gexp: Add 'with-imported-modules' macro.
* guix/gexp.scm (<gexp>)[modules]: New field. (gexp-modules): New procedure. (gexp->derivation): Use it and append the result to %MODULES. Update docstring to mark #:modules as deprecated. (current-imported-modules, with-imported-modules): New macros. (gexp): Pass CURRENT-IMPORTED-MODULES as second argument to 'gexp'. (gexp->script): Use and honor 'gexp-modules'; define '%modules'. * tests/gexp.scm ("gexp->derivation & with-imported-modules") ("gexp->derivation & nested with-imported-modules") ("gexp-modules & ungexp", "gexp-modules & ungexp-splicing"): New tests. ("program-file"): Use 'with-imported-modules'. Remove #:modules argument to 'program-file'. * doc/guix.texi (G-Expressions): Document 'with-imported-modules'. Mark #:modules of 'gexp->derivation' as deprecated. * emacs/guix-devel.el: Add syntax for 'with-imported-modules'. (guix-devel-keywords): Add it. * .dir-locals.el: Likewise.
