5f24fe82e5 mpegvideo: Initialize chroma_*_shift and codec_tag even if the size is 0
This fixes breakage in a few fate tests on certain setups
(that for some reason didn't break on OS X) after the previous
commit (8812a8057). Currently, some video streams are initialized
in ff_MPV_common_init with width/height set at 0 and only changed
to a proper video size with ff_MPV_common_frame_size_change later.

The breakage was diagnosed by Anton Khirnov.

And fix the AMF_DATA_TYPE_ARRAY parsing while at it.

A MIXEDARRAY type, as the ARRAY, store the number of elements in
an uint32 before the list. The ARRAY is strict and does not have
an OBJECT terminator, MIXEDARRAY behaves like an OBJECT type and
a different than stated number of element can be present.

the use of the non-secure versions of several functions.  Defining
_CRT_SECURE_NO_WARNINGS silences these warnings.
