message Protect per-file counters and document which lock is used to protect
the other fields.

Once we no longer have any [k] (kernel lock) protections, we'll be
able to unlock almost all network related syscalls.

message When looping over mount points, the FOREACH SAVE macro is not save.
The loop variable mp is protected by vfs_busy() so that it cannot
be unmounted. But the next mount point nmp could be unmounted while
VFS_SYNC() sleeps. As the loop in vfs_stall() does not destroy the
mount point, TAILQ_FOREACH_REVERSE without _SAVE is the correct
macro to use.

message Introduce rtm_sendup() a function to deliver routing messages to a
socket receive buffer.

It is modelled after pfkey_sendup() as both will need the same MP

message Use fd_getfile() in sysctl_file() instead of rewriting it.

This gives use refcounting for free which is what we need for MP.

message Socket splicing can delay operations by task or timeout. Introduce
soreaper() that is scheduled onto the timer thread. soput() is
scheduled from there onto the sosplice task thread. After that it
is save to pool_put() the socket and splicing data structures.
