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.

In most cases... actually in all cases that I know of, the TCP
connection underneath the TLS session is closed at the same time.

User-Agent and CRLF were invalid. Also use standard capitalization.
