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
Introduce SpiceMarshaller param to all send's that do add_buf
Next patch will use marshaller in all functions that currently don't by
replacing red_channel_add_buf with marshaller add_ref. Note - currently
tunnel is broken due to wrong size in messages.
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).
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.

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.
Remove all uses of @end in the marshaller, instead just using
the C struct array-at-end-of-struct. To make this work we also remove
all use of @end for switches (making them C unions).
We drop the zero member of the notify message so that we can avoid this
use of @end for a primitive in the marshaller (plus its useless to send
over the wire).
We change the offsets and stuff in the migration messages to real pointers.
