Similar to the "tcp.port" changes in I99604f95d426ad345f4b494598d94178b886eb67,
convert dissectors that use "udp.port".
More cleanup done on dissectors that use both TCP and UDP dissector
tables, so that less preference callbacks exist.

This patch introduces new APIs to allow dissectors to have a preference for
a (TCP) port, but the underlying data is actually part of Decode As functionality.
For now the APIs are intentionally separate from the regular APIs that register a
dissector within a dissector table. It may be possible to eventually combine the
two so that all dissectors that register with a dissector table have an opportunity
to "automatically" have a preference to adjust the "table value" through the
preferences dialog.
The tcp.port dissector table was used as the guinea pig. This will eventually be
expanded to other dissector tables as well (most notably UDP ports). Some
dissectors that "shared" a TCP/UDP port preference were also converted. It also
removed the need for some preference callback functions (mostly when the callback
function was the proto_reg_handoff function) so there is cleanup around that.
Dissectors that has a port preference whose default was 0 were switched to using
the dissector_add_for_decode_as_with_preference API rather than dissector_add_uint_with_preference
Also added comments for TCP ports used that aren't IANA registered.

Have all dissector tables have a "supports Decode As" flag, which
defaults to FALSE, and which is set to TRUE if a register_decode_as()
refers to it.
When adding a dissector to a dissector table with a given key, only add
it for Decode As if the dissector table supports it.
For non-FT_STRING dissector tables, always check for multiple entries
for the same protocol with different dissectors, and report an error if
we found them.
This means there's no need for the creator of a dissector table to
specify whether duplicates of that sort should be allowed - we always do
the check when registering something for "Decode As" (in a non-FT_STRING
dissector table), and just don't bother registering anything for "Decode
As" if the dissector table doesn't support "Decode As", so there's no
check done for those dissector tables.

If an ASN.1 dissector is calling register_dissector for itself in its proto_register_xxx
function and then calling find_dissector for itself in its proto_reg_handoff_xxx
function then just create a static handle for that dissector and use the return
value of register_dissector, so the find isn't necessary.

The target here is the Decode As dialog where protocols have multiple registrations into a dissector table and that shows up as multiple entries in the Decode As dialog list with the same name so users are unsure which "dissector" they are choosing.
The "default" behavior (done in this commit) is to not allow duplicates for a dissector table, whether its part of Decode As or not. It's just ENFORCED for Decode As.

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.

For details see comments in Bug 9920.
The executive summary:
Bug 9920 is a crash caused by a couple of issues:
1) The memory ownership model for the rtp_dyn_payload hashtable is split: SDP
creates the rtp_dyn_payload hashtable, but RTP can free it. Since there isn't
*one* pointer to the hashtable, RTP freeing it means SDP has a dangling
pointer.
2) Either the SDP dissector shouldn't be creating two separate, unique
hashtables for multiple media channels of the same addr:port, or RTP shouldn't
be free'ing the previous one.
