A conversation in Wireshark might have two endpoints or might have no
endpoints; few if any have one endpoint. Distinguish between
conversations and endpoints.
These display bases work to replace unprintable characters so the
name is a misnomer. In addition they are the same option and this
display behaviour is not something that is configurable.
This does not affect encodings because all our internal text strings
need to be valid UTF-8 and the source encoding is specified using
ENC_*.
Remove the assertion for valid UTF-8 in proto.c because
tvb_get_*_string() must return a valid UTF-8 string, always, and we
don't need to assert that, it is expensive.
UatModel::insertRows in ui/qt/modles/uat_model.cpp calls the set
callback with an empty string when adding a new row, before the
check callback is called. So the set callback should handle the empty
string and not run off the end if handed invalid entry. Use the same
validation with hex_str_to_bytes in both callbacks so that they agree
about what is valid input.
Prevents a buffer overflow noticed by ASAN.
If we're going to reject a packet because it's not a valid EPL
packet, do so at the beginning, before setting the column values
and changing the port types and values.

The static arrays are supposed to be arrays of const pointers to int,
not arrays of non-const pointers to const int.
Fixing that means some bugs (scribbling on what's *supposed* to be a
const array) will be caught (see packet-ieee80211-radiotap.c for
examples, the first of which inspired this change and the second of
which was discovered while testing compiles with this change), and
removes the need for some annoying casts.
Also make some of those arrays static while we're at it.

Handling of preferences is often done in the dissector handoff
registration. Therefore this function is often registered as
callback while registering preference handling for the module.
In this way the preferences are processed both when registering
the dissector and when changes happen.
Some dissectors opt to register a seperate callback function to
be called when preferences change. Now these have to be called
from the dissector handoff function explicitly, in order to have
the preferences processed during dissector registration.
This becomes explicitly apparent when the port registration comes
into play. With the migration to using dissector registration on
ports with preference this port (range) is often retrieved from
the preferences to match against the ports in a packet to determine
an incoming or outgoing packet of a server. In case the callback
function is not called from the dissector registration this
determination fails, until the preferences are applied/changed,
causing the preference handling callback to be called.
This change add the calling of the callback during dissector
registration, fixing some dissector port registrations in the
process.
