Add VLC media player, usable as an iOS command line audio player

[asdfugil]

This PR adds VLC media player, since I am not aware of a command line iOS audio player that can play many files formats. On macOS, an working GUI .app is made

What works on iOS:

• Audio playback
• cursus TUI vlc -I ncurses
• CLI prompt UI vlc -I oldrc
• CLI, no UI cvlc

On macOS, it would install VLC.app and does work correctly

The following projects are added as build dependencies for VLC

• libaacs
• libdvdread
• libdvdnav
• libbdplus
• libbluray
• libmpeg2
• libnfs
• libsmb2

While making this PR, problems are discovered and fixed in the following packages:

• sdl2
• aom
• mpg123
• libcaca

nasm does not accept CFLAGS-like flags, so set ASFLAGS to empty when assembling x86. misc: Verify libsodium download with a GPG key

Would it be possible to add VLC-iOS to this PR?

just download it from the App Store..., I don't see a point here

[asdfugil]

VLC-iOS is essentially, a wrapper of a wrapper around VLC for iOS and tvOS. Given that it is specifically made for iOS, it is must be somehow possible but I cannot see a reason to do that when it would be much better to download it from the App Store.

[m1stadev]

Fair enough.
