Request backport to xen qemu-upstream gits of a fix that solves occasional qemu crash using spice

[Fabio Fantoni]

On production system using xen 4.5 I had occasional qemu crash using 
spice, from qemu log:
> qemu-system-i386: spice-qemu-char.c:173: spice_chr_add_watch: 
> Assertion `cond == G_IO_OUT' failed.
It was solved upstream with this patch:
http://git.qemu.org/?p=qemu.git;a=commitdiff;h=f7a8beb5e6a13dc924895244777d9ef08b23b367
I already applied it on 2 my systems with xen>=4.5 without find regressions.
It is a small patch that affect only users that use spice solving an 
occasional qemu using spice, so I think is good backport it to 
qemu-upstream-unstable.git and qemu-upstream-4.5-testing.git.
On qemu-upstream-4.4-testing.git and older is not needed because they 
have older qemu without patch that introduced the regression ("serial: 
poll the serial console with G_IO_HUP").

Thanks for any reply and sorry for my bad english.

Done. Thanks for pointing it out!
