The Clang analyzer has trouble detecting that functions can never return
null in certain conditions, this results in several false "Dereference of
null pointer" detections.
This patch annotates functions that call ovsdb_error_valist()
unconditionally as non-null, as this function will either return a valid
pointer or call abort().

Add suport for ovsdb RBAC (role-based access control). This includes:
- Support for "RBAC_Role" table. A db schema containing a table
by this name will enable role-based access controls using
this table for RBAC role configuration.
The "RBAC_Role" table has one row per role, with each row having a
"name" column (role name) and a "permissions" column (map of
table name to UUID of row in separate permission table.) The
permission table has one row per access control configuration,
with the following columns:
"name" - name of table to which this row applies
"authorization" - set of column names and column:key pairs
to be compared against client ID to
determine authorization status
"insert_delete" - boolean, true if insertions and
authorized deletions are allowed.
"update" - Set of columns and column:key pairs for
which authorized updates are allowed.
- Support for a new "role" column in the remote configuration
table.
- Logic for applying the RBAC role and permission tables, in
combination with session role from the remote connection table
and client id, to determine whether operations modifying database
contents should be permitted.
- Support for specifying RBAC role string as a command-line option
to ovsdb-tool (Ben Pfaff).

Sometimes internal errors are generated based on an originating error. In
these cases we were just throwing this information away. This commit adds
this information to the internal error report so that the error will be
easier to track down.
I haven't actually seen a situation like this come up.
