Use the new control message to move ethernet addresses from a link to
a new link in ng_bridge(4). Send this message instead of doing the
work directly requires to move the loop detection into the control
message processing. This will delay the loop detection by a few
frames.
This decouples the read-only activity from the modification under a

Every usage of MB_CUR_MAX results in a call to __mb_cur_max. This is
inefficient and redundant. Caching the value of MB_CUR_MAX in a global
variable removes these calls and speeds up the runtime of sort. For
numeric sorting, runtime is almost halved in some tests.

Skyzall found an interesting panic in rack. When a SYN and FIN are
both sent together a KASSERT gets tripped where it is validating that
a mbuf pointer is in the sendmap. But a SYN and FIN often will not
have a mbuf pointer. So the fix is two fold a) make sure that the
SYN and FIN split the right way when cloning an RSM SYN on left
edge and FIN on right. And also make sure the KASSERT properly
accounts for the case that we have a SYN or FIN so we don't
panic.

Since 2.4.5 scapy started issuing warnings about a few different

stderr output, which upsets atf_check.
Configure scapy to only log critical errors (and thus not warnings) to

The various protocol implementations are not very consistent about
freeing mbufs in error paths. In general, all protocols must free both
"m" and "control" upon an error, except if PRUS_NOTREADY is specified
(this is only implemented by TCP and unix(4) and requires further work
not handled in this diff), in which case "control" still must be freed.
This diff plugs various leaks in the pru_send implementations.

Commit 81728a538 ("Split rtinit() into multiple functions.") removed
the initialization of sa6, but not one of its uses. This meant that we
were passing an uninitialized sockaddr as the address to
lltable_prefix_free(). Remove the variable outright to fix the problem.
The caller is expected to hold a reference on pr.
