Graduality is irrelevant for A8 images, so instead of using RGB-ness
as a short-cut, add a new macro BITMAP_FMT_HAS_GRADUALITY() that
returns true for the existing RGB images, but false for A8.
This patch will replace the common/ directory with the spice-common
project. It is for now a simple project subdirectory shared with
spice-gtk, but the goal is to make it a proper library later on.
With this change, the spice-server build is broken. The following
commits fix the build, and have been seperated to ease the review.
v2
- moves all the generated marshallers to spice-common library
- don't attempt to fix windows VS build, which should somehow be
splitted with spice-common (or built from tarball only to avoid
generation tools/libs deps)
v3
- uses libspice-common-client
- fix a mutex.h inclusion reported by Alon
move all the ASSERT/PANIC/PANIC_ON/red_error/red_printf* macros
to a common file to be used with ring.h that is going to be used externally
(by spice-gtk).
We move all message structs from spice-protocol to spice as
we want to be able to change these as needed internally. The
on-network format is no longer defined by these structures anyway,
but rather by the spice protocol description.
