* Makefile.am, configure.ac, sp39/init.c, sp39/sp39.scn: Move
unreliable third case in sp39 to spintrcritical10. New tests to hit
other event synchronization critical sections.
* spintrcritical11/.cvsignore, spintrcritical11/Makefile.am,
spintrcritical11/init.c, spintrcritical11/spintrcritical11.doc,
spintrcritical11/spintrcritical11.scn, spintrcritical12/.cvsignore,
spintrcritical12/Makefile.am, spintrcritical12/spintrcritical12.doc,
spintrcritical12/spintrcritical12.scn: New files.
* sp09/screen01.c, sp09/screen12.c, sp25/system.h, sp25/task1.c,
sp28/init.c, sp39/init.c, sp41/init.c, spfatal01/testcase.h,
spfatal08/testcase.h: Change size_t to ssize_t on all Heap, Workspace
and Region calls. On 16-bit architectures, size_t can be 16-bits
which would limit sizes to 64K. Also address constants which
overflowed on 16-bit integer targets.
* sp39/init.c: Add case for long timeout on blocking operation.
* Makefile.am, configure.ac: Add new test to exercise thread
queue blokcing synchronization. sp39 and sp41 are very similar.
* sp41/.cvsignore, sp41/Makefile.am, sp41/init.c, sp41/sp41.scn,
sp41/system.h: New files.
