use a mutex lock when looking up/deleting entries on the hashlist
use a mutex lock on each uidinfo when updating fields
make uifree() a void function rather than 'int' since no one cares
allocate uidinfo structs with the M_ZERO flag and don't explicitly initialize
them

Rename malloc_options to have a leading underscore, I belive I have been
told that is more correct namespace wise.
call instead.
This makes a pretty dramatic difference to the amount of work that
the harvester needs to do - it is much friendlier on the system.
(80386 and 80486 class machines will notice little, as the new
get_cyclecounter() call is a wrapper round nanotime(9) for them).
`wait.h' that was in contrib/binutils/, however this wait.h went away with
bintuils 2.10.0 so I `cvs rm'ed it. Now we find gdb will not build. This
binutils wait.h contained nothing we didn't already have in <sys/wait.h>.
So just hack a symlink to it.
the interface to use callout_* instead of timeout(). Also add an
IS_MPSAFE #define (currently off) which will mark the driver as mpsafe
to the upper layers.
before adding/removing packets from the queue. Also, the if_obytes and
if_omcasts fields should only be manipulated under protection of the mutex.
IF_ENQUEUE, IF_PREPEND, and IF_DEQUEUE perform all necessary locking on
the queue. An IF_LOCK macro is provided, as well as the old (mutex-less)
versions of the macros in the form _IF_ENQUEUE, _IF_QFULL, for code which
needs them, but their use is discouraged.
Two new macros are introduced: IF_DRAIN() to drain a queue, and IF_HANDOFF,
which takes care of locking/enqueue, and also statistics updating/start
if necessary.
root's groups' permissions were being used, so a user could read up to
16 (excluding initial whitespace) bytes of e.g. a wheel-accessible file.
Also, don't allow blocking on the opening of ~/.fakeid, so replace a fopen()
with open() and fdopen(). I knew I'd be going to hell for using C file
streams instead of POSIX syscalls...
maxvnodes, numvnodes, freevnodes, nchstats, and numdirtybuffers.
o Make the hw.ncpu error checking code a little more rigorous by
sanity checking the returned data size.
o Didn't fix machine-dependent non-sysctl-exported variables:
intrnames, eintrnames, intrcnt, eintrcnt, as these variables are
defined and exported from machine-dependent kernel code in
assembly. This should probably be fixed somehow.
