Made PHP extension compile with openssl by default (#41)

* Made PHP extension compile with openssl

* Use catchsegv to dump a callstack

* Updated to use aws_crt_crypto_share()

* Much faster builds by making cmake parallel if supported

* Make sure all CRT threads shutdown prior to cleanup

* USE_OPENSSL should be the path to openssldir

* Updated to aws-crt-ffi v0.2.4
