It may happen that the io-handler is still registered. That causes
select() to return with EBADF, not calling handlers for other fds.

The io-handler would be registered when (on the source) the whole state
was written but not yet flushed. For example when using QEMUFileBuffered,
(tcp-migration) there may be data left in a buffer waiting to be transferred.
In such a case buffered_close() calls buffered_flush() which calls
migrate_fd_put_buffer, which may, upon EAGAIN, register migrate_fd_put_notify
as a handler.

Sometimes, upon interrupt, fread returns with no data, and
the (incoming exec) migration fails.

Fix by retrying on such a case.

(patch is on top of "Apic creation should not depend on pci" series)

Currently cpu_index is used as cpu apic id on x86.  This is incorrect
since apic ids not have to be continuous (they can also encode cpu
hierarchy information). This patch uses cpuid_apic_id for initial apic id
value. For now cpuid_apic_id is set to be equal to cpu_index so behaviour
is fully backward compatible, but it allows us to add qemu option to
provide other values for cpu apic id.

SDL header files can be included in two different ways:

* like this: #include <SDL/SDL.h>
* like this: #include <SDL.h>

The 1st alternative is simple and works in many cases.

The 2nd alternative needs sdl-config to get the
correct compiler flags. It is the recommended way
to write SDL includes and standard for QEMU.

The patch fixes two non-standard SDL includes.

Needed for savevm/loadvm + migration: In that case the queue might
already have packets on (re-)connect.  The guest wouldn't notify us
because notifications are only sent when stuffing a packet into an
empty queue.

Type casts removing the const attribute are bad because
they hide the fact that the argument remains const.

They also result in a compiler warning (at least with MS-C).

The function qemu_calculate_timeout() is only used when CONFIG_IOTHREAD
is not defined. When CONFIG_IOTHREAD is defined, we have the following
warning:

vl.c:4389: warning: ‘qemu_calculate_timeout’ defined but not used

This change fixes that by moving the #ifdef/#endif from main_loop()
into qemu_calculate_timeout(). This encapsulates the logic and allow
us to use qemu_calculate_timeout() when CONFIG_IOTHREAD is defined
or not (suggested by Glauber Costa).
