[mythtv] /libs/libmyth/audiooutputbase.cpp

[Christian Hack]

/libs/libmyth/audiooutputbase.cpp seems to require these includes otherwise
current CVS won't compile for me.

#include <sys/types.h>       
#include <unistd.h>

Without them I get:

audiooutputbase.cpp: In member function `void 
   AudioOutputBase::OutputAudioLoop()':
audiooutputbase.cpp:477: `usleep' undeclared (first use this function)
audiooutputbase.cpp:477: (Each undeclared identifier is reported only once
for 
   each function it appears in.)
audiooutputbase.cpp: In static member function `static void* 
   AudioOutputBase::kickoffOutputAudioLoop(void*)':
audiooutputbase.cpp:550: `getpid' undeclared (first use this function)
