    pcap-common: Account for padding in ENCAP_ERF len and caplen
    
    Set len and caplen in pcap_read_post_process to actual wlen/payload length like for native ERF.
    This fixes padding incorrectly showing as an Ethernet trailer or equivalent as
    well as packet length calculations being incorrect.
    
    Fix up rlen when writing ENCAP_ERF so it isn't longer than the actual record
    length. This differs from native ERF behaviour which pads the record instead
    but there is currently no non-hackish way to do this for pcap/pcap-ng.
    
    Note: This means records captured from a DAG card in Wireshark (or old
    PCAP(-NG) files opened) will have padding stripped when saved as PCAP(-NG) and
    thus cannot be transmitted when converted to native ERF without aligning first.
    However, if the file is saved as native ERF originally the padding will be
    preserved (and zeroed). Given that extension header write support was very
    broken and transmission of PCAP(-NG) is not supported without conversion this
    is not expected to have been common.
