Impovements

• Refactor named task's implementation to make it faster.

Bug Fixes:

• Fix WFMySQLConnection crash bug when running multiple tasks concorrently.
• Fix kafka authentication bug by encoding for kafka SASL username and password.
• Fix kafka client bug that does not retry.

Incompatible changes

• Timed thread/go task's state in callback was changed to WFT_STATE_SYS_ERROR with error ETIMEDOUT when timeout. The original state was WFT_STATE_ABORTED. Please check timeout by using 'if (task->get_state() != WFT_STATE_SUCCESS)', which is compatible with both behaviors.
• Remove WFMultiThreadTask.

New Features

• Add watch_timeout for network task.

Improvements

• Optimize named timer's speed. About 3 times faster.
• Reduce light-weighted thread task's overhead.
• Optimize DNS resolving a lot. Reduce redundant DNS requests when querying a single host name parallelly.

• Enable setting specific SSL_CTX for each network task.
• WFMySQLConnection and WFKafkaClient enable setting a specific SSL_CTX.
• JSON parser adds 'json_value_copy()'.

Improvements

• More compatible with some rediculous HTTP server.
• Simplify Communicator's codes.
