services: Rewrite using gexps.
* gnu/services.scm (<service>)[inputs]: Remove. * gnu/system.scm (links): Remove. (etc-directory): Add PASSWD and SHADOW to #:inputs. (operating-system-boot-script): Pass ETC to 'dmd-configuration-file'. (operating-system-derivation): Remove EXTRAS from the union. * gnu/system/linux.scm (pam-service->configuration): Rewrite in terms of 'gexp->derivation'. Compute the contents on the build side. Expect 'arguments' to contain a list of gexps. (pam-services->directory): Rewrite in terms of 'gexp->derivation'. (unix-pam-service): Change 'arguments' to a list of one gexp. * gnu/system/shadow.scm (<user-account>)[inputs]: Remove. [shell]: Change default value to a gexp. (passwd-file): Rewrite in terms of 'gexp->derivation'. Compute contents on the build side. * gnu/services/base.scm (host-name-service, mingetty-service, nscd-service, syslog-service, guix-service): Change 'start' and 'stop' to gexps; remove 'inputs' field. (guix-build-accounts): Change 'shell' field to a gexp. * gnu/services/networking.scm (static-networking-service): Change 'start' and 'stop' to gexps; remove 'inputs' field. * gnu/services/xorg.scm (slim-service): Likewise. * gnu/services/dmd.scm (dmd-configuration-file): Expect ETC to be a derivation. Change 'config' to a gexp. Use 'gexp->file' instead of 'text-file'. * doc/guix.texi (Defining Services): Update nscd example with gexps, and without 'inputs'. Add xref to "G-Expressions".
