<ul>
<li>pua_dialoginfo: Implement callee_trying parameter in pua_dialoginfo which causes
a "Trying" state to be sent for both the caller and callee when
a new dialog is created.</li>
<li>presentity: Implement table locking for all routes through update_presentity in order
to avoid a number of different race conditions which resulted in
extraneous data being put into the presentity table.</li>
</ul>

<p>The latter change fixes a race condition which triggers more frequently due to the first... however I'm sure there are instances when it would trigger regardless of the first change.</p>
