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()
(called from ff_h264_build_ref_list(), called from h264_slice_init()).
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.
