Daniel Roethlisberger f076336e0b Don't allow -u on Mac OS X with pf proxyspecs
Apple checks EUID==0 on ioctl(/dev/pf), whereas OpenBSD and FreeBSD only
check permissions on open(/dev/pf).  This means that on OS X, it is not
possible to open /dev/pf, drop privileges, and send an ioctl to the file
descriptor opened earlier with EUID==0.  It also means Apple broke the
Unix way of dealing with device nodes - why are there file permissions
on /dev/pf when they later enforce EUID==0 on use, thereby breaking
basic Unix mechanisms?  Work around this by disallowing -u with pf
proxyspecs and by not automatically dropping to nobody on Mac OS X.

Daniel Roethlisberger c3922d9852 Refactor process lookup out of NAT engine code
Local process lookup is independent of the NAT engine used, it depends
only on the operating system's process enumeration API.  Moving the code
out of NAT lookup also makes it work for static and SNI proxyspecs.

Landon Fuller 9204418c80 Thread pid lookup support through the NAT API.
This exposes the pid lookup code as a standard attribute
of NAT lookup -- if a matching process cannot be found,
or if pid lookup isn't supported by the NAT backend,
a pid of -1 is returned.

This also adds the local_pid to the pxyconn context; this
will be used to populate log strings.
