Effective permitted-alphabet constraints are only PER-visible for
the known-multiplier character string types (X.691 27.1). When
PER-visible, the upper bound of any code point used in the
alphabet needs to be calculated, in particular for the ALIGNED
variant, because that determines whether or not canonical order
is used (X.691 27.5.2, 27.5.4).
Note that even with the change to asn2wrs.py none of the generated
dissectors change, because we don't have any example of ASN.1
with non-PER visible permitted alphabet constraints because of
using them on non known-multiplier character string types
(like UTF8String).
There's some various edge cases that we still don't handle, but
nothing that any of the ASN.1 modules in the repository use.
(Permitted-alphabet constraints using characters outside the
ASCII range, possibly with "CharacterStringList", "Quadruple",
or "Tuple" notation, permitted-alphabet constraints that are
extensible and thus not PER-visible, etc.)
Also fix a fencepost error with the length of the octets to highlight.
Fix#18468
Since we now support ISO 8601 Basic format, have asn2wrs.py
convert GeneralizedTime fields in BER to FT_ABSOLUTE_TIMEs and use
the new common code to convert them. This means that the fields
can be compared with other time fields in filters, etc.
Add tname as argument to Type eth_type_default_body() to fix a warning.
Call to method Type.eth_type_default_body with too many arguments;
should be no more than 1.
Fix some issues discovered by common python linters including:
* switch `None` comparisons to use `is` rather than `==`. Identity !=
equality, and I've spent 40+ hours before tracking down a subtle bug
caused by exactly this issue. Note that this may introduce a problem if
one of the scripts is depending on this behavior, in which case the
comparison should be changed to `True`/`False` rather than `None`.
* Use `except Exception:` as bare `except:` statements have been
discouraged for years. Ideally for some of these we'd examine if there
were specific exceptions that should be caught, but for now I simply
caught all. Again, this could introduce very subtle behavioral changes
under Python 2, but IIUC, that was all fixed in Python 3, so safe to
move to `except Exception:`.
* Use more idiomatic `if not x in y`--> `if x not in y`
* Use more idiomatic 2 blank lines. I only did this at the beginning,
until I realized how overwhelming this was going to be to apply, then I
stopped.
* Add a TODO where an undefined function name is called, so will fail
whenever that code is run.
* Add more idiomatic spacing around `:`. This is also only partially
cleaned up, as I gave up when I saw how `asn2wrs.py` was clearly
infatuated with the construct.
* Various other small cleanups, removed some trailing whitespace and
improper indentation that wasn't a multiple of 4, etc.
There is still _much_ to do, but I haven't been heavily involved with
this project before, so thought this was a sufficient amount to put up
and see what the feedback is.
Linters that I have enabled which highlighted some of these issues
include:
* `pylint`
* `flake8`
* `pycodestyle`
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.
Update documentation and dissector-generator tools.

Because:
- the 2-digit year can only be in the range 1950..2049 according to
https://tools.ietf.org/html/rfc5280#section-4.1.2.5.1
- to avoid confusion, interpreting the year/month/day in a different order may
still represent a valid date.
- now both utcTime and GeneralizedTime are displayed in exactly the same way.
- some tools, like Perl, apply a different date range when converting 2-digit years.
In packet-ber.c two parameters are added to the function dissect_ber_UTCTime:
datestrptr: if not NULL return datetime string instead of adding to tree
or NULL when packet is malformed
tvblen: if not NULL return consumed packet bytes
Also the memory allocation for outstr is now done using the recommended method
as described in the README.developer document.
The calling function in x509af/x509sat uses this to prepend the century.

In some cases (e.g. when a field has a user defined dissection function)
the type reported for this field is a 'virtual' one and the latter is not
contained in selt.type. Consequently, BASE_VAL64_STRING is not set.
Function eth_get_type_attr should return all the attributes of a type and
it seems resonable to expect it to return the BASE_VAL64_STRING. This
will solve the above mentioned error and may solve any possible issue in
other parts that call this function.
