+ * @brief Adaptive delay buffer with high-quality time-scale
+ * modification
+ * @{
+ *
+ * This section describes PJMEDIA's implementation of delay buffer.
+ * Delay buffer works quite similarly like a fixed jitter buffer, that
+ * is it will delay the frame retrieval by some interval so that caller
+ * will get continuous frame from the buffer. This can be useful when
+ * the put() and get() operations are not evenly interleaved, for example
+ * when caller performs burst of put() operations and then followed by
+ * burst of get() operations. With using this delay buffer, the buffer
+ * will put the burst frames into a buffer so that get() operations
+ * will always get a frame from the buffer (assuming that the number of
+ * get() and put() are matched).
+ *
+ * The buffer is adaptive, that is it continuously learns the optimal delay
+ * to be applied to the audio flow at run-time. Once the optimal delay has 
+ * been learned, the delay buffer will apply this delay to the audio flow,
+ * expanding or shrinking the audio samples as necessary when the actual
+ * audio samples in the buffer are too low or too high. It does this without
+ * distorting the audio quality of the audio, by using \a PJMED_WSOLA.
+ *
+ * The delay buffer is used in \ref PJMED_SND_PORT, \ref PJMEDIA_SPLITCOMB,
+ * and \ref PJMEDIA_CONF.

+/**
+ * @defgroup PJ_DNS_RESOLVER DNS Asynchronous/Caching Resolution Engine
+ * @ingroup PJ_DNS
+ * @{
+ *
+ * This module manages the host/server resolution by performing asynchronous
+ * DNS queries and caching the results in the cache. It uses PJLIB-UTIL 
+ * low-level DNS parsing functions (see @ref PJ_DNS) and currently supports
+ * several types of DNS resource records such as A record (typical query with
+ * gethostbyname()) and SRV record.
+ *
+ * \section PJ_DNS_RESOLVER_FEATURES Features
+ *
+ * \subsection PJ_DNS_RESOLVER_FEATURES_ASYNC Asynchronous Query and Query Aggregation
+ * 
+ * The DNS queries are performed asychronously, with timeout setting 
+ * configured on per resolver instance basis. Application can issue multiple
+ * asynchronous queries simultaneously. Subsequent queries to the same resource
+ * (name and DNS resource type) while existing query is still pending will be
+ * merged into one query, so that only one DNS request packet is issued.
+ * 
+ * \subsection PJ_DNS_RESOLVER_FEATURES_RETRANSMISSION Query Retransmission
+ *
+ * Asynchronous query will be retransmitted if no response is received
+ * within the preconfigured time. Once maximum retransmission count is
+ * exceeded and no response is received, the query will time out and the
+ * callback will be called when error status.
+ *
+ * \subsection PJ_DNS_RESOLVER_FEATURES_CACHING Response Caching with TTL
+ *
+ * The resolver instance caches the results returned by nameservers, to
+ * enhance the performance by minimizing the message round-trip to the server.
+ * The TTL of the cached resposne is calculated from minimum TTL value found 
+ * across all resource record (RR) TTL in the response and further more it can
+ * be limited to some preconfigured maximum TTL in the resolver. 
+ *
+ * Response caching can be  disabled by setting the maximum TTL value of the 
+ * resolver to zero.
+ *
+ * \subsection PJ_DNS_RESOLVER_FEATURES_PARALLEL Parallel and Backup Name Servers
+ *
+ * When the resolver is configured with multiple nameservers, initially the
+ * queries will be issued to multiple name servers simultaneously to probe
+ * which servers are not active. Once the probing stage is done, subsequent 
+ * queries will be directed to only one ACTIVE server which provides the best
+ * response time.
+ *
+ * Name servers are probed periodically to see which nameservers are active
+ * and which are down. This probing is done when a query is sent, thus no
+ * timer is needed to maintain this. Also probing will be done in parallel
+ * so that there would be no additional delay for the query.
+ *
+ *
+ * \subsection PJ_DNS_RESOLVER_FEATURES_REC Supported Resource Records
+ *
+ * The low-level DNS parsing utility (see @ref PJ_DNS) supports parsing of
+ * the following DNS resource records (RR):
+ *  - DNS A record
+ *  - DNS SRV record
+ *  - DNS PTR record
+ *  - DNS NS record
+ *  - DNS CNAME record
+ *
+ * For other types of record, application can parse the raw resource 
+ * record data (rdata) from the parsed DNS packet (#pj_dns_parsed_packet).
+ *
+ *
+ * \section PJ_DNS_RESOLVER_USING Using the Resolver
+ *
+ * To use the resolver, application first creates the resolver instance by
+ * calling #pj_dns_resolver_create(). If application already has its own
+ * timer and ioqueue instances, it can instruct the resolver to use these
+ * instances so that application does not need to poll the resolver 
+ * periodically to process events. If application does not specify the
+ * timer and ioqueue instance for the resolver, an internal timer and
+ * ioqueue will be created by the resolver. And since the resolver does not
+ * create it's own thread, application MUST poll the resolver periodically
+ * by calling #pj_dns_resolver_handle_events() to allow events (network and 
+ * timer) to be processed.
+ *
+ * Next, application MUST configure the nameservers to be used by the
+ * resolver, by calling #pj_dns_resolver_set_ns().
+ *
+ * Application performs asynchronous query by submitting the query with
+ * #pj_dns_resolver_start_query(). Once the query completes (either 
+ * successfully or times out), the callback will be called.
+ *
+ * Application can cancel a pending query by calling #pj_dns_resolver_cancel_query().
+ *
+ * Resolver must be destroyed by calling #pj_dns_resolver_destroy() to
+ * release all resources back to the system.
+ *
+ *
+ * \section PJ_DNS_RESOLVER_LIMITATIONS Resolver Limitations
+ *
+ * Current implementation mainly suffers from a growing memory problem,
+ * which mainly is caused by the response caching. Although there is only
+ * one cache entry per {query, name} combination, these cache entry will
+ * never get deleted since there is no timer is created to invalidate these
+ * entries. So the more unique names being queried by application, there more
+ * enties will be created in the response cache.
+ *
+ * Note that a single response entry will occupy about 600-700 bytes of 
+ * pool memory (the PJ_DNS_RESOLVER_RES_BUF_SIZE value plus internal
+ * structure). 
+ *
+ * Application can work around this problem by doing one of these:
+ *  - disable caching by setting PJ_DNS_RESOLVER_MAX_TTL and 
+ *    PJ_DNS_RESOLVER_INVALID_TTL to zero.
+ *  - periodically query #pj_dns_resolver_get_cached_count() and destroy-
+ *    recreate the resolver to recycle the memory used by the resolver.
+ *
+ * Note that future improvement may solve this problem by introducing 
+ * expiration timer to the cached entries.
+ *
+ *
+ * \section PJ_DNS_RESOLVER_REFERENCE Reference
+ *
+ * The PJLIB-UTIL resolver was built from the information in the following
+ * standards:
+ *  - <A HREF="http://www.faqs.org/rfcs/rfc1035.html">
+ *    RFC 1035: "Domain names - implementation and specification"</A>
+ *  - <A HREF="http://www.faqs.org/rfcs/rfc2782.html">
