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.

Now that "bytes consumed" can be determined, should tcp_dissect_pdus() take advantage of that?
Should tcp_dissect_pdus return length (bytes consumed)? There are many dissectors that just call tcp_dissect_pdus() then return tvb_length(tvb). Seems like that could all be rolled into one.

While it was an interesting exercise it just doesn't
work good enough to stay, i.e. it doesn't automatically
pick up changes but requires rerunning cmake instead.

The intention is to aid in the removal of pinfo->private_data use as well as static global variables in a dissector. For now, all calls to call_ber_oid_callback have the data parameter set to NULL.

- when the text parameter is constant col_add_str() and col_set_str() are equivalent but col_set_str() is faster.
- same for replace col_append_fstr and col_append_str
- remove col_clear() when it's redundant:
+ before a col_set/col_add if the dissector can't throw an exception.
- replace col_append() after a col_clear() with faster col_add... or col_set

convert all existing UAT update callbacks to use glib memory instead of
ephemeral memory for that string.
UAT code paths are entirely distinct from packet dissection, so using ephemeral
memory was the wrong choice, because there was no guarantees about when it would
be freed.
The move away from emem still needs to be propogated deeper into the UAT code
itself at some point.
Net effect: remove another bunch of emem calls from dissectors, where replacing
with wmem would have caused assertions.

This patch adds modelines and cleans up the irregular indentation of
this dissector's code. The only other change was in
asn1/c1222/packet-c1222-template.c to consolidate an #ifdef that had a
redundant #endif (line 812) and subsequent reopening #ifdef (line
824). The only thing between them was comments, so the span of the
original #ifdef (line 644) was simply extended by eliminating those
two lines.
The purpose for this patch is to make the file easier to edit and
understand in advance of more substantive patches later. This patch
is intended to be easy to review by having only non-substantive
changes.

Fix memory leaks and bad memory accesses in c1222 dissector.
From me: use realloc in a handoff function since it may get called multiple
times, and we only need the latest.
