Move MINSIGSTKSZ from <machine/signal.h> to <machine/_limits.h> and rename

Browse Source 
it to __MINSIGSTKSZ.  Define MINSIGSTKSZ in <sys/signal.h>.

This is done in order to use MINSIGSTKSZ for the macro PTHREAD_STACK_MIN
in <pthread.h> (soon <limits.h>) without having to include the whole
<sys/signal.h> header.
