func_callerid: Document that CALLERID(pres) is available.

CALLERPRES() says that it's deprecated in favor of CALLERID(num-pres)
and CALLERID(name-pres).  But for channel driver that don't make a
distinction between the two (e.g. SIP), it makes more sense to get/set
both at once.  This change reveals the availability of CALLERID(pres),
CONNECTEDLINE(pres), REDIRECTING(orig-pres), REDIRECTING(to-pres) and
REDIRECTING(from-pres).

+ * CALLERID(pres) is now documented as a valid alternative to setting both
+   CALLERID(name-pres) and CALLERID(num-pres) at once.  Some channel drivers,
+   like chan_sip, don't make a distinction between the two: they take the
+   least public value from name-pres and num-pres.  By using CALLERID(pres)
+   for reading and writing, you touch the same combined value in the dialplan.
+   The same applies to CONNECTEDLINE(pres), REDIRECTING(orig-pres),
+   REDIRECTING(to-pres) and REDIRECTING(from-pres).
