Make the role conversions from AtkRole to Accessibility_Role and AccessibleRole

(from ATK, libspi-IDL, and CSPI) robust.  Added some roles used by ATK
to the at-spi role list.

+       * libspi/accessible.c:
+        Convert all AtkRole enumerations to Accessibility_Role enums when
+       getting a role from an AtkObject.
+       
+       * cspi/spi_accessible.c:
+       Complete the conversion of Accessibility_Role enums at runtime to
+       AccessibleRole (SPI_ROLE_*) roles in Accessible_getRole, so that
+       role enums correctly match those given in spi-roletypes.h.  
+       Re-synchronize the local names list for AccessibleRole_getName ().
+       AccessibleRole_getName is now deprecated, since it duplicates the
+       more reliable Accessible_getRoleName.
+       Added some role types from Accessibility_Role.idl.
+
+       * idl/Accessibility_Role.idl:
+       Added some role types used by AtkRole.
