target-arm: Don't handle c15_cpar changes via tb_flush()
At the moment we try to handle c15_cpar with the strategy of:
* emit generated code which makes assumptions about its value
* when the register value changes call tb_flush() to throw
away the now-invalid generated code
This works because XScale CPUs are always uniprocessor, but
it's confusing because it suggests that the same approach can
be taken for other registers. It also means we do a tb_flush()
on CPU reset, which makes multithreaded linux-user binaries
even more likely to fail than would otherwise be the case.
Replace it with a combination of TB flags for the access
checks done on cp0/cp1 for the XScale and iwMMXt instructions,
plus a runtime check for cp2..cp13 coprocessor accesses.

libqos: use microseconds instead of iterations for virtio timeout
Some hosts are slow or overloaded so test execution takes a long time.
Test cases use timeouts to protect against an infinite loop stalling the
test forever (especially important in automated test setups).
Commit
6cd14054b67774cc58a51fca6660cfa1d3c08059 ("libqos virtio:
Increase ISR timeout") increased the clock_step() value in an attempt to
lengthen the virtio interrupt wait timeout, but timeout failures are
still occuring on the Travis automated testing platform.
This is because clock_step() only affects the guest's virtual time.
Virtio requests can be bottlenecked on host disk I/O latency - which
cannot be improved by stepping the clock, so the fix was ineffective.
This patch changes the qvirtio_wait_queue_isr() and
qvirtio_wait_config_isr() timeout mechanism from loop iterations to
microseconds. This way the test case can specify an absolute 30 second
timeout. Number of loop iterations is not a reliable timeout mechanism
since the speed depends on many factors including host performance.
Tests should no longer timeout on overloaded Travis instances.

libqos: improve event_index test with timeout
The virtio event_index feature lets the device driver tell the device
how many requests to process before raising the next interrupt.
virtio-blk-test.c tries to verify that the device does not raise an
interrupt unnecessarily.
Unfortunately the test has a race condition. It spins checking for an
interrupt up to 100 times and then assumes the request has finished. On
a slow host the I/O request could still be in flight and the test would
fail.
This patch waits for the request to complete, or until a 30-second
timeout is reached. If an interrupt is raised while waiting the test
fails since the device was not supposed to raise interrupts.

qapi: add visit_start_union and visit_end_union
In some cases an input visitor might bail out on filling out a
struct for various reasons, such as missing fields when running
in strict mode. In the case of a QAPI Union type, this may lead
to cases where the .kind field which encodes the union type
is uninitialized. Subsequently, other visitors, such as the
dealloc visitor, may use this .kind value as if it were
initialized, leading to assumptions about the union type which
in this case may lead to segfaults. For example, freeing an
integer value.
However, we can generally rely on the fact that the always-present
.data void * field that we generate for these union types will
always be NULL in cases where .kind is uninitialized (at least,
there shouldn't be a reason where we'd do this purposefully).
So pass this information on to Visitor implementation via these
optional start_union/end_union interfaces so this information
can be used to guard against the situation above. We will make
use of this information in a subsequent patch for the dealloc
visitor.

virtio-balloon: fix integer overflow in memory stats feature

monitor: Reset HMP mon->rs in CHR_EVENT_OPEN
Commit
cdaa86a54 ("Add G_IO_HUP handler for socket chardev") exposed a bug in
the way the HMP monitor handles its command buffer. When a client closes the
connection to the monitor, tcp_chr_read() will detect the G_IO_HUP condition
and call tcp_chr_disconnect() to close the server-side connection too. Due to
the fact that monitor reads 1 byte at a time (for each tcp_chr_read()), the
monitor readline state / buffers might contain junk (i.e. a half-finished

tests: avoid running duplicate qom-tests
Since
3687d532 we've been unconditionally adding qom-test to our qtests
for every arch. However, some archs inherit their tests from Makefile
variables for other archs, such as i386/x86_64,
microblaze/microblazeel, and xtensa/xtensaeb. Since these are evaluated
in a lazy manner, we ultimately end up adding qom-test twice.
In the case x86_64, where we have a large number of machine types that
we rerun qom-test for, this has lead to a fairly noticeable increase
in the overall run-time of `make check` (78s vs. 42s on my machine).
Similar speed-ups are visible for other such archs, but not nearly as
significant.
Fix this by only adding qom-test to an arch's test list if it's not
already present.

trace: docs: add trace file description
When user used the trace print command from docs/tracing.txt:
./scripts/simpletrace.py trace-events trace-*
the user maybe be misled by the "trace-*", because if user
directly copy the comand line to run, there alway print the
bored message:
"usage: ./scripts/simpletrace.py <trace-events> <trace-file>"
then we should describe that the "trace-*" represented.
