5f05936d9b sim: v850: cleanup build warnings 
This port only had one minor warning left in it, so fix it and then
enable -Werror behavior by deleting the macro call.  We'll use the
common default now (which is -Werror).

44b30b7f0e sim: v850: fix handling of SYS_times 
My recent rewrite of the nltvals generator fixed a bug where SYS_times
was not being exported for v850.  But that in turn uncovered this bug
where the SYS_times codepath had a compile error.

68ed285428 sim: clean up C11 header includes 
Since we require C11 now, we can assume many headers exist, and
clean up all of the conditional includes.  It's not like any of
this code actually accounted for the headers not existing, just
whether we could include them.

The strings.h cleanup is a little nuanced: it isn't in C11, but
every use of it in the codebase will include strings.h only if
string.h doesn't exist.  Since we now assume the C11 string.h
exists, we'll never include strings.h, so we can delete it.

d0f0baa272 * 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.

d79fe0d643 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".
