Parses a list of {@link Function function} definitions from xml and creates then, adding them to the current
{@link Program program}.
<p>
Information from a TYPEINFO_COMMENT is used in preference to information from RETURN_TYPE and STACK_FRAME/STACK_VARs that
are tagged as parameters.
<p>
DTD for the FUNCTION element:
<pre><code>
&lt;!ELEMENT FUNCTION (RETURN_TYPE?, ADDRESS_RANGE*, REGULAR_CMT?, REPEATABLE_CMT?, TYPEINFO_CMT?, STACK_FRAME?, REGISTER_VAR*)&gt;
</code></pre>

@param overwriteConflicts true to overwrite any conflicts
@param ignoreStackFrames true to ignore stack frames
@param monitor the task monitor
@throws AddressFormatException if any address is not parsable
