monads: Move '%store-monad' and related procedures where they belong. This turns (guix monads) into a generic module for monads, and moves the store monad and related monadic procedures in their corresponding module. * guix/monads.scm (store-return, store-bind, %store-monad, store-lift, text-file, interned-file, package-file, package->derivation, package->cross-derivation, origin->derivation, imported-modules, compiled, modules, built-derivations, run-with-store): Move to... * guix/store.scm (store-return, store-bind, %store-monad, store-lift, text-file, interned-file): ... here. (%guile-for-build): New variable. (run-with-store): Moved from monads.scm. Remove default value for #:guile-for-build. * guix/packages.scm (default-guile): Export. (set-guile-for-build): New procedure. (package-file, package->derivation, package->cross-derivation, origin->derivation): Moved from monads.scm. * guix/derivations.scm (%guile-for-build): Remove.
