0.31.0

[ssilverman]

Added

• Added qnethernet_hal_fill_entropy(buf, size) for filling a buffer with random values.
• Added EthernetClient::setConnectionTimeoutEnabled(flag) to enable or disable blocking with calls to connect(...) and stop(). This supersedes calls to connectNoWait(...) and close(). Also added isConnectionTimeoutEnabled().
• Added templated versions of util::writeFully() and util::writeMagic() that use a break function that static_casts a given object to a bool.
• Added EthernetClient::connecting() for determining if the client is still in the process of connecting during a non-blocking connect.

Changed

• Remove internal uses of String from MDNSClass and replace them with char arrays.
• Updated Mbed TLS version mentions to 2.28.9 from 2.28.8.
• Made EthernetClient::isNoDelay() const.
• Disallow compilation for Teensyduino < 1.59 because there's no support for casting a const IPAddress to a uint32_t or for equality-comparing them.
• Replaced EthernetClient::writeFully(const char *, size_t) and writeFully(const uint8_t *, size_t) with writeFully(const void *, size_t).
• Updated the file structure to put most sources underneath src/qnethernet/.
• Changed EthernetClient::setConnectionTimeout(timeout) and connectionTimeout() to use 32-bit values.
• Renamed qnethernet_hal_rand() and qnethernet_hal_init_rand() to qnethernet_hal_entropy() and qnethernet_hal_init_entropy(), respectively.
• Changed the non-entropy version of the entropy functions in the HAL to use std::minstd_rand instead of std::rand() and std::srand().
• Changed uses of "www.example.com" to "www.google.com" in the examples and tests.

Fixed

• Now using (void) instead of () for all C function declarations because () doesn't mean "no parameters" in C.
• Fixed driver_unsupported's driver_init(void) parameters to be empty.
