[bind10-dev] layout of build system

I do have a mild preference for not using a src directory; I prefer a
flatter tree structure with bin and lib at the top level.  If we do use a
src directory I'd prefer to flatten that: i.e., get rid of the bin and lib
layer, and just have src/datastore, src/auth, src/boss, etc.  But whatever.

I suggest 'cmdchan' or similar instead of 'CC', as CC makes me think that's
where all the C++ code goes.

I'm not clear on what 'libexec' is for.  Is it like bind9/util, i.e.,
utilities to support the build process?  Or something else?  It's not a
very intuitive name, to me.

Otherwise fine.
