Several functions in server/ were not specifying an argument list,
ie they were declared as void foo(); When compiling with
-Wstrict-prototypes, this leads to:
test_playback.c:93:5: erreur: function declaration isn’t a prototype
[-Werror=strict-prototypes]
When compiling spice with make CFLAGS="-g3 -ggdb3 -O0 -Wall -Werror",
the build broken because of a few unused variables/missing returns.
This patch fixes these warnings.
updates taken from spice vga mode updates, i.e. non cacheable, glz compressed
(depends on whatever settings you apply to the server) opaque draw operations.
+ completed the SpiceCoreInterface implementation (timers)
v1->v2:
removed test_util.c (Hans)
replaced mallocz with calloc (Hans)
