2) Killed i386pagesperpage as it is not used by anything.
3) Fixed benign miscalculations in pmap_bootstrap().
4) Moved allocation of ISA DMA memory to machdep.c.
5) Removed bogus vm_map_find()'s in pmap_init() - the entire range was
already allocated kmem_init().
6) Added some comments.
virual_avail is still miscalculated NKPT*NBPG too large, but in order to

Change -F hw (hardware flow control) option to -h as in slattach,
we don't need option with argument for only one case.
Call downscript on SIGTERM.
Improve debug diagnostic.
Allow startslip work with several slip lines without killing each other.
Unlink pid file on exit.
Skip \r and \0 in login script parsing instead making them \n.
