Update limits and configuration parameters for 1003.1/TC1/D6.
Implement new sysconf keys. Change the implenentation of _SC_ASYNCHRONOUS_IO in preparation for the next set of changes. Move some limits which had been in <sys/syslimits.h> to <limits.h> where they belong. They had only ever been in syslimits.h to provide for the kernel implementation of the CTL_USER MIB branch, which went away with newsysctl years ago. (There is a #error in <sys/syslimits.h> which I will downgrade in the next commit.)
