* Description (aclErrorFmt)

* This function formats an ACL error message into a buffer provided

* list structure. The caller can indicate how many error frames

* different error frames. The error frames on the error list are
* all freed, regardless of the maximum depth for traceback.
*

*
* errp - error frame list pointer
* msgbuf - pointer to error message buffer
* maxlen - maximum length of generated message
* maxdepth - maximum depth for traceback
