ziomon/ziorep_cfgreader: extract PCHID from .config file

Browse Source 
Add an ability for ziorep_config tool to extract PCHID additional adapter
parameter from .config file. With this patch device_info structure will have
pchid field, which can be used by different printers classes. Also add
function for querying PCHID by using of devno for providing reports. Translate
"n/a" field from .config file record into invalid PCHID number.
