CallManager, ConfigurationManager and ContactManager dbus APIs.

These files are generated by dbus-binding-tool using the server's files named *-introspec.xml:
  * dbus-binding-tool --mode=glib-client "../../../src/dbus/callmanager-introspec.xml" > callmanager-glue.h
  * dbus-binding-tool --mode=glib-client "../../../src/dbus/configurationmanager-introspec.xml" > configurationmanager-glue.h
  * dbus-binding-tool --mode=glib-client "../../../src/dbus/contactmanager-introspec.xml" > contactmanager-glue.h

These files dbus call wrapper functions to simplify access to dbus API.


UPDATE: These files, and { marshaller.c, marshaller.h } are now created by the build system at the compilation time
