ctime() may be marked obsolescent in the POSIX guide, but it is still

   POSIX.1-2008 marks asctime(), asctime_r(), ctime(), and ctime_r() as
   obsolete, recommending the use of strftime(3) instead.

I guess POSIX and ISO C should get together and talk then. I had this one on my todo list for a few years now, after noticing in the man page:

Moreover, ISO C says: "It is equivalent to

 asctime(localtime(timer))"

So, if you want to replace ctime(), why no using just that?

asctime() is obsolete too.

I don't insist on this commit if we're confident it won't be removed. However the latest POSIX still has them marked as such. Since it's an easy (and critical to Mutt) function, it seemed prudent to just roll our own.
