[PATCH v2 0/6] MR8527: Draft: mf/tests: Fix some leaks and skip memory-hungry H264 encoder tests on 32bit.

[Rémi Bernon (＠rbernon)]

The test now consistently fails, probably since the docker image update, with x264enc failing to allocate memory. The failure seem to happen only if some tests are run before it, but that seem to come from memory fragmentation rather than leaks. Except for the leaks fixed here, I couldn't find any other through Valgrind or GStreamer leak checkers.

Tests show that some AM_MEDIA_TYPE fields aren't touched, but
MFInitMediaTypeFromAMMediaType may try to access them.
