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
