Notify all timerlists derived from vm_clock in icount warp
calculations.

When calculating timer delay based on vm_clock deadline, use
all timerlists.

For compatibility, maintain an apparent bug where when using
icount, if no vm_clock timer was set, qemu_clock_deadline
would return INT32_MAX and always set an icount clock expiry
about 2 seconds ahead.

NB: thread safety - when different timerlists sit on different
threads, this will need some locking.

libqtest's qtest_init() connecting to the qtest socket triggers reset.
This was coded in the hope we could use the same QEMU process for
multiple tests that way.  Never used.  Injects an extra reset even
when it's not used, and that can mess up tests such as the one of
-boot once I'm about to add.  Drop it.

Handle the addresses and values for {in,out}[bwl] as unsigned (ie
with strtoul), as per the protocol specification comment. This fixes
a test failure in test_i440fx_defaults on 32-bit hosts where the test
tries to write 0x80000000 and qtest was instead writing 0x7fffffff.

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.

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

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.
