* rename cdbus header include guards to use CDBUS_ instead of LASH_DBUS_
* remove dbus/error.h and dbus/error.c
error.h contained lash/ladish specific error strings and
lash_dbus_error() prototype. lash_dbus_error() is renamed to
cdbus_error() and its implementation is moved to dbus/method.c. The
D-Bus error strings that have DBUS_ERROR_XXX matches are removed and
their uses are switched to the libdbus variants. The ladish specific
error strings are moved to dbus_constants.h
* Room creation/destruction is now separeted from starting/stopping
(creating/destroying jmcore links)
* Rooms can now be created and destryed when studio is stopped
* Rooms are started/stopped when studio is started/stopped
Apart from better interraction of studio start/stop and room
lifecycles, it is now possible to implement load of studio with rooms
because during studio load rooms have to be created in stopped state
and eventually started only at later stage, during studio start.
