Set the IPOIB_FLAG_INITIALIZED on dev_open and clear it on dev_stop to
avoid a race between ipoib load and the underlying device driver.
The device module must dispatch the IB_EVENT_PORT_ACTIVE event before ipoib
module is loaded. Otherwise, the flush will fail since no one set the
IPOIB_FLAG_INITIALIZED.

* Check TLB1 in all mapdev cases, in case the memattr matches an existing
mapping (doesn't need to be MAP_DEFAULT).
* Fix mapping where the starting address is not a multiple of the widest size
base. For instance, it will now properly map 0xffffef000, size 0x11000 using
2 TLB entries, basing it at 0x****f000, instead of 0x***00000.

Ever since r143063, machine/atomic.h requires cdefs.h. So, include it
first. Weak support: style(9) tells us to include cdefs.h first.
Argument against: since code that includes systm.h still compiles,
compilation units that include systm.h must already include cdefs.h. So, an
argument could be made that the cdefs.h include could just be removed
entirely. That is maybe a bigger change and not one I am interested in
bikeshedding.
Universe compiles.

This introduces a facility to EVENTHANDLER(9) for explicitly defining a
reference to an event handler list. This is useful since previously all
invokers of events had to do a locked traversal of the global list of
event handler lists in order to find the appropriate event handler list.
By keeping a pointer to the appropriate list an invoker can avoid this
traversal completely. The pointer is initialized with SYSINIT(9) during
the eventhandler stage. Users registering interest in events do not need
to know if the event is backed by such a list, since the list is added
to the global list of lists. As with lists that are not pre-defined it
is safe to register for the events before the list has been created.
This converts the process_* and thread_* events to using the new
facility, as these are events whose locked traversals end up showing up
significantly in ports build workflows (and presumably other workflows
with many short lived threads/procs). It may be advantageous to convert
other events to using the new facility.
The el_flags field is now unused, but leave it be so that this revision
can be MFC'd.

Else the IPv6 address matching might fail. This change adds support for both
embedded and non-embedded IPv6 scope IDs when passing a IPv6 link-local socket
address to RDMA. Prior to this change only global IPv6 addresses would work
with RDMA.

1) Fail to resolve RDMA address if rtalloc1() returns the loopback
device, lo0, as the gateway interface. Currently RDMA loopback is
not supported.
2) Use ip_dev_find() and ip6_dev_find() to lookup network interfaces
with matching IPv4 and IPv6 addresses, respectivly.
3) In addr_resolve() make sure the "ifa" pointer is always set, also when
the "ifp" is NULL. Else a NULL pointer access might happen trying to
read from the "ifa" pointer later on.
4) In rdma_addr_find_dmac_by_grh() make sure the "bound_dev_if" field
gets set properly instead of passing the scope ID through the IPv6
socket address structure. This is more in line with upstream OFED
in Linux.
5) In rdma_addr_find_smac_by_sgid() there is no need to pass the
scope ID for IPv6. Either it is stored in the "bound_dev_if" field
or ip6_dev_find() will find the correct network device regardless
of the scope ID.

does not have to be interested for the user.
Changing logging level required to rebuild driver with proper flags. The
proper sysctl was added, so the level now can be changed dynamically
using bitmask.
Levels of printouts were adjusted to keep on mind end user instead of
debugging purposes.
More verbose messages were added to align the driver with the Linux.
