* simops (OP_10007E0): Update errno handling as most traps
...
do not invoke the host's functionality directly. Invoke
sim_io_stat() instead of stat() for implementing TARGET_SYS_stat.
Implement TARGET_SYS_fstat, TARGET_SYS_rename, and TARGET_SYS_unlink.

sim: punt zfree()
...
The sim keeps track of which allocations are zero-ed internally (via
zalloc) and then calls a helper "zfree" function rather than "free".
But this "zfree" function simply calls "free" itself. Since I can
see no point in this and it is simply useless overhead, punt it.
The only real change is in hw-alloc.c where we remove the zalloc_p
tracking, and sim-utils.c where zfree is delete. The rest of the
changes are a simple `sed` from "zfree" to "free".
