The sim-basics.h is too big and includes too many things. This leads
to some arch's sim-main.h having circular loop issues with defs, and
makes it hard to separate out common objects from arch-specific defs.
By splitting up sim-basics.h and killing off sim-main.h, it'll make
it easier to separate out the two.
The execv prototypes on Windows via mingw64 include extra const
markings on the argv/envp pointers than what POSIX specifies.
Cast them to void* as a hack to get it working on all platforms.
The defs.h header will take care of including the various config.h
headers. For now, it's just config.h, but we'll add more when we
integrate gnulib in.
This header should be used instead of config.h, and should be the
first include in every .c file. We won't rely on the old behavior
where we expected files to include the port's sim-main.h which then
includes the common sim-basics.h which then includes config.h. We
have a ton of code that includes things before sim-main.h, and it
sometimes needs to be that way. Creating a dedicated header avoids
the ordering mess and implicit inclusion that shows up otherwise.
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).
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.
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.

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.
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".
