When a new Field is created, does as following:
* Check whether that field is registered, by using `proto_registrar_get_byname`. This is current behavior.
* (patched) If not registered, check whether that field is defined in LUA and will be registered. This is performed in `wslua_is_field_available` accessing LUA context.
* If not, an error "a field with this name must exist" occurs.

Lua cannot store a 64 bit integer with full precision, which is used

is supported before trying to open for writing - the attempt to open for
writing will do the check for you. Instead, check for specific errors
if the attempt to open for writing fails, and use somewhat more specific
error messages for certain error codes. (We should perhaps check for
even more error codes in those cases.)
That gets rid of all external calls to wtap_dump_can_write_encap(), so
remove it from wtap.h and make it static.

Iterate backwards through the linked list of identically-named fields in the lua
bindings since the list is, in fact, created backwards by
proto_register_field_init(). There is some question about whether that is
actually intended, but the rest of the code seems to assume it's normal so we
will too. It was possibly a performance consideration, though that's not
well-documented if so.
Either way, this is the simplest and safest method of fixing the issue with the
lua bindings. See the bug for more analysis.

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.

Fix the Lua tostring() method on FieldInfo objects such that it always returns
a string, although the string might be '(unknown)', '(none)', or '(n/a)'. This
is more conformant to Lua's API style.
Also create a new 'FieldInfo.display' accessor table member, which Lua
scripts can use instead of tostring() to get what the GUI displays.
From me:
Misc indentation fixes, remove redundant 'return' statement.

Cast away some implicit 64-bit-to-32-bit conversion errors due to use of

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.

This works between C and Lua.
In C the pinfo.private_table pointer must be initialized using
g_hash_table_new (g_str_hash, g_str_equal);
In Lua the values are available using pinfo.private.<key>, and the
table is created automatically on first usage. It's possible to use
this datatypes: nil, boolean, number and string, but every value
is converted to string so numbers must be converted using tonumber()
on usage. Boolean is either nil or an empty string.

Find the respective menu items under 'Statistics->BACnet'.
Packets can be sorted by different criteria:
- Src/Dst IP adresses

- Service
From me:

- Name variables for tick_stat_node() don't need to be static.
- Change updateBacnetInfoValue() to require 'data' to be ep_ allocated. Change
the couple of calls that did not send in ep_ allocated data to do so.
- Change one or two functions to be static.
- Do not use (memory-unsafe) g_sprintf().
- Use ep_strconcat() instead of leaking memory with g_strconcat().
- Put back one if(tree) that doesn't appear to do any harm.
- Remove variable declarations and #includes from the header file.

c. CVARSDLL definitions (not usage) have been removed from the various makefiles.

-DWIN32 and -DNULL=0 do not appear to be needed (any more);
-D_MT and _D_DLL are not needed since /MP causes these definitions.
