This is an API compatible reimplementation of Mattias Karlsson's and Andreas
Palsson's "ptreplay.library". Audio output is done as 16-bit, 44100 Hz, stereo
using "ahi.device". Module playback is done using an OS4 port of Ilkka
Lehtoranta's "ptplay.library".

The following functions of the library should be fully supported:
PTLoadModule, PTUnloadModule, PTPlay, PTStop, PTPause, PTResume, PTFade,
PTSetVolume, PTSongPos, PTSongLen, PTPatternPos, PTInstallBits, PTSetupMod,
PTFreeMod, PTStartFade, PTSetPos

Other functions are implemented simply as no-ops which do nothing except return
a constant value (usually null/zero) depending on the function definition.

Requirements:

 - AmigaOS 4.0 or newer
 - ptplay.library 2.6 (29.4.08)

Installation:

Copy ptreplay.library LIBS:
