nat: nat44-ed cleanup & fixes

Set deprecated option on unsupported API calls.
Cleaned up API calls with deprecated option. Removed
in progress option from long term used API calls.

Removed obsolete/unused nodes, functions, variables.

Fixed set frame queue nelts function. Calling API
would incorrectly not fail even though frame queue nelts
can only be set before first call nat44_plugin_enable.

Moved all formatting functions to _format.c file.

Type: refactor
