Attached vm ddb commands show map', show vmochk', `show object',
`show vmopag', `show page' and `show pageq'. Moved all vm ddb stuff to the ends of the vm source files. Changed printf() to db_printf(), `indent' to db_indent, and iprintf() to db_iprintf() in ddb commands. Moved db_indent and db_iprintf() from vm to ddb. vm_page.c: Don't use __pure. Staticized. db_output.c: Reduced page width from 80 to 79 to inhibit double spacing for long lines (there are still some problems if words are printed across column 79).
