/*! Call single backend statedata callback /*! Call single backend statedata callback

* Create an xml state tree (xret) for one callback only on the form:
* <config>...</config>,
* call a user supplied function (ca_statedata) which can do two things:
* - Fill in state XML in the tree and return 0
* - Call cli_error() and return -1
* In the former case, this function returns the state XML tree to the caller (which
* typically merges the tree with other state trees).
* In the latter error case, this function returns 0 (invalid) to the caller with no tree
* If a fatal error occurs in this function, -1 is returned.
