64c50c0e97 declared support for decomposing
them but omitted to implement it; this adds an implementation.
Also do the same for end-of-stream NAL units, since they are equivalent.

use the hexdump -C SMM0005.rcv get:

There are different the RCV file format for VC-1, vc1test
just handle the case 2 now, this fix will support the case 1.
(Both of test clips come from: SMPTE Recommended Practice -
VC-1 Decoder and Bitstream Conformance). And I think I got
a older VC-1 test clip in the case 1.

Fixes bug with HTTP DELETE when HTTP Persistent is ON.
Right now, HTTP Persistent connections is supported only for POSTs and PUTs.
HTTP DELETE will still open a new connection every time.
Make the function static, or else Clang complains with:
error: no previous prototype for function 'decklink_get_attr_string' [-Werror,-Wmissing-prototypes]

This tries to follow the webrtc code. For example using cliping and 64 bit as in WebRtcSpl_DotProductWithScale()
and not doing so in other places.
I could not find anything in rfc3951 and the reference code inside which would
explain what to do in these corner cases.
