Remove need to link against libopenal

Browse source 
libopenal is loaded with dlopen() and for all used alBla and alcBla functions
there are function pointers (just like thee qgl stuff for OpenGL).
Thus there's no need to link against libopenal on compile-time.

There were a few occurences of "normal" openal functions (al* instead of qal*)
- they are fixed now.

This allows to use a yquake2 version compield with WITH_OPENAL=yes to be used
on systems that have no libopenal installed (the standard SDL sound backend
will be used then).
