This commit allows building Python with the following libraries
installed via MacPorts:
- ncurses
- openssl
- readline
- zlib (XCode SDK zlib is still tried first)
If either Homebrew or MacPorts system is the only one installed, that system
will be used automatically.
When both systems are installed, then whatever is found first in PATH - brew
or port - will be used for all dependencies.
The following environment variables can be set to non-empty value to override
the selection:
PYTHON_BUILD_USE_HOMEBREW
PYTHON_BUILD_USE_MACPORTS
Tcl/Tk specific support is omitted due to CPython incompatibility with
Tcl/Tk 9, according to the comments in use_homebrew_tcltk().
Those who need Tcl/Tk module, can use PYTHON_CONFIGURE_OPTS --with-tcltk-libs=
pointing to the Tcl/Tk location which can be installed either from sources or
via MacPorts.
Tests for added *_macports_* functions are based off of the corresponding
brew counterparts.

XCode Command Line Tools 15.0 was recently released, and it contains a
broken version of ncurses 6.0. Some uses of Python's `curses` module
will segfault when compiled with it. The solution is to switch to using
the version of ncurses from Homebrew, which is currently 6.4. Support
for ncurses 6 was added to Python 3.7 and was backported to 3.6 and 2.7,
so this change should not break any recently supported Python versions.
Tested with Python 3.12, 3.11, and 2.7, and all tests in
the `test.test_curses` module pass without issue.
See https://github.com/python/cpython/issues/109617 and

Guthub have recently preinstalled x64 Homebrew OpenSSL to stock MacOS runners. This has caused FreeBSD OpenSSL detection logic to erroneously trigger when running FreeBSD tests in MacOS because their paths happened to coincide.
Replaced checking a specific path with checking with pkg.
This is needed to find other Python deps (e.g. libintl) in Homebrew if it has
nonstandard prefix (e.g. in Apple M1)
* Re-allow to search Homebrew for zlib everywhere
Link to the active version like other Homebrew deps --
this won't break when another binary-compatible version is installed.
Use a discovery method that doesn't break when other versions are present alongside.
Because the variables specified via command-line arguments for the
`./configure` will be favored than one in environment variables,
setting those variables in `PACKAGE_CONFIGURE_OPTS_ARRAY` will hide
existing environment variables.
To avoid the problem, stop using `package_option()` to setup those
variables.
