o Add a mutex (sb_mtx) to struct sockbuf. This protects the data in a
socket buffer. The mutex in the receive buffer also protects the data
in struct socket.
o Determine the lock strategy for each members in struct socket.
o Lock down the following members:
- so_count
- so_options
- so_linger
- so_state
o Remove *_locked() socket APIs. Make the following socket APIs
touching the members above now require a locked socket:
- sodisconnect()
- soisconnected()
- soisconnecting()
- soisdisconnected()
- soisdisconnecting()
- sofree()
- soref()
- sorele()
- sorwakeup()
- sotryfree()
- sowakeup()
- sowwakeup()

fix a comment that suggested setting ipv6_ipv4mapping to blank. This
will aid in merging with rcng which requires all veriables to be
explicitly set.

make_dev() to create device nodes for each of the serial port channels
(ttym%d and cuam%d respectively, as borrowed from MAKEDEV). This allows
the rc driver to work in 5.0. I've tested it with only one card, but
will try sticking in a second card tomorrow and see what happens.

Change msU macros to mU.
This is only a partial solution; the whole issue of building the
documentation needs to be revisited.
combining too much conditions and as such ended up with the
kernel map instead of the corresponding process map. While
here, remove code to allow access to the stackgap and restyle
slightly to improve readability.
This fix specifically fixes the procfs failure we're having
when reading the process map (cat /proc/curproc/map)
As a minor positive side-effect, code at -O0 is more optimal. As a
minor negative side-effect, certain boundary cases yield no better
code than non-boundary cases. For example, atomic_set_acq_32(p, 0)
does a useless logical OR with value 0. This was previously elimina-
ted as part of if/while optimizations. Non-boundary cases yield
identical code at -O1 and -O2.

ptrace() for permission checking, but do it inline.

o While here, copy-in arguments before we lock. This fixes
a possible permanent lock.
