Remove two unneeded hacks. The first hack ("setup.py: no host headers
libs" patch) is not needed because we use cross-compiler (e.g.
i586-oe-linux-gcc) which has not been configured with any host system
include or library directories, and thus, we don't get any host system
directories when running "gcc -E -v".
The second hack becomes useless after the first hack has been removed
and we get the standard include and lib directories normally from gcc.

Useful in developing Python, e.g. in benchmarking.

Without this the pgo-related compiler flags are not used in
cross-builds.

This patch makes it possible to build python3 with profile directed
optimization. That is, feed python build process with profile data to
guide optimization. This is the third (and the last) step in profile
directed optimization for Python 3.x.
In order to do a profile-optimized build you need to specify
PYTHON3_PROFILE_OPT = "1" in your local.conf, and, have profile data available
in the location pointed to by PYTHON3_PROFILE_DIR. Profile data can be
obtainen e.g. by running bitbake python-pgo-image -c profile3.

This patch adds a new recipe that builds a special version of python3 that
produces profile data used for optimization. The new recipe directly includes
the base python recipe so that they are build in as similar way as possible and
this hopefully decreases the recipe maintenance burden, too. Also, its files
clash with the "normal" python3 so they cannot be installed in an image at the
same time.
Normally, profile-guided-optimization in Python is done simply by doing "make
profile-opt" which first builds python with profile instrumentation enabled,
then runs a profile task to get the profile data, and last, re-builds python
with profile data guiding the optimization. However, in our cross-build
environment this gets a lot trickier. We need to split out the steps as
building is done on the build host but we need to run the second step (i.e. run
the profile task) on the target hardware. This patch enables the first step,
i.e. building python with profile instrumentation enabled

Many new users add "python3" to their image using IMAGE_INSTALL and are then
surprised that they can't import any of the standard library. This is because we
split up the standard library into a number of packages, and python3-core (the
interpreter and essential modules only) RPROVIDES 'python3'.
Solve this by moving the RPROVIDES of 'python3' to python3-modules, so that the
entire Python standard library is installed.

python3 fails to work with recent glibc versions on older hosts, giving
errors like:
Fatal Python error: getentropy() failed
Aborted
This breaks buildtools-tarball and hence eSDK. This patch backports the
changes to random.c from upstream that address the problem.

Remove the patch that was applied in the python3 and python3-native
recipes to skip compilation of python modules.
Modify generate-manifest-3.5.py to match '__pycache__' directories in
FILES_*.
This is necessary because Python3 puts .pyc files in '__pycache__'
subdirectories one level below the corresponding .py files, whereas in
Python2 they used to be right next to the sources.
This change significantly reduces the startup overhead of Python3
scripts. For example, on a Cortex-A9, "python3 -c pass" took 0.40s
before, and 0.19s after.

Adding argparse module from Python's standard library. This allow use
argparse without installing all python-misc modules. For compatibility,
add python3-argparse as RDEPENDS to python3-misc.
