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.
Part 1/2 as the commits were too big for CI.
Largely find/replace, with a few manual tweaks. Then regenerate the asn1
dissector sources and make sure everything still builds. There are a
handful of cases I skipped as too complex, but this covers most of the
asn1 dissectors.
The LAC, RAC, SAC, and TAC tend to be defined in ASN.1 as OCTET STRINGS
of lengths 1, 2, or 3. It generally makes sense to dissect them as
FT_UINT[8,16,24], as appropriate, with BASE_DEC_HEX instead of as FT_BYTES,
so standardize on that. See commit d6f91a7ca4
for similar work for S1AP.
Use the new stat_tap_find_table function during init to check if our
statistics table already exists.
If so, we can safely assume that its rows have already beend initialized.
All we have to do is clear the data that was collected by the tap.
Done by scanning the asan1 template files. If there are spelling
mistakes in the specifications, we should ignore. Note that for z3950, I had
already found and accidentally fixed the same errors in the generated
file (before I taught my script to ignore gnerated dissector files).
'check_tfs.py --common' can look for tfs values that appear multiple times.
Current output prior to these dssector changes was:

('User', 'Provider') appears 3 times in: ['epan/dissectors/packet-q2931.c', 'epan/dissectors/packet-q931.c', 'epan/dissectors/packet-q933.c']
The first and last ones were made common, the others seem a little too specialised.
Checking some of the existing items in tfs.c (using QtCreator's 'Find Usages'),
some of the common items are used a lot, but many of them are not referenced.

This allows taps that can fail to report an error and fail; a failed
tap's packet routine won't be called again, so they don't have to keep
track of whether they've failed themselves.
We make the return value from the packet routine an enum.
Don't have a separate type for the per-packet routine for "follow" taps;
they're expected to act like tap packet routines, so just use the type
for tap packet routines.
One tap packet routine returned -1; that's not a valid return value, and
wasn't one before this change (the return value was a boolean), so
presume the intent was "don't redraw".
Another tap routine's early return, without doing any work, returned
TRUE; this is presumably an error (no work done, no need to redraw), so
presumably it should be "don't redraw".
Clean up some white space while we're at it.

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.
