Alex Bligh 40daca54cd aio / timers: Rearrange timer.h & make legacy functions call non-legacy
Rearrange timer.h so it is in order by function type.

Make legacy functions call non-legacy functions rather than vice-versa.

Convert cpus.c to use new API.

Alex Bligh ac70aafc28 aio / timers: Use all timerlists in icount warp calculations
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.

Markus Armbruster ba646ff6a3 qtest: Don't reset on qtest chardev connect
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.

Peter Maydell 56863d4f19 qtest: Handle addresses and values for {in, out}[bwl] as unsigned
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.

Anthony Liguori 0fbf01fe91 qtest: use synchronous I/O for char device
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.

Andreas Färber 5dd6be069b qtest: Use strtoull() for uint64_t
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.

Anthony Liguori c7f0f3b1c8 qtest: add test framework
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.
