James Hilliard 8937db8dd5 package/pkg-python.mk: migrate setuptools to pep517 
Now that setuptools and its dependencies are using pep517 we can
migrate the setuptools infrastructure itself to use the pep517
build frontend.

As part of this we need to migrate the all python packages using
_BUILD_OPTS to the new config settings format used by the pep517
build frontend.

We need to use a setup.cfg file to pass the pg_config path when
building python-psycopg2 as this package needs the pg_config
path for all internal build stages while -C--build-option= only
passes the flag to the internal bdist_wheel stage.

Use new setup type variables to define setup type specific
dependencies instead of using the conditional block.

In python-m2crypto, the --openssl option is a build_ext option
so we need to add -C--build-option build_ext in front of it.

We also need to set --skip-dependency-check for the following
packages which specify build dependencies that are not actually
required:
 - python-lxml
 - python-matplotlib
 - python-msgpack
 - python-pymupdf
 - python-uvloop
 - python-wsaccel

# Python package infrastructure
#
# This file implements an infrastructure that eases development of
# package .mk files for Python packages. It should be used for all
# packages that use Python setup.py/setuptools as their build system.
#
# See the Buildroot documentation for details on the usage of this
# infrastructure
#
# In terms of implementation, this Python infrastructure requires the
# .mk file to only specify metadata information about the package:
# name, version, download URL, etc.
#
# We still allow the package .mk file to override what the different
# steps are doing, if needed. For example, if <PKG>_BUILD_CMDS is
# already defined, it is used as the list of commands to perform to
# build the package, instead of the default Python behaviour. The
# package can also define some post operation hooks.
