According to the documentation drivers using this device should read
FB_SIZE before enabling the device to know what memory to map. This
would not work if we return 0 before enabled. The docs also mention
reading SVGA_REG_DEPTH but not writing it. (Only SVGA_REG_BITS_PER_PIXEL
can be written but we don't really support that either.)

Commit ac4119c (chardev: Use timer instead of bottom-half to postpone
open event, 2012-10-12) moved the alarm timer initialization to an earlier
point but failed to consider that it depends on qemu_init_main_loop.
Later, commit 1c53786 (vl: init main loop earlier, 2012-10-30) fixed
this, but left -daemonize in two different ways. First, timers need to
be reinitialized after forking. Second, the global mutex was being held
by the parent, and thus dropped after forking.
The first is now fixed using pthread_atfork. For the second part,
make sure that the global mutex is not taken before daemonization,
and similarly delay qemu_thread_self.

* bonzini/migr-coroutine:
migration: move process_incoming_migration to a coroutine
migration: handle EAGAIN while reading QEMUFile
migration: move qemu_fclose to process_incoming_migration
migration: close socket QEMUFile from socket_close
migration: xxx_close will only be called once
migration: use closesocket, not close

migration: clean up server sockets and handlers before invoking process_incoming_migration
migration: replace qemu_stdio_fd with qemu_get_fd

This will never happen right now (the assertion would fail). The
next patch will set the socket or pipe in non-blocking mode, thus
enabling this part of the code.
Coroutines can just stop whenever they want with qemu_coroutine_yield.
As soon as select tells the main loop that the migration stream is
readable, the coroutine is re-entered directly in qemu_get_buffer,
where it will read more data and pass it to the loading routines.

migrate_fd_cleanup will usually close the file descriptor via
buffered_file_close's call to migrate_fd_close. However, in the case
of s->file == NULL it is "inlining" migrate_fd_close (almost: there is a
direct close() instead of using s->close(s)). To fix the inconsistency
and clean up the code, allow multiple calls to migrate_fd_close and use
the function in migrate_fd_cleanup.

This fixes the following:
target-i386/cpu.o: In function `kvm_cpu_fill_host':
target-i386/cpu.c:783: undefined reference to `kvm_state'
I didn't notice the problem before because GCC was optimizing the entire
kvm_cpu_fill_host() function out (because all calls are conditional on
kvm_enabled()).
* cpu_x86_fill_model_id() is used only if CONFIG_KVM is set, so #ifdef it
entirely to avoid compiler warnings.
* kvm_cpu_fill_host() should be called only if KVM is enabled, so
use #ifdef CONFIG_KVM around the entire function body.
