bump version for libpcap (+tcpdump) import
Hand it to spaff, he knows how to say it:

Using encryption on the Internet is the equivalent of arranging
an armoured car to deliver credit card information from someone
living in a cardboard box to someone living on a park bench.

Add a new field, sy_auevent, to the system call entry description
structure, sysent.  This field will hold the default audit event
to generate when the system call is entered.  Currently, it will
default to 0 due to allocation in bss.

Normalize white space in syscalls.master: try to use tabs before system
call types.
Add missed ${.CURDIR}/../../contrib/bzip2 into include search path, otherwise
old version of bzlib.h can be picked up from the /usr/include.
White space normalization: use tabs instead of spaces before and after
the system call type field.
Catch up with s/dev_t/struct cdev */.
Eliminate aio_bufjobs; it's unused.
Make bzip2 support working again after bzip2 upgrade. This time commit
BZ_NO_COMPRESS support to the bzip2 sources directly (yes, this takes file
off the vendor branch, but looks like bzip2 maintainer doesn't care), so that
it will not be removed when the next upgrade is performed. Also, add a short
note on how to test bzip2 support.

Correct comment (libz -> libbz2) and remove useless full path to zutil.h
while I am here.
o  Call cninit_finish() in configure_final().
o  Remove unused and compiled-out code while here.
Call cninit_finish() and set cold to 0 in configure_final() instead
of in configure(). Call cninit_finish() before setting cold to 0.
This is how it's done for other platforms. Be alike to avoid problems.
Call cninit_finish() in configure_final().
Call cninit_finish() from configure_final().

Create nexus in configure_first() instead of in configure(). This
makes sure that sysinit tasks that run after configure_first(),
but before configure() have a nexus to hang devices off.
Correct mistake in previous commit: add 'bsm' to LDIRS not LSUBDIRS.

Pointy hat:	over here, please
malloc.h relies on param.h for a definition of MAXCPU.  I guess that there is
other header pollution that makes this work right now, but it falls over when
doing a RELENG_5 -> HEAD upgrade.
Eliminate aio_activeproc; it's unused.
