qreslib implements a fairly thin compatibility layer for part of a
Linux API of AQuoSA, so I don't think the rtems/ subdirectory is the
right place (not an RTEMS API). How does a libcompat subdirectory of
cpukit sound? I propose we add a libcompat which can include a
subdirectory itself for arbitrary API compatibility layers. For this
work it would be cpukit/libcompat/qres/ and probably just have the
qreslib.h file.
