This patch adds reassembly_table_destroy calls as cleanup function for dissectors which have a simple init routine that just calls reassembly_table_init (comments are ignored). The changes were automatically generated using https://git.lekensteyn.nl/peter/wireshark-notes/diff/one-off/cleanup-rewrite.py?id=4cc0aec05dc67a51926a045e1955b7a956757b5e (with the if and assignment parsers disabled). The only difference from the autogenerated output is that the XXX comments from the init routines in smb-pipe and tds dissectors are kept.
