Query available extensions
Sometimes it might be useful to only show a few extensions, such as the most
common ones or only the ones available on a specific computer. Which extensions are available on any given kernel can be determined by querying
the two pseudo files /proc/net/ip tables matches for available match extensions and /proc/net/ip tables targets for possible targets. (As usual
this can also be done using ssh to obtain this information from remote
computers.)
The actual extensions shown should be configurable using the settings
dialog, with an Only Available Extensions quick-configure option.
