Replace poll call with select.
As socket is set to non-blocking we must support it so if
we detect an EAGAIN error wait for data.

The only way to add new message to Dispatcher was to register
using a number. These numbers corresponded to array indexes.
This is good if the list of messages is allocated statically
and contiguously, on the contrary this method is not that
flexible.
Writing a header of 4 or 16 bytes using system call does not
make much difference so pass all message information in the
payload header.
A new dispatcher_send_message_custom function allows to send
a message passing all message information, including the
pointer to the handler.
This will allow for instance a Dispatcher associate to a given
thread to be reused by different classes.

The remaining occurrences of spice_printerr() are warnings when
something unexpected happens, they can be replaced with g_warning() so
that users of spice-server can redirect them with
g_log_set_default_handler().

This callback was only executed for message types that were registered
with DISPATCHER_ASYNC ack type. However, the async_done handler was
called immediately after the message-specific handler and was called in
the same thread, so the async_done stuff can just as easily be done from
within the message-specific handler. This allows to simplify the
dispatcher_register_handler() method to simply require a boolean
argument for whether the message type requires an ACK or not.

Although dispatcher_send_message() does not allow you to send a message
type that is invalid for a dispatcher, it still makes sense to verify
that the type is valid in the receiver. This should only be possible in
the case of some severe problem such as memory corruption, so if it is
invalid, we simply abort.

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

used for main_dispatcher only in this patch.
Dispatcher is meant to be used for Main<->any low frequency messages.
It's interface is meant to include the red_dispatcher usage:
fixed size messages per message type
some messages require an ack
Some methods are added to be used by RedDispatcher later:
dispatcher_handle_read - to be called directly by RedDispatcher epoll
based loop
dispatcher_set_opaque - to be set from red_worker pthread
dispatcher_init - allow NULL core as used by red_worker
Read and Write behavior:
Sender: blocking write, blocking read for ack (if any).
Reader: poll for any data, if such then blocking read for a
message_type and following message. repeat until poll returns
with no pending data to read.
