Victor Julien e85a44c383 suppress: support ip-lists 
Ticket: 1137

Support supplying a list of IP's to the suppress keyword. Variables from
the address-groups and negation is supported. The same logic (and code) is
used that is also used in parting the IP portions of regular detection
rules.

Victor Julien bc2b53f10b parsing: s/strtok/strtok_r/g 
Remove all strtok uses and replace them by strtok_r.

Do the same for Windows builds. Cygwin builds fine with strtok_r.

Add strtok to banned function list.

Ken Steele 923a77e952 Change Match() function to take const SigMatchCtx* 
The Match functions don't need a pointer to the SigMatch object, just the
context pointer contained inside, so pass the Context to the Match function
rather than the SigMatch object. This allows for further optimization.

Change SigMatch->ctx to have type SigMatchCtx* rather than void* for better
type checking. This requires adding type casts when using or assigning it.

The SigMatch contex should not be changed by the Match() funciton, so pass it
as a const SigMatchCtx*.

Ken Steele 8f1d75039a Enforce function coding standard 
Functions should be defined as:

int foo(void)

}

Rather than:
int food(void) {
}

All functions where changed by a script to match this standard.

the keyword documentation when this is available. All documented
keywords should have their link set.

list-keyword can be used with an optional value:
 no option or short: display list of keywords
 csv: display a csv output on info an all keywords
 all: display a human readable output of keywords info
 $KWD: display the info about one keyword.

Eric Leblond e176be6fcc Use unlikely for error treatment. 
When handling error case on SCMallog, SCCalloc or SCStrdup
we are in an unlikely case. This patch adds the unlikely()
expression to indicate this to gcc.

This patch has been obtained via coccinelle. The transformation
is the following:

@istested@
identifier x;
statement S1;
identifier func =~ "(SCMalloc|SCStrdup|SCCalloc)";
@@

x = func(...)
... when != x
- if (x == NULL) S1
