0.34.0

[ssilverman]

Added

• Added tests for some of the print utility functions and classes.
• Added the QNETHERNET_ENABLE_PING_REPLY macro to disable ICMP echo replies.
• Added a "Requirements" section listing some library requirements to the README.
• Added a QNETHERNET_PROVIDE_GNU_VERBOSE_TERMINATE_HANDLER configuration option for including our own version of __gnu_cxx::__verbose_terminate_handler for space-saving reasons.
• New StreamDecorator class that also does printf checking.
• Added driver_restart_auto_negotiation() driver function for restarting link auto-negotiation. This is useful for when EMF brings the link down. A new "EMF interference mitigation" section was also added to the Readme.
• Added qindesign::network::util::isBroadcast(ip, localIP, mask).
• New EthernetUDP::destIP() for getting the destination IP address from a received packet.

Changed

• Improved code style and structure.
• Made NullPrint::availableForWrite() return INT_MAX instead of zero.
• Changed EthernetUDP::stop() to not clear the current packet.
• Changed DNSClient::hostByName() functions to use a default value of QNETHERNET_DEFAULT_DNS_LOOKUP_TIMEOUT for the timeout parameter.
• Improved SimplePing example to catch DNS lookup errors.
• Changed ping send enable macro to QNETHERNET_ENABLE_PING_SEND from QNETHERNET_ENABLE_PING.
• Updated to support C++11 and C11 compilers.
• Improved setting of errno.
• Added printf checking to PrintDecorator.
• Replaced function-like-macros with static inline C functions.
• Renamed QNETHERNET_ENABLE_ALTCP_DEFAULT_FUNCTIONS macro to QNETHERNET_PROVIDE_ALTCP_DEFAULT_FUNCTIONS.
• EthernetUDP and EthernetFrame now share some common circular buffer code in an internal utility class.
• Replaced macros in EthernetClient with inline functions.

Fixed

• Fixed EthernetUDP internal packet clear to reset all variables.
• Now keeping any manually-set link UP state sticky so that the driver can choose not to set it to DOWN.
• Updated Ping and SimplePing examples to work with other systems by changing use of elapsedMillis to unsigned long plus calculations.
• Fixed ConnectionManager::iterateConnections() calls to not call Ethernet.loop() in the callback because that could potentially invalidate the iterator. Also added notes about potential iteration invalidation to the iterateConnections() and iterateListeners() docs.
• Fixed EthernetClient read() and peek() to return the correct value if not connected.
