The per file descriptor semaphore (field of rtems_libio_t) is unused in
RTEMS. There is a considerable memory overhead due to that. A
semaphore needs roughly 124 bytes which is huge compared to the
approximately 72 bytes for the file descriptor structure itself. Device
drivers can create their own synchronization primitives in the open
handler on demand.
* Makefile.am, configure.ac: Removed some fifo tests.
* spfifo01/Makefile.am, spfifo01/init.c: Minor changes to avoid
excessive new lines in the output.
spfifo02/Makefile.am, spfifo02/init.c, spfifo02/spfifo02.doc,
spfifo02/spfifo02.scn, spfifo03/Makefile.am: Merge from spfifo08.
Also added a few more cases, mostly from spfifo04/init.c.
* spfifo03/init.c, spfifo03/spfifo03.doc, spfifo03/spfifo03.scn:
Previously was spfifo06. Configure parameter for pipes is used now.
* spfifo04/.cvsignore, spfifo04/Makefile.am, spfifo04/init.c,
spfifo04/spfifo04.doc, spfifo04/spfifo04.scn, spfifo08/.cvsignore,
spfifo08/Makefile.am, spfifo08/init.c, spfifo08/spfifo08.doc,
spfifo08/spfifo08.scn: Removed.
