Code generated for demarshallers define and declare some types and
functions.
However these types and functions are also declared separately in
other headers 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.

rename common/{client_demarshallers.h => demarshallers.h} (62%)
Changes since v1:
- use a single header instead of 2;
- add patches for spice-server and spice-gtk.
