In rtinit1, use the interface fib instead of the process fib. The
latter wasn't very useful because ifconfig(8) is usually invoked
with the default process fib. Changing ifconfig(8) to use setfib(2)
would be redundant, because it already sets the interface fib.

restricted to a single FIB in a multifib system.
Restricting an interface's routes to the FIB to which it is assigned (by
setting net.add_addr_allfibs=0) causes ARP updates to fail with "arpresolve:
can't allocate llinfo for x.x.x.x". This is due to the ARP update code hard
coding it's lookup for existing routing entries to FIB 0.

Replace fibs:udp_dontroute with fibs:src_addr_selection_by_subnet.
The original test was poorly written; it was actually testing
kern/167947 instead of the desired kern/187553. The root cause of the
bug is that ifa_ifwithnet did not have a fib argument. The new test
more directly targets that behavior.

Change {atf,plain,tap}.test.mk to be internal implementation details of
bsd.test.mk. Makefiles that build tests should now only include bsd.test.mk
and declaratively specify what they want to build, without worrying about
the internal implementation of the mk files.
The reason for this change is to permit building test programs of different
interfaces from a single directory, which is something I had a need for
while porting tests over from src/tools/regression/.
Additionally, this change makes it possible to perform some other requested
changes to bsd.test.mk in an easier manner. Coming soon.
mechanism, based on the new SB_STOP sockbuf flag. The old hack dynamically
changed the sending sockbuf's high water mark whenever adding or removing
data from the receiving sockbuf. It worked for stream sockets, but it never
worked for SOCK_SEQPACKET sockets because of their atomic nature. If the
sockbuf was partially full, it might return EMSGSIZE instead of blocking.
The new solution is based on DragonFlyBSD's fix from commit
3a6117bbe0ed6a87605c1e43e12a1438d8844380 on 2008-05-27. It adds an SB_STOP
flag to sockbufs. Whenever uipc_send surpasses the socket's size limit, it
sets SB_STOP on the sending sockbuf. sbspace() will then return 0 for that
sockbuf, causing sosend_generic and friends to block. uipc_rcvd will
likewise clear SB_STOP. There are two fringe benefits: uipc_{send,rcvd} no
longer need to call chgsbsize() on every send and receive because they don't
change the sockbuf's high water mark. Also, uipc_sense no longer needs to
acquire the UIPC linkage lock, because it's simpler to compute the
st_blksizes.
There is one drawback: since sbspace() will only ever return 0 or the
maximum, sosend_generic will allow the sockbuf to exceed its nominal maximum
size by at most one packet of size less than the max. I don't think that's
a serious problem. In fact, I'm not even positive that FreeBSD guarantees a
socket will always stay within its nominal size limit.

Add sbappendaddr_nospacecheck_locked(), which is just like

We shouldn't simply make sbappendaddr_locked check the space and
then call sbappendaddr_nospacecheck_locked, because that would cause
the O(n) function m_length to be called twice.

Now that 185813 is fixed, pipe_128k_8k fails intermittently due to

Move the installation of /usr/tests/lib/Kyuafile from src/tests/lib/
to src/lib/. This is to keep the src/tests/ hierarchy unaware of the
rest of the tree, which makes things clearer in general. In particular:
1) Everything related to the construction of /usr/tests/lib/ is kept
in src/lib/. There is no need to think about different directories
and how they relate to each other. (The same applies for libexec,
usr.bin, etc. but these are not yet handled.)
2) src/tests becomes the place to keep cross-functional test programs
and nothing else, which also helps in simplifying things.

- Add a top-level Kyuafile for /usr/tests and a way to create similar
