Peter reported that rtc-test would periodically hang.  It turns out
this was due to an EAGAIN occurring on qemu_chr_fe_write.

Instead of heavily refactoring qtest, just use a synchronous version
of the write operation for qemu_chr_fe_write to address this problem.

Introduce [qtest_]{read,write}[bwlq]() libqtest functions and
corresponding QTest protocol commands to replace local versions in
libi2c-omap.c.

Also convert m48t59-test's cmos_{read,write}_mmio() to {read,write}b().

On 32-bit hosts, unsigned long may be uint32_t and uint64_t may be
unsigned long long. Account for this by always using strtoull().
We were already using strtoll() for int64_t.

Sparc Debian 5.0.8 does not define __suseconds_t as long,
but FMT_timeval expects %ld.

On linux, qemu_timeval will always be two long ints.  On windows, we use our
own struct definition.  This should fix win64.

This patch combines qtest and -icount together to turn the vm_clock
into a source that can be fully managed by the client.  To this end new
commands clock_step and clock_set are added.  Hooking them with libqtest
is left as an exercise to the reader.

Since /i440fx/piix3 is being removed from the composition tree, the
IO-APIC is placed under /i440fx.  This is wrong and should be changed
as soon as the /i440fx/piix3 path is put back.

The idea behind qtest is pretty simple.  Instead of executing a CPU via TCG or
KVM, rely on an external process to send events to the device model that the CPU
would normally generate.

qtest presents itself as an accelerator.  In addition, a new option is added to
establish a qtest server (-qtest) that takes a character device.  This is what
allows the external process to send CPU events to the device model.

qtest uses a simple line based protocol to send the events.  Documentation of
that protocol is in qtest.c.

I considered reusing the monitor for this job.  Adding interrupts would be a bit
difficult.  In addition, logging would also be difficult.

qtest has extensive logging support.  All protocol commands are logged with
time stamps using a new command line option (-qtest-log).  Logging is important
since ultimately, this is a feature for debugging.
