Victor Julien d834173bb8 detect-flow: use dedicated flags 
The flow keyword used flag names that were shared with the
Packet::flowflags field. Some of the flags were'nt used by the packet
though. This lead to waste of some 'flag space'.

This patch defines dedicated flags for the flow keyword and removes
the otherwise unused flags from the FLOW_PKT_* space.

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.

Eric Leblond 6842545331 Add documentation url in list-keyword output. 
The output of the list-keyword is modified to include the url to
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.

Anoop Saldanha 855726f372 fix for bug #575. 
If sig has no_stream set, don't mask it as requiring flow.  Should get rid of
FNs any.

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
+ if (unlikely(x == NULL)) S1
