guix/store/build-derivations.scm: new module.

* guix/build/store-copy.scm (<store-info>): export so that (match x ($ <store-info> ...) ...) will work. * guix/store/build-derivations.scm: new module (note: WIP). (get-output-specs, builtin-download, add-to-trie, make-search-trie, remove-from-trie!, scanning-wrapper-port, scan-for-references, ensure-input-outputs-exist, build-derivation): new procedures. (builtins): new variable. (<trie-node>): new record types. * Makefile.am: add guix/store/build-derivations.scm to STORE_MODULES.
