This emphasizes that there is no such thing as *the* routine to
construct a subset tvbuff; you need to choose one of
tvb_new_subset_remaining() (if you want a new tvbuff that contains
everything past a certain point in an existing tvbuff),
tvb_new_subset_length() (if you want a subset that contains everything
past a certain point, for some number of bytes, in an existing tvbuff),
and tvb_new_subset_length_caplen() (for all other cases).
Many of the calls to tvb_new_subset_length_caplen() should really be
calling one of the other routines; that's the next step. (This also
makes it easier to find the calls that need fixing.)

This patch introduces new APIs to allow dissectors to have a preference for
a (TCP) port, but the underlying data is actually part of Decode As functionality.
For now the APIs are intentionally separate from the regular APIs that register a
dissector within a dissector table. It may be possible to eventually combine the
two so that all dissectors that register with a dissector table have an opportunity
to "automatically" have a preference to adjust the "table value" through the
preferences dialog.
The tcp.port dissector table was used as the guinea pig. This will eventually be
expanded to other dissector tables as well (most notably UDP ports). Some
dissectors that "shared" a TCP/UDP port preference were also converted. It also
removed the need for some preference callback functions (mostly when the callback
function was the proto_reg_handoff function) so there is cleanup around that.
Dissectors that has a port preference whose default was 0 were switched to using
the dissector_add_for_decode_as_with_preference API rather than dissector_add_uint_with_preference
Also added comments for TCP ports used that aren't IANA registered.

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.
