wiretap: fix leak of options_buf and document memory handling
Manually checked all callers of wtap_seek_read to ensure that
wtap_rec_cleanup is called. Added missing wtap_rec_cleanup to:
- Completion of sequential read: wtap_sequential_close
- Callers of wtap_seek_read:
- users of cf_read_record_r:
- PacketListRecord::dissect
This fixes one of the two ASAN memleak reports while running
test_tshark_z_expert_comment and test_text2pcap_sip_pcapng (the other is
about opt_comment which is still unfixed).
Vasil Velichkov also found this issue and came up with a similar fix.
