Subject: Fixed namespace pollution in uma changes: - use `struct uma_zone *'
 instead of uma_zone_t, so that <sys/uma.h> isn't   a prerequisite. - don't
 include <sys/uma.h>. Namespace pollution makes "opaque" types like uma_zone_t
 perfectly non-opaque.  Such types should never be used (see style(9)).

"Fixed" subsequently grown dependencies of this header on its own
pollution by polluting explicitly:
- include <sys/mutex.h> and its prerequisite <sys/lock.h> instead of
  depending on namespace pollution 2 layers deep in <sys/uma.h>.
