Lock down a socket, milestone 1.

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()

Revised MLD-related definitions
- Used mld_xxx and MLD_xxx instead of mld6_xxx and MLD6_xxx according
to the official defintions in rfc2292bis
(macro definitions for backward compatibility were provided)
- Changed the first member of mld_hdr{} from mld_hdr to mld_icmp6_hdr
to avoid name space conflict in C++

This change makes ports/net/pchar compilable again under -CURRENT.

TODO:
- The definitions of SADB_* in sys/net/pfkeyv2.h are still different
from RFC2407/IANA assignment because of binary compatibility
issue. It should be fixed under 5-CURRENT.
- ip6po_m member of struct ip6_pktopts is no longer used. But, it
is still there because of binary compatibility issue. It should
be removed under 5-CURRENT.

Convert all users of fldoff() to offsetof(). fldoff() is bad
because it only takes a struct tag which makes it impossible to
use unions, typedefs etc.

Define __offsetof() in <machine/ansi.h>

Define offsetof() in terms of __offsetof() in <stddef.h> and <sys/types.h>

Remove myriad of local offsetof() definitions.

Remove includes of <stddef.h> in kernel code.

NB: Kernelcode should *never* include from /usr/include !

Make <sys/queue.h> include <machine/ansi.h> to avoid polluting the API.

Deprecate <struct.h> with a warning. The warning turns into an error on
01-12-2000 and the file gets removed entirely on 01-01-2001.
