python3: upgrade to 3.7.2

I took the same approach as the recent perl upgrade: write recipe from scratch,
taking the pieces from the old recipe only when they were proven to be necessary.

The pgo, manifest and ptest features are all preserved.

New features:

- native and target recipes are now unified into one recipe

- check_build_completeness.py runs right after do_compile() and verifies that
all optional modules have been built (a notorious source of regressions)

- a new approach to sysconfig.py and distutils/sysconfig.py returning values
appropriate for native or target builds: we copy the configuration file to a
separate folder, add that folder to sys.path (through environment variable
that differs between native and target builds), and point python to the file
through another environment variable.

There were a few other patches where it was difficult to decide if the patch
is still relevant, and how to test that it works correctly; please add those
as-needed by testing the new python.

-Subject: [PATCH] bpo-29708: support SOURCE_DATE_EPOCH env var in py_compile
-
-to allow for reproducible builds of python packages
-
-See https://reproducible-builds.org/ for why this is good
-and https://reproducible-builds.org/specs/source-date-epoch/
-for the definition of this variable.
-
-Background:
-In some distributions like openSUSE, binary rpms contain precompiled .pyc files.
-
-And packages like amqp or twisted dynamically generate .py files at build time
-so those have the current time and that timestamp gets embedded
-into the .pyc file header.
-When we then adapt file timestamps in rpms to be constant,
-the timestamp in the .pyc header will no more match
-the .py timestamp in the filesystem.
-The software will still work, but it will not use the .pyc file as it should.
