though I would personally prefer to see the broken nameservers fixed
instead of standards compliant applications work around them, I can't
force FreeBSD users to help fight that battle.

changing indentation and some comments. Main goal is not perfect style,
but just to reduce differences with NetBSD. The object code is exactly
the same after this change as before it (except for assert() statements
which have moved).

- Don't explicitly enter and exit critical sections when walking lock
lists. We don't need a critical section to walk the list of sleep
locks for a thread. We check to see if a spin lock list is empty
before we walk it. If the list is empty we don't need to walk it. If
it isn't then we already hold at least one spin lock and are already in
a critical section and thus don't need our own explicit critical
section.

to handle this case properly, we must not use >= when comparing
queue sizes to qlimit. As a result of this improper handling,
a panic could result in certain cases.

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()
