Multiple IPv6 addresses of the same prefix can be installed on the
same interface. The first address will install the prefix route into
the kernel routing table and that prefix will be marked as on-link.
Without RADIX_MPATH enabled, the other address aliases of the same
prefix will update the prefix reference count but no other routes
will be installed. Consequently the prefixes associated with these
addresses would not be marked as on-link. As such, incoming packets
destined to these address aliases will fail the ND6 on-link check
on input. This patch fixes the above problem by searching the kernel
routing table and try to find an on-link prefix on the given interface.

The proxy arp entries could not be added into the system over the
IFF_POINTOPOINT link types. The reason was due to the routing
entry returned from the kernel covering the remote end is of an
interface type that does not support ARP. This patch fixes this
problem by providing a hint to the kernel routing code, which
indicates the prefix route instead of the PPP host route should
be returned to the caller. Since a host route to the local end
point is also added into the routing table, and there could be
multiple such instantiations due to multiple PPP links can be
created with the same local end IP address, this patch also fixes
the loopback route installation failure problem observed prior to
this patch. The reference count of loopback route to local end would
be either incremented or decremented. The first instantiation would
create the entry and the last removal would delete the route entry.
r201543
-------
The IFA_RTSELF address flag marks a loopback route has been installed
for the interface address. This marker is necessary to properly support
PPP types of links where multiple links can have the same local end
IP address. The IFA_RTSELF flag bit maps to the RTF_HOST value, which
was combined into the route flag bits during prefix installation in
IPv6. This inclusion causing the prefix route to be unusable. This
patch fixes this bug by excluding the IFA_RTSELF flag during route
installation.

Change vlan interfaces to cope more usefully with the parent interface being
renamed. Previously the vlan interfaces would lose their configuration as if
the parent interface had been physically removed. Now vlan interfaces ignore
rename events.
- Add a new ifnet flag (IFF_RENAMING) that is set while an ifnet is being
renamed. This flag can be checked in ifnet departure/arrival event
handlers to treat rename events differently.
- Change the ifnet departure event handler in the if_vlan(4) driver to
ignore departure events due to a trunk interface being renamed.
- Rename the __tcpi_(snd|rcv)_mss fields of the tcp_info structure to remove
the leading underscores since they are now implemented.
- Implement the tcpi_rto and tcpi_last_data_recv fields in the tcp_info
structure.
As soon as geom_raid3 reports it's own stripe as sector size, report largest
underlying provider's stripe, multiplied by number of data disks in array,
due to transformation done, as array stripe.
Make sure the multicast forwarding cache entry's stall queue is properly
initialized before trying to insert an entry into it.

File flags handling fixes for ext2fs:
- Disallow setting of flags not supported by ext2fs.
- Map EXT2_APPEND_FL to SF_APPEND.
- Map EXT2_IMMUTABLE_FL to SF_IMMUTABLE.
- Map EXT2_NODUMP_FL to UF_NODUMP.
Note that ext2fs doesn't support user settable append and immutable flags.
EXT2_NODUMP_FL is an user settable flag also on Linux.

Print backspaces after echoing an EOF.
Applications like shells expect EOF to give no graphical output, while
our implementation prints ^D by default (tunable with stty echoctl).
Make the new implementation behave like the old TTY code. Print two
backspaces afterwards.
I totally forgot to MFC this, because the 8.0 freeze took a little
longer than I expected.

Unloading of the nfscl module is unsupported because newnfslock doesn't
support unloading. It's not trivial to implement newnfslock unloading so
for now just admit that unloading is unsupported and refuse to attempt
unload in all nfscl module event handlers.

Fix ordering of nfscl_modevent() and ncl_uninit(). nfscl_modevent() must
be called after ncl_uninit() when unloading the nfscl module because
ncl_uninit() uses ncl_iod_mutex which is destroyed in nfscl_modevent().
