Guy Harris ce3d2ff3de Rename dissector_add_handle() to dissector_add_for_decode_as().
Hopefully that name makes it clear what the routiner's purpose is, and
will encourage people to use it rather than using dissector_add_uint()
with a bogus integer value.

Guy Harris 21a1208735 Introduce 802.11 dissectors with wired-in "FCS present" indications.
For a number of protocols that encapsulate 802.11 frames inside packets,
whether the frame includes an FCS or not is specified by the protocol,
not by whether the link-layer frame carrying the packets *itself*
includes an FCS.  As we've done with Ethernet, add "_withfcs" and
"_withoutfcs" dissectors, which *don't* check the pseudo-header FCS
length indication, and call those, rather than dissectors that check the
pseudo-header length indication, from the dissectors for those protocols.

Guy Harris 6b629c4d92 Move show_exception() and show_reported_bounds_error() to
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.

Chris Maynard fb19d6ab0f Since the call to proto_tree_add_text() was #if 0'd out, there's no need to assign the return value of tvb_new_subset to wlan_tvb. Actually, there's probably no need to call tvb_new_subset() in the first place, but for now let's just tackle the unused value warning and leave the FIXME for someone who knows more about this. Fixes Coverity CID 864.

Guy Harris a8bc4a0d13 Rename the routines that handle dissector tables with unsigned integer
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.)
