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.

- Don't discard SRCCONF value since it may incorrectly have MAKEOBJDIRPREFIX

- If OBJROOT is SRCTOP then don't add on TARGET.TARGET_ARCH. This
only happens at the top-level, and for sub-directories when the
user is clever with MAKEOBJDIRPREFIX=/.
- Don't bother checking 'test -w' on .CURDIR.
- Properly set OBJTOP/OBJROOT to SRCTOP in various needed cases.
- Check if the OBJDIR is writable even for *clean* targets since it
determines which .OBJDIR the user gets; If they cannot write to an
existing eligible .OBJDIR then it needs to clean in .CURDIR instead.
- Add guard to cleanworld/cleanuniverse from removing SRCTOP.
- Ensure OBJTOP is proper for .OBJDIR=.CURDIR which fixes finding
libraries since src.libnames.mk is based on OBJTOP.
- Avoid some chdir(2) for modifying .OBJDIR

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.

The directives I added in r323466 and r323501 did not define a valid
CFA until several instructions into the associated functions. This
triggers an assertion in GDB when generating a stack trace while
stopped at the first instruction of PLT stub entry point since there
is no valid CFA rule for the first instruction.
This is probably just wrong on my part as the non-simple .cfi_startproc
would have defined a valid CFA. Instead, define a valid CFA as sp + 0
at the start of the functions and then use .cfa_def_offset to change the
offset when sp is adjusted later in the function.

This is only cosmetic, but the entry point for rtld is not a leaf function,
and this avoids two .frame directives for rtld_start.

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.

This avoids the obvious of not running the target when expected, but
also avoids META_MODE from showing 'Building'. This is mostly only
a problem when directly including bsd.obj.mk as many of these targets
were already .PHONY via bsd.sys.mk.

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.

such, leading to some performance impact. As a test I ran the same IO
