payload buffer datatypes are consistent
The 'data' parameter to nfq_get_payload() returns pointer to unsigned
char (rather than signed char) to make it consistent with the 'buf'
parameter of nfq_set_verdict(), nfq_set_verdict2(), and
nfq_set_verdict_mark(), all of which refer to the same data. Either
signed or unsigned is fine, but they should be consistent as the output
of nfq_get_payload() may be passed back into nfq_set_verdict*(); in that
case, this change eliminates the need for typecasting in the calling
code when using compilers that enforce strict typecasting.

non-modified payload arguments are pointer-to-const
The payload parameters to nfq_set_verdict(), nfq_set_verdict2(), and
nfq_set_verdict_mark() are not modified by those functions, and
therefore should have datatype pointer-to-const. This both causes the
source-code to more effectively represent what is the purpose of the
parameter, and eliminates the need to cast away const-ness when calling
the functions with compilers that enforce strict casting. All existing
calling code should not need modification as pointer-to-X automatically
converts to pointer-to-const-X.

nfq: deprecate nfq_set_verdict_mark() in favour of nfq_set_verdict2()
This patch deprecates nfq_set_verdict_mark() in favour of
nfq_set_verdict2() which does exactly the same but it also
convert the mark value from host-byte order to network-byte
order as expected by nfnetlink_queue.
I know, this is hackish, but I prefer adding new functions
instead of API versioning which is also ugly.
