sequence-layer is serialized in little-endian byte order except for
STRUCT_C which is serialized in big-endian byte order.
But since STRUCT_A and STRUCT_B fields are defined as unsigned int msb
first, we have to pass them as big-endian to their parsing function. So
we basically use temporary buffers to convert them in big-endian.
See SMPTE 421M Annex J and L.

If we don't have a seq_layer_buffer, we also don't have a valid
seq_layer because there are set together in
gst_vc1_parse_handle_seq_layer().
So when output header format is sequence-layer and when we don't have a
seq_layer_buffer, we forge one from seq_hdr.

Sequence-layer and frame-layer are serialized in little-endian byte
order except for STRUCT_C and framedata fields as described in SMPTE 421M Annex
L.

packetized mode is being set when framerate is being set
which is not correct. Changing the same by checking the
input segement format. If input segment is in TIME it is
Packetized, and if it is in BYTES it is not.

Previously we only refetched the playlist if downloading a fragment
has failed once. We should also do that if it failed a second or third time,
chances are that the playlist was updated now and contains new URIs.
This commit fix several issues with sequence layer header forging on
update_caps():
- 0x00000004 unsigned integer is before STRUCT_C.
- Set reserved bits of STRUCT_C to their values for simple/main
profiles in sequence layer header format and ASF header format.
- Sequence layer shall be represented as a sequence of 32 bits unsigned
integers and shall be serialized in little-endian byte order except
for STRUCT_C which shall be serialized in big-endian byte-order.
See SMPTE 421M Annex L for more details about sequence layer format.

packet_length is defined as a guint16 in the PESHeader structure. This
definition match the specification. But since we add 6 bytes to the
packet_length value (length of start_code + stream_id + packet_length),
we can overflow the guint16 when the value in the PES header is greater
than 65529.
So use a guint32 instead of a guint16 to avoid overflow.
