This replaces the getopt()/getopt_long() wrapper, the old-style
argument rewriter and the associated configuration glue with a more
straightforward custom command parser. In particular, this ensures
that bsdtar will have consistent option parsing on every platform,
regardless of whether the platform supports getopt_long().

-A Display the apparent size instead of the disk usage. This can be
helpful when operating on compressed volumes or sparse files.
-B blocksize
Calculate block counts in blocksize byte blocks. This is differ-
ent from the -k, -m options or setting BLOCKSIZE and gives an
estimate of how much space the examined file hierachy would
require on a filesystem with the given blocksize. Unless in -A
mode, blocksize is rounded up to the next multiple of 512.
The former is similar to GNU's du(1) --apparent-size. The latter is
different from what GNU's du(1) -B does, which is equivalent to setting
BLOCKSIZE in our implementation and is rather pointless as it doesn't add
any real value (i.e. you can achieve the same with a simple awk-script).
No change in the normal output or processing.

tcp_mss() and tcp_mss_update() so that tcp_mtudisc() could
re-use the same code.
Move the TSO logic back to tcp_mss() and out of tcp_mss_update().
We tried to avoid that initially but if were are called from
tcp_output() with EMSGSIZE, we cleared the TSO flag on the tcpcb
there, called into tcp_mtudisc() and tcp_mss_update() which
then would reenable TSO on the tcpcb based on TSO capabilities
of the interface as learnt in tcp_maxmtu/6().
So if TSO was enabled on the (possibly new) outgoing interface
it was turned back on, which lead to an endless loop between
tcp_output() and tcp_mtudisc() until we overflew the stack.

tcp_mss() and tcp_mss_update() so that tcp_mtudisc() could
re-use the same code.
In case we return early and got a metricptr to pass the hostcache
info back to the caller we need to initialize the data to a defined
state (zero it) as tcp_hc_get() would do if there was no hit.
Without that the caller would check on random stack garbage which
could lead to undefined results.
This only affected tcp_mss() if there was no routing entry for the peer,
tcp_mtudisc() was not affected.

NATM needs 'struct in_addr' to compile, which is a problem on its own
but include in.h for now if we have NATM but neither INET or INET6.

Add an ANCACHE check to poperly hide the case and make an(4)
