We can handle HTTP/1.0 server responses to HTTP/1.1 client requests.

According to 7.4.1.2.3, SPS extension must only follow
sps and can't be picture start then.

The HTTP module will redirect to MMS(H) when applicable, so handing
of the "http" scheem in the MMS module is no longer necessary.

Removing it saves a pointless connection attempt when HTTP fails for a
reason other than redirecting to MMS.

There is no support for TLS in the current MMS plug-in.

Building VLC with a libbluray version older than 0.8.1 results in a build
failure because the BD_EVENT_UO_MASK_CHANGED enum does not exist in those
older versions. This problem manifests itself in Ubuntu 14.04.

This copes with: var a=...,b=...;

If present - this is currently only supported by the playlist.

Header field folding is not implemented.

There is no need for a full URL structure here, and it is sometimes
inconvenient to require one.

Packetized input always contains 1 single NAL.
block_Alloc reserves 32 bytes for header, which
can be used for AnnexB.

In that case it removes almost all allocs+memcpy
towards AnnexB conversion, except N-1 extradata NAL

In all cases avoid memcpy/alloc for trailing NAL.

This avoids loading all Root CAs if we do not actually use them.
