When using config.h, it must be the very first include in all source
files since it contains #define that may change the compilation process
(eg libc structure layout changes when it's used to enable large file
support on 32 bit x86 archs). This commit adds it at the beginning
of all .c and .cpp files
spice client and spice server shares code from
common/{gdi,gl,sw}_canvas.[ch]. However, while most of the code is
shared, the server code wants a canvas compiled with
SW_CANVAS_IMAGE_CACHE defined while the client code wants a canvas
compiled with SW_CANVAS_CACHE.
The initial autotools refactoring didn't take that into account,
this is now fixed by this commit. After this commit, the canvas
files from common/ are no longer compiled as part of the
libspice-common.la convenience library. Instead, there are "proxy"
canvas source files in client/ and server/ which #include the
appropriate C files after defining the relevant #define for the
binary that is being built.
To prevent misuse of the canvas c files and headers in common/,
SPICE_CANVAS_INTERNAL must be set when including the canvas headers
from common/ or when building the c files from common/ otherwise
the build will error out.
Changes in display channel for a code size win.
A note about this and the previous cursor change: it will appear that we are
now (with these changes) releasing resources too early. This is not so - send
always has the option of blocking, which means after send you can not release
resources anyway, that's what the release_item callback is for. So both the
code before and now are doing the same accounting.
Handling done in red_channel instead of per channel, using call backs
for the channel specific part.
Intended to reduce furthur reliance of channels on RedChannel struct.
The commit makes the code harder to understand because of the artificial
get_serial stuff, should later be fixed by having a joint migration
header with the serial (since all channels pass it).
For ussage in the send_item callback. It's only valid during this
time anyway (should make it return NULL in other occasions?)
No more direct usage of RedChannel.send_data.marshaller by channels.
The renames are part of refactoring red_worker's RedChannel to reuse
red_channel.h's RedChannel at the end.

This is stylish change again. We are talking about a RedStream object,
so let's just name the variable "stream" everywhere, to avoid
confusion with a non existent RedPeer object.

Adds RedChannel* channel as first parameter to hold_pipe_item_proc
with everything (almost) not in red_channel's RedChannel
As a result of CommonChannel a free cb is added to EventHandler,
to take care of non zero offset for embedded EventHandler.
hold_item called on init_send_data, matching release.
This is not the behavior of red_worker - we ref++ (==hold_item) when
sending the item, and --refs when releasing it, instead of only holding
if the send is blocked.
Note 1: Naming: hold_pipe_item is the proc name, the variable is called
hold_item, this is similar to release_item/release_pipe_item naming.
Note 2: All channels have empty implementation, we later use this when
red_worker get's RedChannelized.
