Make better use of GNU Pth -- patch by Andy Dustman.
I can't test this, so I'm just checking it in with blind faith in Andy.
I've tested that it doesn't broeak a non-Pth build on Linux.

Changes include:

- There's a --with-pth configure option.

- Instead of _GNU_PTH, we test for HAVE_PTH.

- Better signal handling.

- (The config.h.in file is regenerated in a slightly different order.)

    handler ignores signals if getpid() isn't the same as in the main
    thread.  XXX This is a hack.
 
+   GNU pth is a user-space threading library, and as such, all threads
+   run within the same process. In this case, if the currently running
+   thread is not the main_thread, send the signal to the main_thread.
