services: messaging: Prosody config supports file-like objects.
* doc/guix.texi (Messaging Services): Update accordingly. * gnu/services/configuration.scm (serialize-configuration, serialize-maybe-stem, serialize-package): Return strings or string-valued gexps (these procedures were only used for their side-effects). * gnu/services/messaging.scm (serialize-field, serialize-field-list, enclose-quotes, serialize-raw-content, serialize-ssl-configuration, serialize-virtualhost-configuration-list, serialize-int-component-configuration-list, serialize-ext-component-configuration-list, serialize-virtualhost-configuration, serialize-int-component-configuration, serialize-ext-component-configuration, serialize-prosody-configuration): Return strings or string-valued gexps and stop printing. (prosody-activation): Use SERIALIZE-PROSODY-CONFIGURATION's return value with MIXED-TEXT-FILE instead of using its output with PLAIN-FILE. (serialize-non-negative-integer, serialize-non-negative-integer-list): Convert numbers to strings. (file-object?, serialize-file-object, file-object-list?, serialize-file-object-list): New procedures. (ssl-configuration)[capath, cafile], (prosody-configuration)[plugin-paths, groups-file]: Replace FILE-NAME with FILE-OBJECT. * guix/gexp.scm (file-like?): New exported procedure.
