Only run a test automatically if the Python test script is executed
directly. This will allow importing tests as modules in a test runner.

If CRC support isn't available (most likely caused by debugfs not being
mounted), the CRCReader constructor will throw an exception that the crc
test doesn't handle. Move construction of the CRCReader earlier and skip
the test if it fails.

Use formatted string literals to replace legacy printf-style string
formatting.

The code base mixes single and double quotes. Standardize on single
quotes except for triple-quoted strings (to match the PEP8 coding style)
and where the string contains single quotes to avoid the need to escape
them.

Instead of only checking that the CRC value is constant, compute the
expected CRC value, and compare it to the hardware-generated CRC.

The Composer gathers the computation of planes position. It is currently
only used to configure the planes.

The CRTC should be disabled when the test completes, regardless of
whether it succeeds or fails.

Commit 3cd7e6814cea ("kmstest.py: Fix CRTC disabling") modified the CRC
test to use the kmstest.AtomicRequest class, but failed to pass the
correct argument to the constructor. Fix it.

Add a generator method to the KMSTest class to enumerate all
non-writeback connectors, and use it through tests.

The KMSTest.atomic_crtc_disable() method deactivates a CRTC but doesn't
fully disable it, which requires setting the MODE_ID to 0. Furthermore
it doesn't de-associate the CRTC from connectors and planes, which
causes atomic check failures as a fully disabled CRTC can't be
associated with connectors. It can also lead to the next test failing
due to resources still being allocated to the CRTC.
To fix this, introduce an AtomicRequest class that wraps around
pykms.AtomicReq, and stores a copy of all the properties. When the
request is committed the properties are added to a global state, which
is then used to locate and release connectors and planes associated with
the CRTC in KMSTest.atomic_crtc_disable().

The test exercises the CRC API by enabling CRC computation on the
pipeline output, capturing CRC values and verifying that they all match.
