	src/sys/arch/xen/include: ctrl_if.h intrdefs.h
	src/sys/arch/xen/xen: ctrl_if.c xencons.c

Log Message:
Add polling support to the domain controller. Use this in xencons instead
of relying on the fact that the domain controller is still getting interrupts
when xenconscn_getc()/xenconscn_putc() is called.
Now that polling is fixed, move IPL_CTRL down between IPL_SOFTSERIAL and
IPL_TTY, fixing port-xen/29999 by YAMAMOTO Takashi.
Now that IPL_CTRL is low enouth, remove the softintr stuff from the
domain controller, and call wakeup() directly.

Thanks to YAMAMOTO Takashi and Christian Limpach for feedback and suggestions.
