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] [3.6] bpo-33329: Fix multiprocessing regression on newer
- glibcs (GH-6575) (GH-6582)
-
-Starting with glibc 2.27.9000-xxx, sigaddset() can return EINVAL for some
-reserved signal numbers between 1 and NSIG.  The `range(1, NSIG)` idiom
-is commonly used to select all signals for blocking with `pthread_sigmask`.
-So we ignore the sigaddset() return value until we expose sigfillset()
-to provide a better idiom.
-(cherry picked from commit 25038ecfb665bef641abf8cb61afff7505b0e008)
