    epson2: Rewrite network I/O

    This addresses GHSL-2020-075 as well as all other problematic code
    uncovered as a result of investigating that.  This includes:

    - buffer overflows due to use of unchecked lengths
    - integer overflows due to type conversions
    - potential memory leaks
    - checking for memory allocation failures

    magicolor: Added security mediation to device discovery

    Extraction of values from the SNMP response were not checked.
    Also fixed a bug that mistakenly matched any SNMP OIDs with the
    first model in the model list, in function mc_get_device_from_identification().

    magicolor: Added security remediation for pixels_per_line.

    This implements a security issue reported by GitHub Security Lab.
    The details are disclosed in GitLab issue #279.
    The issue relates to an invalid scan parameter block being sent to
    the backend containing 8 bytes of 0x00 which leads to pixels_per_line
    being set to 0. Later arithmetic involves the division by this value
    which causes a div by zero crash.
