Victor Julien 43b5234055 detect/priority: use global define for default prio 6 years ago
Victor Julien 954c43daf4 detect/classtype: allow undefined classtypes 
Effect of classification on Suricata's working is minimal. Impact
of adding undefined classtypes is large: rules will fail to load
completely. This also leads multiple lines of log output per rule,
which in a large ruleset can lead to excessive output.

This patch changes the classtype keyword behavior. Instead of erroring
and invalidating a rule, we will merely warn.

The undefined classtype is then defined with a default priority,
so other rules using the classtype will not also warn. This way
there will be just a single warning per missing classtype.

Victor Julien 323a747f39 classtype: increase id size 
Switch from u8 to u16 to allow for more classtypes.

Rename Signature::class to Signature::class_id to make it clear
it is an id.

Victor Julien a37e09cbe0 detect/classtype: change duplicate classtype behavior 
Detect duplicate instances and use the one with the highest
priority.

Use new priority flag to make the logic around explicit priority
sets easier to follow.

Minor code cleanups. Also clean up unittests.

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

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.
