Call "dissect_attribute_value_pairs()" regardless of whether we're
building a protocol tree, so the EAP subdissector is always called.
"dissect_attribute_value_pairs()" is only called when the length of AVPs
in the packet is non-zero; don't bother checking for a zero length.
Don't put two items in for each AVP - one is sufficient.
Add some more length checks when processing AVPs. Don't require AVPs to
be at least 3 bytes long - they might have just a type and length; let
an exception be thrown if that's a problem.
Don't require that the entire AVP be available in the tvbuff before
processing it; let an exception be thrown as we're processing the AVP if
we don't have all the data, so the stuff before the end is processed.
Give the tvbuff for the AVP data a length that reflects the length of
data left in the tvbuff, so that the appropriate exception is thrown if
the packet was cut short by a snapshot length.
Don't have a fixed-length buffer for reassembled EAP messages; grow it
as necessary.
Don't special-case the initial part of the processing of EAP messages;
put in the standard length item, as well as, for fragments, an item for
the fragment data.
Check for non-consecutive EAP-Message attributes.
Set the columns non-writable while dissecting the EAP message, so
Protocol and Info reflect the RADIUS packet.
Doing the reassembly by gluing together all the consecutive EAP-Message
attributes means we don't need help from the EAP dissector, returning
the total length of the EAP message. Get rid of the no-longer-needed
eap_fragment dissector; just call the regular EAP dissector.

(presumably-)harmless-but-otherwise-unremovable const-to-nonconst
warnings.
In the TACACS dissector, clean up the variables used in option parsing
to avoid some const-to-nonconst warnings.
Clean up some white space.

- use ep_alloc for reassemling eap fragments instead of a static buffer
- use ep_strdup_printf() instead of a static buffe to return the cosine's VP/VC AVP label
- add few TODO comments

read the RADIUS directory.
The error string from "radius_load_dictionary()" is g_malloced; free it,
and g_strdup the "Could not find the radius directory" error, so we
don't have to worry about constant vs. g_malloced strings.

add a "match_strval_idx()" routine that does the same thing, and have
"match_strval()" call it.
Make those routines, and "val_to_str()", return a "const" pointer.
Update dissectors as necessary to squelch compiler warnings produced by
that.
Use "val_to_str()" rather than using "match_strval()" and then, if the
result is null, substituting a specific string. Clean up some other
"match_strval()"/"val_to_str()" usages.
Add a null pointer check in the NDPS dissector's "attribute_value()"
routine, as it's not clear that "global_attribute_name" won't be null at
that point.
Make some global variables in the AFS4INT dissector local.
Make some routines not used outside the module they're in static.
Make some tables "static const".
Clean up white space.
Fix Gerald's address in some files.

in a simple approach, I've replaced all g_assert() and g_assert_not_reached() calls by their exception throwing counterparts DISSECTOR_ASSERT() and DISSECTOR_ASSERT_NOT_REACHED()
this will replace application crash by showing a dissector bug, which is the desired behaviour
there were some g_assert calls in the protocol registering functions, which might not be acting as expected now, but to be able to simply search for g_assert in the future I've replaced that calls too
one g_assert remained, the one when someone throws an unknown exception "into" packet_frame.c, but IMHO this one should remain.

least 3 - 2 for type+length and 1 for the tag - so treat a "tagged
string" field as bad if there isn't at least one byte of data. (It's a
bit odd that the RFC says that the tag must be in the range 0x01-0x1F -
that sounds suspiciously as if they're saying "printable characters
aren't valid tags", to allow untagged strings, which might suggest that
a field with a length of 2 should be interpreted as an empty string.)

we're fetching from the AVP.
In the case of a tagged string, if the length is 2 (meaning the data
length is 0), assume there's no tag.

for organizations to an <epan/sminmpec.h> header, and add in the ones
that were used (without #defines) in the Diameter dissector.
Merge the value_string tables for them from the Diameter and Radius

Use that value_string table in the Diameter and Radius dissectors.
Constify some stuff in the Diameter dissector.
