Currently, libxt_statistic only dumps the probability with a
granularity of 1/1000000. Assuming only stuffed packets with 1440
bytes payload, this would match approximately every 1.341 GB, which is
pretty low for a high-volume router. Trying to match any larger
interval than that (e.g. 2 GB) will cause libxt_statistic to output
"--probability 0.000000", and when restored, will cause it to never
match again.
Bump the dump precision to what xt_statistic can really do, and adjust
the manpage to include a word about it.
Furthermore, employ explicit rounding when reading the argument from
the command line, because the previous implicit conversion would use
truncation, which is not very exact.

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.

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.

A number of comments are redundant, some outdated and others outright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

Note: xt_sctp.h is still not merged upstream in the kernel as of
this commit. But a refactoring was really needed.

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).
