:param netshort: 16-bit short addr
:rtype: converted addr
Cache
-----
.. function:: storeQueryInCache(qstate, qinfo, msgrep, is_referral)
Store pending query in local cache.
:param qstate: :class:`module_qstate`
:param qinfo: :class:`query_info`
:param msgrep: :class:`reply_info`
:param is_referal: integer
:rtype: boolean
.. function:: invalidateQueryInCache(qstate, qinfo)
Invalidate record in local cache.
:param qstate: :class:`module_qstate`
:param qinfo: :class:`query_info`
Logging
-------
.. function:: verbose(level, msg)
Log a verbose message, pass the level for this message.
No trailing newline is needed.
:param level: verbosity level for this message, compared to global verbosity setting.

performs mallocs to do so, slow. But debug useful.
:param msg: string desc to accompany the hexdump.
:param data: data to dump in hex format.
:param length: length of data.
.. function:: log_dns_msg(str, qinfo, reply)
Log DNS message.
:param str: string message
:param qinfo: :class:`query_info`
:param reply: :class:`reply_info`
.. function:: log_query_info(verbosity_value, str, qinf)
Log query information.
:param verbosity_value: see constants
:param str: string message
:param qinf: :class:`query_info`
.. function:: regional_log_stats(r)
Log regional statistics.
:param r: :class:`regional`
Debugging
---------
.. function:: strextstate(module_ext_state)
Debug utility, module external qstate to string.
:param module_ext_state: the state value.
:rtype: descriptive string.
.. function:: strmodulevent(module_event)
Debug utility, module event to string.
:param module_event: the module event value.
:rtype: descriptive string.
