f19c9f9511 fix: the what names can treated as a condlistid
The match
  {VARIABLE_NAME}/{WS}*={WS}*\(

is too broad causing mount and dbus rules to fail for sets of values eg.

  mount options=(ro bind)

Instead of doing a broad match, for now lets lock it down to just
peer=(...) being the only cond that can cause entry into CONDLISTID

b222731c4f Add the ability to mediate signals.
Add signal rules and make sure the parser encodes support for them
if the supported feature set reports supporting them.

The current format of the signal rule is

  [audit] [deny] signal [<signal_perms>] [<signal_set>] <target_profile>,

  signal_perm  := 'send'|'receive'|'r'|'w'|'rw'
  signal_perms := <signal_perm> | '(' <signal_perm> ([,]<signal_perm>)* ')'
  signal := ("hup"|"int"|"quit"|"ill"|"trap"|"abrt"|"bus"|"fpe"|"kill"|
             "usr1"|"segv"|"usr2"|"pipe"|"alrm"|"term"|"tkflt"|"chld"|
             "cont"|"stop"|"stp"|"ttin"|"ttou"|"urg"|"xcpu"|"xfsz"|"vtalrm"|
             "prof"|"winch"|"io"|"pwr"|"sys"|"emt"|"exists")
  signal_set   := set=<signal> | '(' <signal> ([,]<signal>)* ')'


it does not currently follow the peer=() format, and there is some question
as to whether it should or not. Input welcome.
