Subject: Remove current implementation of kldstat macro.

Add new kldstat, kldstat-v and kernel macros.  The kldstat macro is
functionally equivalent to the previous implementation, but it looks
prettier and it matches the kldstat-v macro better.  kldstat-v gives
output similar to userland kldstat -v (note lacking space), and kernel
loads a new kernel and dump.
