Due to the use of printf("foobar "), iptables emits spaces at the
end-of-line, which looks odd to some users because it causes the
terminal to wrap even if there is seemingly nothing to print.
It may also have other points of annoyance, such as mailers
interpreting a trailing space as an indicator that the paragraph
continues when format=flowed is also on.
And git highlights trailing spaces in red, so let's avoid :)
Preexisting inconsistencies in outputting spaces in the right
spot are also addressed right away.

Match and target parse functions now only get option characters they
have defined themselves.

"u_int" was a non-standardized extension predating C99 on some platforms.

When using a bundled option like "-ptcp", 'argv[optind-1]' would
logically point to "-ptcp", but this is obviously not right.
'optarg' is needed instead, which if properly offset to "tcp".
Not all places change optind-based access to optarg; where
look-ahead is needed, such as for tcp's --tcp-flags option for
example, optind is ok.

In going to fix NF bug #611, "argv" is needed in
xtables_check_inverse to set "optarg" to the right spot in case of an
intrapositional negation.

This constant would be the designated one for the .family field; it
also, given recent changes, makes grep for NFPROTO_UNSPEC work to
finally recollect all manpages.

This also adds a warning that intrapositional negation support
is deprecated.

A number of comments are redundant, some outdated and others outright
wrong in their own way. Remove and fixup.

Give symbols of libxt matches unique names (1/3).
Adds unique prefixes to all functions (most of them - especially the hook
functions) so that debugging programs can unambiguously map a symbol to an
address. Also unifies the names of the xtables_match/xtables_target structs,
(based upon libxt_connmark.c/libip6t_*.c).

I've kept .print=NULL and .save=NULL so it stands out
(since iptables will do the print/save then).
