More work toward increasing NGROUPS_MAX and/or allowing kern.ngroups to
be increased at boot time.

 * Replace the embedded cr_groups[NGROUPS] member of struct cred with
   a pointer to malloc'd storage and a cr_agroups value which tracks
   the number of allocated group slots.  When more space is required
   crextend() is used to add more space.  The new crcopysafe() function
   calls crextend as needed when saving a copy of a credential from a
   process before modification.

 * Introduce a new #define, XU_NGROUPS which is always 16 and is used to
   set the array size in struct xucred and will be used other places
   where the 16 group limit needs to be preserved.

 * Replace the embedded ki_groups[KI_NGROUPS] entry in struct kinfo_proc
   with a pointer and adapt libkvm accordingly.
