I'm not sold on the name or module the proto_data functions live in, but I believe the function arguments are solid and gives us the most flexibility for the future. And search/replace of a function name is easy enough to do.
The big driving force for getting this in sooner rather than later is the saved memory on ethernet packets (and IP packets soon), that used to have file_scope() proto data when all it needed was packet_scope() data (technically packet_info->pool scoped), strictly for Decode As.
All dissectors that use p_add_proto_data() only for Decode As functionality have been converted to using packet_scope(). All other dissectors were converted to using file_scope() which was the original scope for "proto" data.

was done using textual search+replace, not anything syntax-aware, so presumably
it got most comments as well (except where there were typos).
Use a consistent coding style, and make proper use of the WS_DLL_* defines.
Group the functions appropriately in the header.
I ended up getting rid of most of the explanatory comments since many of them
duplicated what was in the value_string.c file (and were out of sync with the
recent updates I made to those in r48633). Presumably most of the comments
should be in the .h file not the .c file, but there's enough churn ahead that
it's not worth fixing yet.

This is a portion of the patch supplied in bug 7902 (https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=7902). Breaking the functionality up into smaller chunks.
This definitively breaks the Modbus dissection into 3 dissectors:
Modbus - real protocol PDU
Modbus/TCP - Encapsulation of Modbus over TCP (with a small header before PDU)
Modbus RTU - Originally an encapsulation of Modbus over serial (with smaller header + CRC), but can also be sent over TCP.
General cleanup/refactoring (including display filter names) based on the 3 dissectors.
Also included:
1. Enhanced dissection to include preferences for register data to be dissected as UINT16, UINT32 or FLOAT
2. Dynamic port registration
3. Additional fields now filterable

Also (for a few files):
- create/use some extended value strings;
- remove unneeded #include files;
- remove unneeded variable initialization;
- re-order fcns slightly so prefs_reg_handoff...() at end, etc

The attached patches fix the following issues:
1. CIP-Motion shouldn't be a heuristic dissector. CIP-Motion packets are
determined by specific fields in a CIP ForwardOpen. I ran into situations
where CIP-Motion's "vague" heuristics incorrectly dissected packets meant for
CIP-Safety. Of course this requires the ForwardOpen to be in the trace, but it
is the most deterministic way to have CIP-Motion packets.
2. Minor bugfix to the CIP-Safety dissector. A couple of fields were
"missing", causing errant malformed packets.

Modbus object support for CIP dissector
Support for the Modbus object within the CIP dissector. Essentially wraps the Modbus protocol within a CIP object.
Also included update to Modbus error code per

Don't set mr_mult_req_info->num_services until we're sure we've
initialized the full structure for that service. Otherwise if we
happen to throw an exception before initializing the whole
structure, we'll core someplace (like dissect_cip_generic_service_rsp())
which expects all num_services entries to be fully initialized.
