b6777878ff python3: Restructure python3 packaging and replace it with autopackaging
See previous commit (python2 version) for more info, since mostly
everything applies here as well.

Old manifest file had several issues:
 - Its unorganized and hard to read and understand it for an average
   human being.
 - When a new package needs to be added, the user actually has to modify
   the script that creates the manifest, then call the script to create
   a new manifest, and then submit a patch for both the script and the
   manifest, so its a little convoluted.
 - Git complains every single time a patch is submitted to the manifest,
   since it violates some of its guidelines.
 - It changes or may change with every release of python, its impossible
   to know if the required files for a certain package have changed
   (it could have more or less dependencies), the only way of doing so
   would be to install and test them all one by one on separate individual
   images, and even then we wouldnt know if they require less dependencies,
   we would just know if an extra dependency is required since it would
   complain, lets face it, this isnt feasible.
 - The same thing happens for new packages, if someone wants to add a new
   package, its dependencies need to be checked manually one by one.

Features/Fixes:
 - A new manifest format is used (JSON), easy to read and understand.
   This file is parsed by the python recipe and python packages
   read from here are passed directly to bitbake during parsing time.
 - It provides an automatic manifest creation task (explained on previous
   commit), which automagically checks for every package dependencies and
   adds them to the new manifest, hence we will have on each package
   exactly what that package needs to be run, providing finer granularity.
  - Dependencies are also checked automagically for new packages
   (explained on previous commit).

This patch has the same features as the python2 version but it differs
in the following ways:
 - Python3 handles precompiled bytecode files  (*.pyc) differently.
   for this reason and since we are cross compiling, wildcards couldnt be
   avoided on python3 (See PEP #3147 [1]).
   Both the manifest and the manifest creation script handle this
   differently, the manifest for python3 has an extra field for cached
   files, which is how it lets the user install the cached files or not
   via : INCLUDE_PYCS = "1" on their local.conf.
 - Shared libraries nomenclature also changed on python3, so again, we
   use wildcards to deal with this issue ( See PEP #3149 [2]):
 - Fixes python3 manifest, python3-core should be base and everything
   should depend on it, hence several packages were deleted:
   python3-enum, re, gdbm, subprocess, signal, readline.
 - When building python3-native it adds as symlink to it called
   nativepython3, which is then isued by the create_manifest task.
 - Fixes [YOCTO #11513] while were at it.

ae8d879006 python3: remove two setup.py cross-compile hacks
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.

3bce321c09 python3: remove obsolete db dependency
The bsddb module was removed in Python 3 and the dbm module doesn't support
Berkeley DB as an option, so this build dependency can be removed.

6fd0e23dbd python3: improve reproducibility
The compiled .pyc files contain time stamp corresponding to the compile time.
This prevents binary reproducibility. This patch allows to achieve binary
reproducibility by overriding the build time stamp by the value
exported via SOURCE_DATE_EPOCH.

Patch by Bernhard M. Wiedemann.

(see diff in setup.py)
It assigned libraries for multiprocessing module according
the host_platform, but not pass it to Extension.

In glibc, the following commit caused two definition of
sem_getvalue are different.
https://sourceware.org/git/?p=glibc.git;a=commit;h=042e1521c794a945edc43b5bfa7e69ad70420524
(see diff in nptl/sem_getvalue.c for detail)
`__new_sem_getvalue' is the latest sem_getvalue@@GLIBC_2.1
and `__old_sem_getvalue' is to compat the old version
sem_getvalue@GLIBC_2.0.

If not explicitly link to library pthread (-lpthread), it will
load glibc's sem_getvalue randomly at runtime.

Such as build python on linux x86_64 host and run the python
on linux x86_32 target. If not link library pthread, it caused
multiprocessing bounded semaphore could not work correctly.
...
>>> import multiprocessing
>>> pool_sema = multiprocessing.BoundedSemaphore(value=1)
>>> pool_sema.acquire()
True
>>> pool_sema.release()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: semaphore or lock released too many times
...

And the semaphore issue also caused multiprocessing.Queue().put() hung.

17d181f059 python3: fix weakref spewing exceptions during interp finalization
When py3 applications are exiting we often see errors similar to the
following:

Exception ignored in: <function WeakValueDictionary.__init__.<locals>.remove at 0x7fcb56b09400>
Traceback (most recent call last):
  File "/usr/lib64/python3.5/weakref.py", line 117, in remove
  TypeError: 'NoneType' object is not callable

After a quick search this was found to be a well reported issue
upstream and had an appropriate fix which is backported here.

0862df262d python3: Use _sysconfigdata.py to initialize distutils.sysconfig
Porting patch from
<409482251b>
to use _sysconfigdata.py to initialize distutils.sysconfig.

This patch makes that distutils.sysconfig doesn't need config-*/Makefile
in libdir any more. Next we can move it from python3-misc to python3-dev
package.
