testsuite traceaio.c

Add simple test program calling io_submit() with several iocbs, testing
handling or PWRITE, PREAD, PWRITEV, and PREADV.

The test can be run manually by compiling the program, running it with
"stap -c", and inspecting the generated trace.

With more work, this can be used in "make installcheck", and verified
using expected output file.
