Richard Levitte dab2cd68e7 apps: Don't include progs.h in apps.h 
Everything in apps includes apps.h, because that one declares apps
internal library routines.  However, progs.h doesn't declare library
routines, but rather the main commands and their options, and there's
no reason why the library modules should include it.

So, remove the inclusion of progs.h from apps.h and add that inclusion
in all command source files.
