Update the following dists:
bzip2, xz, libiconv, gettext, ninja, meson, libgcrypt, libsecret, sdl2,
flac, libogg, libvorbis, wxwidgets
and the following ffmpeg deps:
graphite2, xvidcore, libgsm, opus, libsoxr, libass, libbluray, libvpx,
libx264, libx265
Enable ffmpeg for vbam again as we now have working recording code
thanks to @denisfa.
Disable graphviz and libzvbi for the time being since we don't really
need them.
For mp3lame use the msys2 patch to remove posix code instead of linking
to catgets.
For libogg and libvorbis on mac, add `-include /path/to/stdint.h` to
`CFLAGS` when building.
