Most of the time, the return value tells us nothing useful, as we've
already decided that we're perfectly willing to live with string
truncation. Hopefully this keeps Coverity from whining that those
routines could return an error code (NARRATOR: They don't) and thus that
we're ignoring the possibility of failure (as indicated, we've already
decided that we can live with string truncation, so truncation is *NOT*
a failure).
Running `ninja asn1` (or `ninja generate_dissector-t38`) resulted
in loss of some code. It turns out that the autogenerated file was
modified directly instead of the source.

Make the time stamp precision a 4-bit bitfield, so, when combined with
the other bitfields, we have 32 bits. That means we put the flags at
the same structure level as the time stamp precision, so they can be
combined; that gets rid of an extra "flags." for references to the flags.
Put the two pointers next to each other, and after a multiple of 8 bytes
worth of other fields, so that there's no padding before or between them.
It's still not down to 64 bytes, which is the next lower power of 2, so
there's more work to do.

For the moment this mirrors the port_type enumeration (PT_XXX), but the
intent is to move away from using "port types", eliminating most (if not
all)
Added conversation_pt_to_endpoint_type() so that conversations deal with the
correct enumeration. This is for dissector that use pinfo->ptype as input
to conversation APIs. Explicit use of port types are converted to using
ENDPOINT_XXX type.

The intention is to make it more transparent when making a switch
to an "endpoint" over address/port combination.

Register all reassembly tables with a central unit, allowing the
central unit to have the callback that initializes and destroys
the reassembly tables, rather than have dissectors do it individually.

In change 9bcac48403, "t30.hdlc" was
inadvertently changed to "t30.hdlc""rtp"; this meant that we didn't
actually find the T.30 dissector, as we were looking for it under the
name "t30.hdlcrtp".

This got lost as part of change 9132706b2d
- that removed the explicit registering, with a port number, in the
tcp.port and udp.port dissector tables, *without* replacing it with a
dissector_add_for_decode_as() registering it *without* a port number.

Similar to the "tcp.port" changes in I99604f95d426ad345f4b494598d94178b886eb67,
convert dissectors that use "udp.port".
More cleanup done on dissectors that use both TCP and UDP dissector
tables, so that less preference callbacks exist.

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.

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.
