Unique names 2/6
Give symbols of libxt targets 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).
