77034bbc12 tests/qtest/npcm7xx_pwm-test: Be less verbose unless V=2
The npcm7xx_pwm-test produces a lot of output at V=1, which
means that on our CI tests the log files exceed the gitlab
500KB limit. Suppress the messages about exactly what is
being tested unless at V=2 and above.

This follows the pattern we use with qom-test.

d412597ec5 qtest/npcm7xx_pwm-test: Fix memory leak in mft_qom_set
g_strdup_printf() allocated memory for path, we should free it with
g_free() when no longer needed.

907b5105f1 tests: move libqtest.h back under qtest/
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/.

302585450c tests/qtest/npcm7xx_pwm-test.c: Avoid g_assert_true() for non-test assertions
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

999be4a2d3 tests/qtest: Test PWM fan RPM using MFT in PWM test
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.

1e5ce6e10a hw/misc: Fix arith overflow in NPCM7XX PWM module
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.)

3e829c0468 qtest/npcm7xx_pwm-test: Fix memleak in pwm_qom_get
The pwm_qom_get function didn't free "response", which caused an indirect
memory leak. So use qobject_unref() to fix it.

ASAN shows memory leak stack:
