epan/show_exception.c, as it's used outside
epan/dissectors/packet-frame.c. Update their callers to include
<epan/show_exception.h> to get their declaration.
Add a CATCH_NONFATAL_ERRORS macro that catches all exceptions that, if
there's more stuff in the packet to dissect after the dissector call
that threw the exception, doesn't mean you shouldn't go ahead and
dissect that stuff. Use it in all those cases, including ones where
BoundsError was inappropriately being caught (you want those passed up
to the top level, so that the packet is reported as having been cut
short in the capture process).
Add a CATCH_BOUNDS_ERRORS macro that catches all exceptions that
correspond to running past the end of the data for a tvbuff; use it
rather than explicitly catching those exceptions individually, and
rather than just catching all exceptions (the only place that
DissectorError should be caught, for example, is at the top level, so
dissector bugs show up in the protocol tree).
Don't catch and then immediately rethrow exceptions without doing
anything else; just let the exceptions go up to the final catcher.
Use show_exception() to report non-fatal errors, rather than doing it
yourself.
If a dissector is called from Lua, catch all non-fatal errors and use
show_exception() to report them rather than catching only
ReportedBoundsError and adding a proto_malformed item.
Don't catch exceptions when constructing a trailer tvbuff in
packet-ieee8023.c - just construct it after the payload has been
dissected, and let whatever exceptions that throws be handled at the top
level.
Avoid some TRY/CATCH/ENDTRY cases by using checks such as
tvb_bytes_exist() before even looking in the tvbuff.

keys to have _uint in their names, to match the routines that handle
dissector tables with string keys. (Using _port can confuse people into
thinking they're intended solely for use with TCP/UDP/etc. ports when,
in fact, they work better for things such as Ethernet types, where the
binding of particular values to particular protocols are a lot
stronger.)

- Change spaces in the name to underscores before comparing it to the blurb.
- Check if the type simply as T_ prepended to the name.
- Don't put in a blurb of "NULL".

(1) Trailing/leading spaces are removed from 'name's/'blurb's
(2) Duplicate 'blurb's are replaced with NULL
(3) Empty ("") 'blurb's are replaced with NULL
(4) BASE_NONE, NULL, 0x0 are used for 'display', 'strings' and 'bitmask' fields
for FT_NONE, FT_BYTES, FT_IPv4, FT_IPv6, FT_ABSOLUTE_TIME, FT_RELATIVE_TIME,
FT_PROTOCOL, FT_STRING and FT_STRINGZ field types
(5) Only allow non-zero value for 'display' if 'bitmask' is non-zero

dissect_ber_boolean() to return a value and update asn2wrs to generate the new signature.
Regenerate all BER dissectors.

Since the use of the function 'dissect_ber_tagged_type' for DialoguePortion,
the file tcap.cnf must be updated to remove the decoding of the tag and length.
This decoding is now done in the new function 'dissect_ber_tagged_type'.
The file tcap.cnf has been updated to take into account this change.
But this leads to a change in tcap.asn too, for the definition of the
ExternalPDU.
I think this part of the ASN1 file is specific to Wireshark and can be
modified.
In the meantime, I did update the DEBUG part for packet_ber.c for the function
(dissect_ber_tagged_type)

Correct bug in TCAP statistics when read filter is used.
Rename the TCAP decoding functions to show which are ITU vs. ANSI.
Don't unregister an ITU SSN if it's used by an ANSI subdissector.
svn path=/trunk/; revision=22421
- add support of session management for tcap ANSI.
(In fact, this support already exist for ANSI MAP subdissector, but as our
simulators can reuse the tcap transaction Id, the decoding of the response
may be wrong)
- move the code related to asn1 in tcap.cnf, and update tcap.cnf
- move the code related to the session management in tcap-persistentdata
- add a compilation option to free the entry in the hashtable for a closed
transaction. This is used only for tshark statistics generation, with huge file.
- cleanup and add some comments
Add Id tags to epan/tcap-persistentdata.{c,h}
