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.

Cast away some implicit 64-bit-to-32-bit conversion errors due to use of
sizeof.
Cast away some implicit 64-bit-to-32-bit conversion errors due to use of
strtol() and strtoul().
Change some data types to avoid those implicit conversion warnings.
When assigning a constant to a float, make sure the constant isn't a
double, by appending "f" to the constant.
Constify a bunch of variables, parameters, and return values to
eliminate warnings due to strings being given const qualifiers. Cast
away those warnings in some cases where an API we don't control forces
us to do so.
Enable a bunch of additional warnings by default. Note why at least
some of the other warnings aren't enabled.
randpkt.c and text2pcap.c are used to build programs, so they don't need
to be in EXTRA_DIST.
If the user specifies --enable-warnings-as-errors, add -Werror *even if
the user specified --enable-extra-gcc-flags; assume they know what
they're doing and are willing to have the compile fail due to the extra
GCC warnings being treated as errors.

Add a new WTAP_ENCAP_BACNET_MS_TP_WITH_PHDR encapsulation type, for use
by the EyeSDN file reader; unlike the pcap-encapsulated MS/TP, it
includes a direction indicator. Don't treat WTAP_ENCAP_BACNET_MS_TP as
if it has a direction indicator, as it doesn't; instead, do that for
WTAP_ENCAP_BACNET_MS_TP_WITH_PHDR.
Add some missing entries to encap_table_base for WTAP_ENCAP_ values that
didn't get entries added.

or other information; WTAP_ENCAP_MTP2_WITH_PHDR is for MTP2 *with* such
a pseudo-header. Use WTAP_ENCAP_MTP2_WITH_PHDR for the EyeSDN captures,
and don't assume there's a pseudo-header if you have WTAP_ENCAP_MTP2.

by Wiretap, to indicate whether certain fields in that structure
actually have data in them.
Use the "time stamp present" flag to omit showing time stamp information
for packets (and "packets") that don't have time stamps; don't bother
working very hard to "fake" a time stamp for data files.
Use the "interface ID present" flag to omit the interface ID for packets
that don't have an interface ID.
We don't use the "captured length, separate from packet length, present"
flag to omit the captured length; that flag might be present but equal
to the packet length, and if you want to know if a packet was cut short
by a snapshot length, comparing the values would be the way to do that.
More work is needed to have wiretap/pcapng.c properly report the flags,
e.g. reporting no time stamp being present for a Simple Packet Block.

Strictly speaking, it appears that __except(EXCEPTION_EXECUTE_HANDLER)
rather than __exept(TRUE) should be used altho in actuality there's
no difference since TRUE (as defined by GLIB) == EXCEPTION_EXECUTE_HANDLER.

pseudo-header, and hence there's no direction indication. Don't set
pinfo->p2p_dir for it. Use WTAP_ENCAP_BLUETOOTH_H4_WITH_PHDR, not
WTAP_ENCAP_BLUETOOTH_H4, for capture files where we have the direction.
Don't assume pinfo->p2p_dir is either P2P_DIR_SENT or P2P_DIR_RECV when
setting the info column in various Bluetooth dissectors; it might be
unknown.
In the HCI H4 dissector, put the direction into the info column
regardless of whether we have a type match or not; the dissectors for
HCI packet types appear to assume it's been set (as they put a blank at
the beginning of the stuff they append to the direction).

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.)
