Summary: dialog MI: from_tag is not optional for dlg_list

Initial Comment:
The documentation for the MI command 'dlg_list' states that 'from_tag' is optional. The function is useless without it because the hash is done over both 'callid' and 'from_tag', so without the 'from_tag' it is impossible to find a specific dialog.

The parameter should be required when callid is present.

Message:
The documentation should say something like that.
"WARNING: If the from_tag is not specified, only dialogs created by a
request without a from tag are matched, which will only occur with broken
clients and is thus a very rare situation."

Message:
The dialog module was design to be forgiving with old broken clients that
don't provide a from_tag.  This is the reason that the mi interface allows
NULL from_tag params.
