Subject: [PATCH] Add <limits.h> header

According to the UNIX standard, <pthread.h> does not include some
PTHREAD_* values which are included in <limits.h>. OpenZFS uses
some of these values in its code, and this might cause build failure on
systems that do not have these PTHREAD_* values in <pthread.h>
