Have all dissector tables have a "supports Decode As" flag, which
defaults to FALSE, and which is set to TRUE if a register_decode_as()
refers to it.
When adding a dissector to a dissector table with a given key, only add
it for Decode As if the dissector table supports it.
For non-FT_STRING dissector tables, always check for multiple entries
for the same protocol with different dissectors, and report an error if
we found them.
This means there's no need for the creator of a dissector table to
specify whether duplicates of that sort should be allowed - we always do
the check when registering something for "Decode As" (in a non-FT_STRING
dissector table), and just don't bother registering anything for "Decode
As" if the dissector table doesn't support "Decode As", so there's no
check done for those dissector tables.

We may want to add expert infos for IPv6 extension headers over IPv4 (TODO).
Any side-effects that don't make sense (e.g: IPv6 Routing over IPv4) are
ignored.
The IPv6 Next Header decode as is replaced by IP Proto decode as. It
didn't fit a conceptual model well and it also was not working very well
in practice (for multiple extension headers).
We now support decoding any IP Protocol number as an extension header.

To quote RFC 4960:
Chunk Length: 16 bits (unsigned integer)
This value represents the size of the chunk in bytes, including
the Chunk Type, Chunk Flags, Chunk Length, and Chunk Value fields.
Therefore, if the Chunk Value field is zero-length, the Length
field will be set to 4. *The Chunk Length field does not count any
chunk padding.*
Chunks (including Type, Length, and Value fields) are padded out
by the sender with all zero bytes to be a multiple of 4 bytes
long. This padding MUST NOT be more than 3 bytes in total. The
Chunk Length value does not include terminating padding of the
chunk. However, it does include padding of any variable-length
parameter except the last parameter in the chunk. The receiver
MUST ignore the padding.
Note: A robust implementation should accept the chunk whether or
not the final padding has been included in the Chunk Length.
so the the chunk is *not* required to include the length of the final
padding in the chunk, although any padding *between* variable-length
parameters in the chunk must be included in the length (obviously, as
it's part of the chunk data).
