This library allows several task to write to a message queue which can be
read by several other tasks. It is used by my shutdown command
(AmiNet:util/libs/shutdown.lzh).
Version 2 of this library uses semaphores instead of Forbid()/Permit() and
fixes several bugs which didn't appear in connection with the shutdown command.
Version 3 implements QAllocMsg() and QFreeMsg().
QMessage has a new field qm_Data which points to the payload (which is
write protected under AmigaOS versions/clones which support MEMF_SHARED_READ).
Version 3.1 can be compiled with gcc again.
