api: string type to convert to vector
Previous use of strndup() required user to remember to call free(). Now return a vector pointing directly to the API message string. Of course user must remember to copy the string out if lifetime is longer than API message lifetime. Change-Id: Ib5e2b3d52d258e1a42ea9ea9a9e04abbe360e2bf Type: fix Signed-off-by: Ole Troan <ot@cisco.com>
