vapi: implement vapi_wait() for reads
Type: improvement The function vapi_wait() is intended to allow a caller to block while waiting until the API queue can be read/written. It was a stub that returned VAPI_ENOTSUP. Add code which implements the wait on being able to read an incoming message. Had to touch a few other things in vapi.h to make checkstyle.sh happy after changing the prototype of vapi_wait().
