Functions for obtaining existing parties, or phone numbers

Obtains a $service, $individual, or $telephone party, if available
$voiceTerminalBusy if party is a $telephone or $individual and corresponding $trunk is in use, or party is a $trunk and the corresponding $telephone is in use.
Except $success when ownParty is present and equals the corresponding party.  This represents an attempt to call one's own front door from the back or vice/versa, and is legal.
nb can take on other values if problems occur in obtaining the related party.
This is an Etherphone implementation-dependent thing -- front and back doors cannot be
in use for independent reasons at simultaneously -- and we are sore ashamed.
No active party; try to get a trunk line for that individual
Locates an idle $service party, if available
<<This still needs some work.>>
e.g., $"text-to-speech.lark"
e.g., $"myself.pa"
e.g., $"myself.pa.text-to-speech"
Party description has not yielded a party, so phone number will have to do.  Perhaps the phone number is an extension of an active $individual; if not, try to find an idle outgoing trunk.
myExt is used as Intelnet authorization code.
IF phoneNumber = NIL THEN RETURN[$noIdentSupplied, nullID];
A null phoneNumber is a request for a direct outside line connection.
Get Trunk Party
Making new parties and smartses

Deregister any previous smarts from this machine.  When cloning to produce multiple smarts and parties for a multi-channel service, obviously don't want to do this.
Multi-channel services must deregister explicitly, since this won't handle it.
Includes setting RName access, poaching and visiting designations.
rName is a misnomer; it's the name of a service, without registry, if type is service.
There's no voice path for this individual.  Try to create one using calling party's trunk.
Splice in poachees for poachers in any relationships that are ending, poachers for poachees in any that are beginning.
No HostForSmarts entry is made for clones.  What should happen here anyhow?

Deregister Smarts from Party, destroy both

There's but one party per smarts, these days.  When the Smarts goes, so goes the party.  For the most part, we can (after idling all the conversations in which the party participates) merely erase all the interconnections between the party and smarts and other objects, and release their ID's.
Don't hang up calls for $individual parties with valid poachees, since a poachee can carry on a conversation by itself.
$Visiting implementations and hints for implementations are only suggestions, for now.
Transfer $Visitors from authenticated to assumed.
Idle any conversations in which the party is involved.  Outside loop avoids Foreach/Erase conflicts.
Apply the process recursively to poachers and visitors: if a poacher is in a conversation, the poachee is not recorded as being in the same one; similarly for visitors, at least at present.  But the poachee or visitee is always vital to the conversation's existence, so out it goes.

This is still bogus.  It won't work as well as older systems at dealing properly with Finch dropping out.
