Since commit a2ce7dbd91 ("meson: convert tests/qtest to meson"),
libqtest.h is under libqos/ directory, while libqtest.c is still in
qtest/. Move back to its original location to avoid mixing with libqos/.

In the glib API, the distinction between g_assert() and
g_assert_true() is that the former is for "bug, terminate the
application" and the latter is for "test check, on failure either
terminate or just mark the testcase as failed". For QEMU, g_assert()
is always fatal, so code can assume that if the assertion fails
execution does not proceed, but this is not true of g_assert_true().
In npcm7xx_pwm-test, the pwm_index() and pwm_module_index() functions
include some assertions that are just guarding against possible bugs
in the test code that might lead us to out-of-bounds array accesses.
These should use g_assert() because they aren't part of what the test
is testing and the code does not correctly handle the case where the
condition was false.
This fixes some Coverity issues where Coverity knows that
g_assert_true() can continue when the condition is false and
complains about the possible array overrun at various callsites.
Fixes: Coverity CID 1442340, 1442341, 1442343, 1442344, 1442345, 1442346

This patch adds testing of PWM fan RPMs in the existing npcm7xx pwm
test. It tests whether the MFT module can measure correct fan values
for a PWM fan in NPCM7XX boards.

[PMM: fixed format strings for printing uint64_t]
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
Fix potential overflow problem when calculating pwm_duty.
1. Ensure p->cmr and p->cnr to be from [0,65535], according to the
hardware specification.
2. Changed duty to uint32_t. However, since MAX_DUTY * (p->cmr+1)
can excceed UINT32_MAX, we convert them to uint64_t in computation
and converted them back to uint32_t.
(duty is guaranteed to be <= MAX_DUTY so it won't overflow.)

The pwm_qom_get function didn't free "response", which caused an indirect
memory leak. So use qobject_unref() to fix it.
