src: xml: consolidate common XML code via nft_mxml_num_parse
This patch moves common XML parsing code to nft_mxml_num_parse().
To handle this, the nft_strtoi() helper fuction is included.
I've changed some MXML_DESCEND[_FIRST] flags to avoid match a nested node under
some circumstances, ie, matching two nodes with the same name that are descendant.
