src: new error reporting approach for XML/JSON parsers

I have added a new structure for reporting some errors in parser
that we can't cover with errno.

In this patch, we have three errors that we can't cover with errno:

NFT_PARSE_EBADINPUT : Bad XML/JSON format in the input
NFT_PARSE_EMISSINGNODE : Missing node in our input
NFT_PARSE_EBADTYPE : Wrong type value in a node
