Before POSIX standardized strsignal(), old systems would hide the
prototype unless the normal extension defines were enabled. So use
the AC_USE_SYSTEM_EXTENSIONS helper for that.
Then make sure we include string.h ourselves in nrun.c rather than
relying on implicit includes via other sim headers.

Lift the code that GDB is using to generate dependencies on the fly and
port it over to the sim. Now people shouldn't have to manually maintain
these in their Makefile's.

Automake likes to dump macros automatically used into the aclocal.m4
file, but the common/aclocal.m4 naming prevents that. So rename it
to the more normal "acinclude.m4" so the aclocal tool can work.

Now that the sourceware tree generally requires autoconf-2.64, update
the sim tree to require that too.
This allows us to drop the long standing SIM_AC_COMMON/common.m4
workaround as autoconf 2.64+ seems to work for me.

Since sim_do_command for many people simply calls sim_args_command, start
a unified version of it. For people who handle their own options, they
could switch to this by using sim_add_option_table instead.

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".

As pointed out by Sandra Loosemore, a bunch of targets define sim_write
themselves instead of using the common/ code. So constify them too.
