Peter Wu 3243b6f964 asn1: split off cleanup routines
General approach:

 1. Split allocation (e.g. g_hash_table_new) from deallocation
    (g_hash_table_destroy) into functions named "init" and "cleanup".
 2. Remove guards that test whether the hash tables are set as
    init is always called before cleanup.
 3. Remove setting hash tables to NULL after destruction.
 4. Copy register_init_routine function call and change init to cleanup.
 5. Add cleanup function that calls reassembly_table_destroy if there
    is a reassembly_table_init function.

Some templates were modified as follows:

 - snmp: split renew into init+cleanup, but keep renew for the uat_new
   callback.
 - ldap,ros: Rename init to cleanup as there was no initialization.
 - camel: remove init function from header, make it static. Remove debug
   print.
 - tcap: remove unused ssn_range assignment.

Files in epan/ were regenerated using cmake && make asn1

Michael Mann cd02af56a1 Eliminate (almost all) proto_tree_add_text calls from ASN.1 dissectors.
This mostly involved adding expert info capabilities to many of the dissectors so that they could correctly flag error conditions.

Only remaining proto_tree_add_text calls are in H248.cnf, which has a convoluted way of using hf_ data to make its tree.

Add some files to EXTRA_DIST lists.

Move some .asn files to EXTRA_DIST; they don't need to be in SRC_FILES,
as SRC_FILES always includes EXTRA_DIST, and they *do* need to be in
EXTRA_DIST so that they're in the distribution.

Michael Mann 9b7fb8a811 Create the ability to have packet scoped "proto" data. Bug 9470 (https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=9470)
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.

Guy Harris a2414d8909 Don't wire into the reassembly code the notion that reassemblies should
be done on flows from one address to another; reassembly for protocols
running atop TCP should be done on flows from one TCP endpoint to
another.

We do this by:

	adding "reassembly table" as a data structure;

	associating hash tables for both in-progress reassemblies and
	completed reassemblies with that data structure (currently, not
	all reassemblies use the latter; they might keep completed
	reassemblies in the first table);

	having functions to create and destroy keys in that table;

	offering standard routines for doing address-based and
	address-and-port-based flow processing, so that dissectors not
	needing their own specialized flow processing can just use them.

This fixes some mis-reassemblies of NIS YPSERV YPALL responses (where
the second YPALL response is processed as if it were a continuation of
a previous response between different endpoints, even though said
response is already reassembled), and also allows the DCE RPC-specific
stuff to be moved out of epan/reassembly.c into the DCE RPC dissector.

Jeff Morriss cf012d27b1 Build the ASN.1 dissectors directly into epan/dissectors (rather than building
them and then copying them over).  The "all" target to builds these dissectors
now (instead of "generate_files" and/or "copy_files").

asn2wrs's "-O" option now means "the dissector goes in this directory" (rather
than "all output goes in this directory"); it also means that the "-s" (single
output file) option is now required.

Fix things up so that it's possible to build all of the ASN.1 dissectors in
one shot.

Fix building of conformance files when doing out-of-source-tree builds.


Unfortunately "make all" in the asn1 directory always builds something--I think
because of circular depedencies.
