[arch-general] `multicat` package added to AUR

[Sébastien Leblanc]

Hi, I made a PKGBUILD for VideoLAN's multicat utility. It is a
content-agnostic (optimized for MPEG TS) uni/multicast streaming
software suite. It is often considered a multicast version of the
netcat utility. It is very lightweight: a compiled package weighs 41K
It is available on the AUR under the name `multicat`.

>From their website:
> Simple and efficient multicast and transport stream manipulation
> The multicat package contains a set of tools designed to easily and efficiently manipulate multicast streams in general, and MPEG-2 Transport Streams (ISO/IEC 13818-1) in particular.
> The multicat suite of applications is very lightweight and designed to operate in tight environments. Memory and CPU usages are kept to a minimum, and they feature only one thread of execution.
