=== nft_ctx_output_get_numeric() and nft_ctx_output_set_numeric()
These functions allow control over value representation in library output.
For instance, port numbers by default are printed by their name (as listed in '/etc/services' file), if known.

-=== nft_ctx_output_get_literal() and nft_ctx_output_set_literal()
-The literal setting controls whether reverse DNS lookups are performed for IP addresses when printing them.
-Note that this may add significant delay to *list* commands depending on DNS resolver speed.

=== nft_ctx_output_get_debug() and nft_ctx_output_set_debug()
Libnftables supports separate debugging of different parts of its internals.
To facilitate this, debugging output is controlled via a bit mask.
