target.

During installation, host-python and host-python3 run the freshly built
python executable. This is done with a proper LD_LIBRARY_PATH to make
sure it picks up the libpython in the build directory. However, the
python binary has an RPATH pointing to the $(HOST_DIR)/usr/lib.
Therefore, if libpython exists there, it will be used instead.
If the install step is run in parallel, it is possible that libpython
is already partially copied to $(HOST_DIR)/usr/lib when python is run.
This gives an error like:
python: error while loading shared libraries: $(HOST_DIR)/usr/lib/libpython3.4m.so.1.0: file too short
The fix is simple: use RUNPATH instead of RPATH, which allows
LD_LIBRARY_PATH to override RUNPATH. That way, the libpython in the
build directory is always used. RUNPATH is enabled by passing
--enable-new-dtags to the linker.

A confusion was made when applying commit
c3d539b53f ('host python/python3:
conditionally disable unicodedata') and then commit
73293e88c8 ('python, python3: enable
unicodedata for host-python, needed by setuptools').
The first commit added the enabling of unicodedata in the host Python
when the target Python is configured with unicodedata, which is
necessary because building the target unicodedata Python module
requires having unicodedata support in the host Python.
The second commit enabled the unicodedata unconditionally in the host
Python, because it is needed by host-setuptools.
However, when the second commit was applied, the logic that consisted
in disabling unicodedate in the host Python when not needed was kept,
which resulted in breaking the build of host-setuptools due to the
lack of unicodedata support in the host python.
This commit fixes that by only leaving the unconditional
--enable-unicodedata in the host Python configuration options, and
therefore removing the problematic conditional --disable-unicodedata.

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.

The host python always had --disable-unicodedata, regardless of the
corresponding configuration option BR2_PACKAGE_PYTHON_UNICODEDATA.
Since the host python is used to byte-compile python modules, this meant
that such modules could not contain unicode strings. For example, following
statement in a python module:
print u"\N{SOLIDUS}"
would cause the byte-compilation to fail with message:
SyntaxError: ("(unicode error) \\N escapes not supported (can't load
unicodedata module)",
Instead, conditionally disable unicodedata based on
BR2_PACKAGE_PYTHON_UNICODEDATA, also for the host python.
This fixes bug #6542 (https://bugs.busybox.net/show_bug.cgi?id=6542)

The target python3 depends on host-python3, but most of the scripts
call "python", so we need to ensure that $(HOST_DIR)/usr/bin/python
exists. This patch achieves this by creating a python -> python3
symbolic link in $(HOST_DIR), just like we are already doing for the
target Python 3.

Some of the python2 patches were left behind when doing the python3
package. This was because the python build system can now autodetect
what packages can be built in the system.
However, some of these patches are actually useful to reduce drastically
the size of the interpreter.
This patch ports the relevant patches to the python3 package, and adds a
new patch to remove the idle3 IDE as well from the interpreter.
