framesync2 will be the base for the version using activate.
Most of the logic will be the same, but the code cannot be shared.
Copying the file initially without change will make the diff
easier to read.
This reverts commit 04aa09c4bc
and reintroduces 0ff5567a30 that
was temporarily reverted due to minor regressions.
It also reverts e5bce8b4ce that fixed FATE refs.
The fate-ffm change is caused by field_order now being set
on the output format because the first frame arrives earlier.
The fate-mxf change is assumed to be the same.

This only enables dlls that are packaged with the application to be
loaded. Due to the limitations of WinRT/UWP it is not allowed to load
external/system dlls so this cannot be used as a complete replacement
for normal win32 dll loading.

default_ref[] is unconditionally initialized in h264_initialise_ref_list()

This fixes the following tsan warning when running fate-h264:

Avoid undefined behavior in skip_input() by checking that enough data is
available before incrementing input pointer.
Check return values of parse_key() and skip_input() and exit early with
error if there is not enough data.
