optlen parameter of getsockopt() of type socklen_t* was read into
variable of type socklen_t, that caused zeroing out of upper 4 bytes
when running s390x on top of x86_64. This patch changes optlen type
to abi_ulong.

Use fprintf(stderr instead. This removes dependency of libqemuutil.a
on the monitor.

We can further justify this change, in that this code path should only
trigger under a fatal error condition. fprintf-stderr is probably the
appropriate medium as under a fatal error conidition the monitor itself
may be down and out for the count. So assertion failure messages should
go lowest common denominator - straight to stderr.

Fixes the build as reported by Kevin Wolf. Issue debugged and change
suggested by Luiz Capitulino. Issue introduced by
5d24ee70.

This patch uses inbound GPIO lines (IRQ and FIR) for
interrupts instead of using the old pic_cpu method,
which doesn't correspond to real hardware.

This creates the CPU's inbound IRQ and FIR GPIO lines and
updates the Microblaze boards to use this new method.
