* spu/sbrk.c: Use the current stack pointer value rather than the
maximum available memory to determine the amount of heap space
left. Without this change calling sbrk() can allocate space that
is currently in use on the stack.

JSRE_WRITEV opcodes.

* spu/pwrite.c: New file to add pwrite via assist call.
* spu/readv.c: New file to add readv via assist call.
* spu/writev.c: New file to add writev via assist call.
* spu/jsre.h: Add JSRE_SCHED_YIELD, JSRE_UMASK, JSRE_UTIME, and
JSRE_UTIMES.
* spu/sched_yield.c: New file add sched_yield via assist call.
* spu/umask.c: New file add umask via assist call.

* spu/shm_unlink.c: New file to add shm_unlink via assist call.
* spu/Makefile.in: Add shm_open.o and shm_unlink.o
* spu/dirfuncs.c: New file, holds the opendir, closedir, readdir,
rewinddir, seekdir and telldir implementations. These are
grouped in one file so that we do not need a separate file for
the struct dirent and DIR allocation code.
* spu/jsre.h: Add JSRE_OPENDIR and other dir opcodes.
* spu/Makefile.in: Add dirfuncs.o.
