examples: XML parsing examples

Some code snipplets to add tables/chain/rules using the XML representation.

The examples contains:
 * A binary to parse/add the object using libnftables.
 * A shellscript to easily call that binary, doing some tests.
 * table/chain/rule sample XML file.

I included my name in new files, but I don't know if this is correct. Please let me know.

Instructions:
 $ cd examples/ ; make nft-table-xml-add
 # cd test/ ; ./nft-table-xml-add.sh

NOTE: Some kernel changes are required to allow reinsert exactly what is printed (handle handling, flags..)
