- Allow RTM_CHANGE to change a number of route flags as specified by
RTF_FMASK.
- The unused rtm_use field in struct rt_msghdr is redesignated as
rtm_fmask field to communicate route flag changes in RTM_CHANGE
messages from userland. The use count of a route was moved to
rtm_rmx a long time ago. For source code compatibility reasons
a define of rtm_use to rtm_fmask is provided.
These changes faciliate running of multiple cooperating routing
daemons at the same time without causing undesired interference.

protocol to the socket. Normally protocol references are weak: that is,
the socket layer can tear down the socket (and hence protocol state)
when it finds convenient. This flag will allow the protocol to
explicitly declare to the socket layer that it is maintaining a
strong reference, rather than the current implicit model associated
with so_pcb pointer values and repeated attempts to possibly free the
socket.

rather than panicking later. This can occur if the kernel calls
vn_open() on a fifo, as there will be no associated file descriptor,
and therefore the file descriptor operations cannot be modified to
point to the fifo operation set.

Previously, we tried to allow this only for root. However, we were calling
suser() on the *target* process rather than the current process. This
means that if you can ptrace() a process running as root you can set a
hardware watch point in the kernel. In practice I think you probably have
to be root in order to pass the p_candebug() checks in ptrace() to attach
to a process running as root anyway. Rather than fix the suser(), I just
axed the entire idea, as I can't think of any good reason _at all_ for
userland to set hardware watch points for KVM.
