Jeffery To fe78c07a31 python: Add pyproject.toml-based builds for host Python packages
Using pip to install host packages with pyproject.toml-based (PEP 517)
builds is problematic:

* If build isolation is used, pip will create an isolated build
  environment, install any build dependencies for the requested package,
  then build the requested package.

  It does not appear currently possible to have pip install the build
  dependencies with hash-checking mode enabled[1].

* If build isolation is not used, any build dependencies must be
  installed in the build environment before invoking pip to build the
  requested package[2].

  This would require creating a package dependency resolution system to
  install build dependencies, and any dependencies of dependencies, in
  the correct order.

* It is very difficult to patch the packages installed by pip.

This adds a new include file (python3-host-build.mk) with recipes to
install host Python packages with pyproject.toml-based builds. This is
backwards-compatible with packages that require running setup.py.

Besides addressing the above issues (the OpenWrt build system already
resolves dependencies between packages, checks all source downloads
against known hashes, and supports patching packages), host packages
also:

* Capture package licensing and maintainer information
* Enable uscan checking for package updates/CVEs
* Are a known concept for OpenWrt packagers/developers

The existing functionality of using host pip to install packages will
remain for now, but should be considered deprecated and expected to be
removed in the future.

This also updates Py3Build/CheckHostPipVersionMatch for the case where
the host-pip-requirements directory does not exist or is empty.

OpenWrt packages feed

Description

This is the OpenWrt "packages"-feed containing community-maintained build scripts, options and patches for applications, modules and libraries used within OpenWrt.

Installation of pre-built packages is handled directly by the opkg utility within your running OpenWrt system or by using the OpenWrt SDK on a build system.

Usage

This repository is intended to be layered on-top of an OpenWrt buildroot. If you do not have an OpenWrt buildroot installed, see the documentation at: OpenWrt Buildroot Installation on the OpenWrt support site.

This feed is enabled by default. To install all its package definitions, run:

./scripts/feeds update packages
./scripts/feeds install -a -p packages
