Fold "malloc" into "stdio" and -- recognizing that no program so far has
used less than "stdio" -- include all the "self" operations. Instead of
different defines, use regular PLEDGE_* in the "p_pledgenote" variable
(which indicates the operation subtype a system call is performing). Many
checks before easier to understand. p_pledgenote can often be passed
directly to ktrace, so that kdump says:
15565 test CALL pledge(0xa9a3f804c51,0)
15565 test STRU pledge request="stdio"
15565 test RET pledge 0
15565 test CALL open(0xa9a3f804c57,0x2<O_RDWR>)
15565 test NAMI "/tmp/testfile"
15565 test PLDG open, "wpath", errno 1 Operation not permitted
