The "Basic code table" in ISO 646 is mostly ASCII, but some code points
either 1) have more than one glyph that can be assigned to them or 2)
have no glyph assigned to them. National versions choose one of the two
glyphs for the code points in group 1) and assign specific glyphs to the
code points in group 2); the International Reference Version assigns the
same glyphs to those code points as does ASCII.
For the "Basic code table" encoding, we map the code points in groups 1)
and 2) to a REPLACEMENT CHARACTER; additional encodings can be added for
the national versions.
Add ENC_ISO_646_IRV (International Reference Version) as an alias for
ENC_ASCII.
Expand some comments, and add some comments, while we're at it.

That way, even if we're not building a protocol tree, so that you don't
get protocol tree items, you can get the display string, e.g. to use in
a column.
Replace the use of the "get display string" routines with calls to those

Add a BASE_SHOW_ASCII_PRINTABLE flag for the "display" field, to use
with FT_BYTES and FT_UINT_BYTES fields; it specifies that, if the field
consists solely of printable ASCII characters, its value be displayed as
a string, in quotes. Have a routine hfinfo_format_bytes() to do that
formatting, depending on the display field value.
Add routines to fetch the display value of string and
FT_BYTES/FT_UINT_BYTES fields; for strings, it's the result of
hfinfo_format_text(), and for byte arrays, it's the result of
hfinfo_format_bytes().
Use BASE_SHOW_ASCII_PRINTABLE for extended attribute data in SMB and
SMB2. Use the routines in question for extended attribute names
(string) and data (bytes). That keeps us from displaying non-text
extended attribute data as if it were text.
Document BASE_SHOW_ASCII_PRINTABLE.

That isn't working, because it depends on the notion that for every
"endpoint type" there's a "port type" for the packet_info structure;
that's not true for ISDN channels.
The whole point of "use the packet_info structure when trying to find a
conversation and create it if it doesn't exist" is to use address
information *already filled in by somebody for use by other dissectors*;
we don't do that with the ISDN channel number, because there's no *need*
to do so.
So just add a new find_or_create_conversation_by_id() routine, which
passes the packet_info structure to get the frame number, and explicitly
passes the endpoint type and ID. Use that in the ISDN dissector.

Compiled plugins are stored in subfolders of the plugin folders, with
the subfolder name being the Wireshark minor version number (X.Y). There is
another hierarchical level for each Wireshark library (libwireshark, libwscodecs
and libwiretap).
The folder names are respectively plugins/X.Y/{epan,codecs,wiretap}.
Currently we only distribute "epan" (libwireshark) plugins.
