Log:
[PATCH 12/13] Unique symbols 6/6

Give symbols of libxt targets unique names (3/3).

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).
