Keep cmake generated shared dbus-1 library file name in sync with autotools.

Browse source 
Autotools uses a versioned shared library name derived from libtool.
This patch adds a versioned shared library name to cmake builds for all
supported platforms. Binary compatibility for clients build against older
cmake generated binary packages of dbus is provided; on unix like os
with symbolic links and on Windows with a copy of the shared library.
