ddb: add new command `show slabinfo'

* ddb/db_command.c (db_show_cmds): Add `slabinfo'.
* kern/slab.c (slab_info): Generalize so that it can be used with
different printf-like functions, and turn it into a static function.
(slab_info): New wrapper retaining the old behaviour.
(db_show_slab_info): New wrapper that uses `db_printf' instead.
* kern/slab.h (db_show_slab_info): New declaration.
