* Add initial package for vapoursynth
* Forgot to edit the PKGBUILD to include my name as contributor
* enable vapoursynth for mpv
* Enable vulkan support in SDL2
* SDL2: keep the -mwindows flag in the pkg-config --libs output
Removing this flag is an unexpected deviation from upstream which may
break building applications that rely on this flag being properly set
by SDL2, e.g.
https://github.com/chocolate-doom/chocolate-doom/issues/899
There may be applications out there using SDL2 which do not require
this flag, but they may still filter it out from the output of
'pkg-config --libs' themselves. We should not turn the exception into
the rule.
Fixes#2413
* SDL2: raise pkgrel to 2
* upgrade some broken packages
* correct some broken urls/checksums
* use secure urls where possible
* update PKGBUILD templates
* remove line-ending whitespace
* minor typos/fixes
Remaining md5sums either didn't download or
didn't pass checksum tests.
