Build errors due to change in gnuradio logging scheme.

[murray-lang]

I want to add gr-fcdproplus to my build of gnuradio from the main branch.

There are currently some issues with building gr-fcdproplus against gnuradio main, largely around what appears to be a change in how logging is used, for example GR_CONFIG_LOGGER and LOG are now undefined.

Is an update of gr-fcdproplus on the way?

If not then I am happy to work on it myself, but I have other fish to fry (and a day job) so can wait for while if I know it's coming.

Cheers
