Implemented async callbacks to PHP regardless of thread model, Sigv4 signing (#24)
* Updated to get latest aws-crt-ffi * Added implementation for signing_result * Added main thread queue and callback queueing to signing process * Updated to get support for date on signing_config_aws * added date support to SigningConfigAWS, fixed up reference issues on http message signing * Broke C code into separate files, moved common stuff to php_aws_crt.h * Use a unity build to make PHP do the right thing with our lib * Updated aws-crt-ffi to v0.1.3 to get sigv4 changes * Added CRT::isAvailable for safe runtime detection of CRT * Fixed up test resource safety, added tests to prove it * Added CI jobs for every version of PHP on linux (#26)
