Unique names 3/6
Give symbols of libxt matches unique names (2/3). 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). Signed-off-by: Jan Engelhardt <jengelh@gmx.de>
