accrightslen is always used in an unsigned context so make it.

Remove unused macro definitions. OK'd by pgoyette.

Merge the [pgoyette-compat] branch

Remove compat_svr4 and compat_svr4_32, as discussed on tech-kern@ recently,
but also as discussed several times in the past.

Only compat_43 needs compat_osock. Note that the use of vec_compat_ifioctl
is racy.

include opt_compat_netbsd.h to get COMPAT_SOCKCRED70 defined.

Add sc_pid to sockcred so that SOCK_DGRAM and LOCAL_CREDS socket option
can learn the process id of the AF_LOCAL sender.
Add compat glue for old structure.

Use "defopt MODULAR" in sys/conf/files, and #include "opt_modular.h"
in all kernel sources that use the MODULAR option.
Proposed in tech-kern on 18 Jan 2009.

Provide compatibility to the old timeval SCM_TIMESTAMP messages.

Remove LKMs and switch to the module framework, pass 1.

Proposed on tech-kern@.

Clean up net compat ioctls, and clean up handling of wireless ioctls.

Changes to sompat socket function to avoid the dreaded stackgap.

Move the nasty ifdefs in one place. Requested by ad and dyoung.

Add a sockaddr_storage member to "struct ifreq" maintaining backwards
compatibility with the older ioctls. This avoids stack smashing and
abuse of "struct sockaddr" when ioctls placed "struct sockadd

Add a sockaddr_storage member to "struct ifreq" maintaining backwards
compatibility with the older ioctls. This avoids stack smashing and
abuse of "struct sockaddr" when ioctls placed "struct sockaddr_foo's" that
were longer than "struct sockaddr".
XXX: Some of the emulations might be broken; I tried to add code for
them but I did not test them.

Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
