/*
* Returns a new instance of an LDM proxy. Can take a while because it

*
* Arguments:
* host Identifier of the host on which an LDM server is
* running.
* instance Pointer to a pointer to the new instance. "*instance"
* is set upon successful return.
* Returns:
* 0 Success. "*instance" is set.
* LP_SYSTEM System error. "log_start()" called.
* LP_TIMEDOUT Connection attempt timed-out. "log_start()" called.
* LP_HOSTUNREACH Host is unreachable. "log_start()" called.
* LP_RPC_ERROR RPC error. "log_start()" called.
* LP_LDM_ERROR LDM error. "log_start()" called.
