Make the RedsState object own an InputsChannel object rather than
having a global inputs channel. This means changing a lot of
inputs-related API to take an InputsChannel* argument and moving the
keyboard, mouse, and tablet objects into the InputsChannel object.

This patch and previous ones want to solve the problem of not having a
context in SpiceCoreInterface. SpiceCoreInterface defines a set of
callbacks to handle events in spice-server. These callbacks allow to
handle timers, watch for file descriptors and send channel events.
All these callbacks do not accept a context (usually in C passed as a
void* parameter) so it is hard for them to differentiate the interface
specified.
Unfortunately this structure is used even internally from different
contexts for instance every RedWorker thread has a different context. To
solve this issue some workarounds are used. Currently for timers a variable
depending on the current thread is used while for watches the opaque
parameter to pass to the event callback is used as it currently points just
to RedChannelClient structure. This however imposes some implicit
maintainance problem in the future. What happens for instance if for some
reason a timer is registered during worker initialization, run in another
thread? What if we decide to register a file descriptor callback for
something not a RedChannelClient? Could be that the program will run
without any issue till some bytes change and weird things could happen.
The implementation of this solution is done implementing an internal "core"
interface that has context specific and use it to differentiate the
context instead of relying on some other, hard to maintain, detail. Then an
adapter structure (name inpired to the adapter pattern) will provide the
internal core interface using the external, public, definition (in the
future this technique can be used to extend the external interface without
breaking the ABI).

Add wrapper functions for SpiceCoreInterface in order to present
a SpiceCoreInterfaceInternal. These functions just expect
SpiceCoreInterfaceInternal API and forward request to
SpiceCoreInterface.
This allows to change ABI details of internal one.

This is really not supported, requires X11, so better to remove it for

spice_server_destroy calls reds_exit which is called also at exit time
(is registered with atexit) so avoid to keep dangling pointers.
Currently this does not happen as spice_server_destroy is not called
by Qemu.

This has been renamed to SpiceImageCompression in order to avoid clashes
with older spice-server in the SPICE_IMAGE_COMPRESS_ namespace. This
commit is a straight rename of SpiceImageCompress to
SpiceImageCompression and SPICE_IMAGE_COMPRESS_ to
SPICE_IMAGE_COMPRESSION_
If a previous Qemu executable is not able to delete the statistic file
on the next creation with same name (statitics file are based on pid
numbers so if pid get reused for another Qemu process you get the same
name) it fails as you can't open a file with 0444 permissions (these
are the permission used to create these files).
This patch assure there are no stale file trying to remove it before the
creation of the new one. As file is based on pid and name used for spice
you are not deleting another file.

With a TCP socket, the backlog doesn't seem to matter much,
perhaps because of latency or underlying protocol behaviour. However,
on UNIX socket, it is fairly easy to reach the backlog limit and the
client will get an EAGAIN error (but not ECONNREFUSED as stated in
listen(7)) that is not easy to deal with: attempting to reconnect in a
loop might busy-loop forever as there are no guarantee the server will
accept new connections, so it will be inherently racy.
Typically, Spice server can easily have up to 15 concurrent incoming
connections that are established during initialization of the session.
To improve the situation, raise the backlog limit to the default maximum
system value, which is 128 on Linux.
There is already a enumeration in a public header that defines the
different streaming options, so there's no need to duplicate that
enumeration internally. Just use the public enum values.
This commit fixes enough endianness issues that it's possible to
connect to a spice-server/qemu running on a big-endian box with a client
running on a little-endian machine.
I haven't tested more than getting to the bios/bootloader and typing a
bit on the keyboard as I did not manage to boot a distro afterwards :(
