Fixes #23047.
ENV.x11: always add include/freetype2 to CPPFLAGS
ENV.x11: only use SDK when CLT is missing and X11 is from Apple
superenv: fix hardcoded X11 aclocal path
Check types in Formula#==

Comparing two objects should not raise an exception, even if they have
different types.

The semantics of #== are now the same as #eql?, so make one an alias.

Redact GNU Arch

This project has been removed from GNU mirrors.

Debian still packages a version of it, so users of this software
could switch the formula to use the Debian download, though we
no longer want to carry this in core.
lcrack: use debian
jenkins: add TLS mail support to plist.
jenkins 1.533
scm-manager 1.34

libav: 9.9 - tools to encode/decode video

Partially adapted from the ffmpeg formula. libav compilation seems robust, I
tested on two laptops and installed alongside ffmpeg without issue. I also
tested with all build options enabled.

Previous mention of a libav formula was at #12534.

Closes #20827.
