rabbitmq-c v0.9.0

Added:

• amqp-publish: added support for specifying headers via the -H flag
• Add support for specifying timeout for amqp_login calls via
  amqp_set_handshake_timeout
• Add support for specifying timeouts in RPC-style AMQP methods via
  amqp_set_rpc_timeout
• Add define for AMQP_DEFAULT_VHOST
• Support for SSL SNI
• Support for OpenSSL v1.1.0

Changed:

• rabbitmq-c now requires Windows Vista or better
• rabbitmq-c enables TCP keep-alive by default on platforms that support it
• dropped support for compiling rabbitmq-c without threading support
• OpenSSL is no longer un-intialized automatically by default. OpenSSL can be
  explicitly initialized by calling amqp_initialize_ssl_library and
  uninitialized by calling amqp_uninitialize_ssl_library.

Fixed:

• Correct bugs in processing of --url flag in tools (#364).
• Improve documentation on AMQP_SASL_METHOD_EXTERNAL (#349)
• Improve support for compiling under mingw-w64
• Better support for handing SIGPIPE on Linux over SSL (#401)
• Improve publish performance on Linux by not specifying MSG_MORE on last part
  of message.
• Fix connection logic where multiple hostnames won't be tried if connection to
  doesn't fail immediately (#430)

Removed:

• autotools build system has been removed
• many duplicate amqps_* examples, they did not add a lot of value
