Code generated for demarshallers define and declare some types and
functions.
However these types and functions are also declared separately in other
headers (currently spice-common/client_demarshallers.h and
spice/server/demarshallers.h) resulting in potential ABI mismatch if the
different declarations do not match.
Using a common header shared between generated code and code using
these functions prevent potentially multiple different declarations.

The idea in version 1 of the protocol was to extend it using the minor
version. However this was replaced by the usage of capabilities and the
minor attribute (which was not much used in version 1) was abandoned in
version 2.
This patch create a big difference in the code generated but only because
the minor version was passed between all possible functions as argument.
Note that exported functions retain the minor argument for compatibility
reasons.
The demarshaller code export directly spice_get_client_channel_parser or
spice_get_server_channel_parser functions which returns internal module
functions which parse message of specific channels.

When building either spice-server or spice-gtk, spice-common should

test-overflow was doing a specific test on demarshalling code.
Joining the 2 tests also allows to remove the dependency from the main
protocol allowing to run the test independently from generation setting.
