Pending patches & other changes

[Rich Felker <dalias@libc.org>]

Here is a list of patches I'm aware of that have been sent to the list
that I haven't yet applied or rejected:

[PATCH] generate debug_frame info for __syscall_cp_asm (i386) so gdb can get backtrace
[PATCH] fmtmsg: verify that label is in the correct format.
[PATCH] replace 'hlt' by 'ud2' in i386/x32/x86_64 a_crash implementations
[PATCH] conforming strverscmp() implementation

There are also a few patches from nsz on the radar:

http://port70.net/~nsz/musl/0001-add-IPTOS_CLASS_-macros-to-netinet-ip.h.patch
http://port70.net/~nsz/musl/0001-complex-fix-ctanh-0-i-nan-and-ctanh-0-i-inf.patch
http://port70.net/~nsz/musl/0001-inet_pton-clean-up.patch

and the BRE extensions that are still under discussion, and possibly
some cleanup of some always-false null checks in the failure path of
regcomp.

There's also the idea of changing getlogin[_r] to probe the actual
controlling terminal and its owner to get the "logged in user" rather
than just using $LOGNAME. I've done some work on this but it's not
done and not clean for commit.

Anything else I'm missing? Most of this probably won't go in the
release but I at least want to make sure we have a good inventory of
what's still pending.
