ba2aeff9b2 Correct documentation of asynchronous/callback buffer I/O. 
Asynchronous is not the same as callback: asynchronous means there is
no completion notification, and can be used only with buffer-cached
buffers.

94dff34741 Add resize_root boot operation. If resize_root=YES in rc.conf then 
the system attempts to resize the root file system to fill it's
partition prior to mounting read-write. Useful for things like AMI
file system images. May eventually be used by arm images after
coming up with similar solution for increasing the parition size.

a37502b2b6 Add RTF_BROADCAST to mark routes used for the broadcast address when 
they are created on the fly. This makes it clear what the route is for
and allows an optimisation in ip_output() by avoiding a call to
in_broadcast() because most of the time we do talk to a host.
It also avoids a needless allocation for the storage of llinfo_arp and
thus vanishes from arp(8) - it showed as incomplete anyway so this
is a nice side effect.

Guard against this and routes marked with RTF_BLACKHOLE in
ip_fastforward().
While here, guard against routes marked with RTF_BLACKHOLE in
ip6_fastforward().
RTF_BROADCAST is IPv4 only, so don't bother checking that here.
