[VDPAU] [PATCH 2/2] vdpau: do not export _vdp_DRI2* functions

[Emil Velikov]

Neither one is part of the public API, thus should never be used outside
of the library itself.

Add a PUBLIC and PRIVATE macros, that are used to annotate the function
visibility by setting the respective __attribute__((visibility("bla"))).
