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.

This saves many dissectors the need to find the data dissector and store a handle to it.
There were also some that were finding it, but not using it.
For others this was the only reason for their handoff function, so it could be eliminated.

Started by grepping call_dissector_with_data, call_dissector_only and call_dissector and traced the handles passed into them to a find_dissector within the dissector. Then replaced find_dissector with find_dissector_add_dependency and added the protocol id from the dissector.
"data" dissector was not considered to be a dependency.

Some LLC OUI dissector tables didn't have an associated protocol, so they were left without one (-1 used)

The target here is the Decode As dialog where protocols have multiple registrations into a dissector table and that shows up as multiple entries in the Decode As dialog list with the same name so users are unsure which "dissector" they are choosing.
The "default" behavior (done in this commit) is to not allow duplicates for a dissector table, whether its part of Decode As or not. It's just ENFORCED for Decode As.

The "LEN" field is the "length of the MAC frame", in bytes; confusingly,
it includes the extended header length, but not the fixed-length part of
the header (including the FCS), so it's not the "length after HCS".
Rename it to "docsis.len", as it's always LEN, not SID; there's a
separate field for the SID.
Rename the Extended Header Length field to docsis.ehdrlen, and the
Number of Concatenated Frames to docsis.concat_cnt, so that different
uses of the "MACPARM" part of the header are flagged differently.
Update some comments while we're at it.

- same for replace col_append_fstr and col_append_str
- remove col_clear() when it's redundant:
+ before a col_set/col_add if the dissector can't throw an exception.
- replace col_append() after a col_clear() with faster col_add... or col_set

CableLab's (http://www.cablelabs.com/) DOCSIS Radio Frequency Interface
(RFI) specification. The latest version of this specification is currently
available at
http://www.cablemodem.com/specifications/specifications20.html . Packet
formats for DCC are defined in sections 8.3.20 (DCC-REQ), 8.3.21
(DCC-RSP), and 8.3.22 (DCC-ACK) of the RFI specifications (referencing
version CM-SP-RFIv2.0-I10-051209). In addition, this patch adds support
for the DCD packet as defined in the DOCSIS Set-Top Gateway (DSG)
Specification. The latest version of this specification is currently
available at http://www.cablemodem.com/specifications/gateway.html . The
format of the DCD packet is defined in section 5.3.1 of the DSG
specification (referencing version CM-SP-DSG-I06-051209).
