Name our filesystems mount function consistently.
Eliminate the namiedata argument to both vfs_mount and vfs_omount.
It was originally there to save stack space. A few places abused
it to get hold of some credentials to pass around. Effectively
it is unused.
Reorganize the root filesystem selection code.

- Eliminate the acquisition and release of Giant from vm_map_protect().
(Translation: mprotect(2) runs to completion without touching Giant on
alpha, amd64, i386 and ia64.)
brings ia64 to parity with alpha, amd64, and i386 in this area.)
- Prevent a race in pmap_find_pte(): If pmap_find_pte() sleeps in
uma_zalloc(), another thread could allocate a pte at the same address.
Instead, sleep at a higher level and retry the lookup before retrying
the allocation.

This is really ugly way to do this, but there is no other way for now.
It allows to mount root file system from providers which belong to

than one interface from the command line:
# /etc/rc.d/netif start bfe0 xl0
It's also possible to restart an interface(s):
# /etc/rc.d/netif restart bfe0
This required some changes to rc.subr(8) so that if the start/stop commands
are overidden the rest of the command line (after the start/stop/etc... cmd)
is passed through to the subroutines.

use a mutex because we want to be able to sleep while holding the

- Bump version number.
This allows for a quite interesting trick. One can setup a stripe with
stripe size of 512 bytes and create transparent provider on top of it
with sector size equal to <ndisks> * 512. The result will be something
like RAID3 without parity disk (every access will touch all disks).
