I-sync in pmap_remove_mapping() if the old mapping had PG_EXEC, and
kick curcpu (IMB) or other CPUs (via an IPI) only if the pmap was
the kernel pmap or active on other CPUs (curcpu is handled in userret()).
- Use lazy I-sync everywhere, (hopefully) eliminating the last of the
I-sync issues for multiprocessor support.
- Eliminate some memory barriers added in a couple of previous revisions,
after some discussion on port-alpha/tech-smp.
Still some lazy I-sync optimization possibilites:
- pmap_changebit() does not need to I-sync when only write-protecting
a page.
- pmap_asn_alloc() may be able to cancel a pending lazy I-sync when a
new ASN is allocated. Need to double check against Green Book or
Brown Book.

* Fixup the indenting in a few places to conform to NetBSD style
(/mnt)/usr/share/zoneinfo in a listbox, and setting (/mnt)/etc/localtime
accordingly.
* Adjust for the needed menuc change un run.c's log_flip() and script_flip()
functions.

* when selecting a item in a menu, call the opt_action() callback with
a pointer to the struct menudesc, so the callback has a chance to find
out which item was selected. Having a seperate callback for each
item is ok for small menus, but not for ones with many objects.
* Add menu-option MC_NOSHORTCUT to not print letters ("a: ", ...)
in front of list items. Again, this is for menues with lots of entries
as e.g. the upcoming sysinst set_timezone() function composes.

searchs (amongst others) are case insensitive.
* in interactive mode (-i), when editing entries display supported disk types

this feature is supported for the question).
* support `m' as a suffix equivalent to `M'

* deprecate deffstypename() and getfstypename()
