This adds anaconda 2023.09 and miniconda 23.9.0.

The code for determining which Python version is bundled with which
version of Anaconda has not been updated in a while. I have added 3.10
and 3.11, both of which were used in bundles this year.

I also updated the URL for the source of this data, the Anaconda release
notes, because it has moved.

Headers have been moved to the 'tcl-tk' subdir
This was causing Tcl/Tk 8.5 from XCode SDK to be silently picked instead

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
https://github.com/python/cpython/issues/69906 for more information.

It seems that pyenv cannot install 2.7.18 on Mac M1 (Apple ARM).

openssl 1.0.2 does not have ARM support. M1 support was added in 1.1.1i according to
https://www.openssl.org/news/cl111.txt

All include directories should go into CPPFLAGS.
XCode SDK was being added to CFLAGS instead
which caused old Tcl/Tk in the SDK to override a newer one in Homebrew.

The old 3.1.1s URL returns a 404

The -s flag assures that nothing can be installed to user site-packages
but doesn't keep ensurepip from looking there for Pip.
If Pip is installed in the user site-packages directory, pip won't be installed
for the newly built python -- and its shim won't be created.
-I makes the build install Pip in any case.
The user site-packages installation will override it --
but we'll have the shim at least.

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 adds anaconda 2023.03, anaconda 2023.07, miniconda 23.3.1, and
miniconda 23.5.0.

Anaconda and miniconda have changed their version string format again,
so the parsing needs to be done differently. `add_miniconda.py` can now
parse all existing definition files properly.

This makes it easier to fix file names that cannot be parsed using the
current logic.

* Use OpenSSL 1.1.1u and remove patches for 1.1.1q

The bug is reported to manifest in Mandjaro Linux 6.3.5-2
