Subject: [PATCH] Move the ability to load the dasync engine into ssltestlib.c

The sslapitest has a helper function to load the dasync engine which is
useful for testing pipelining. We would like to have the same facility
from sslbuffertest, so we move the function to the common location
ssltestlib.c
