Implement timers and destination URLs.
* gconf/gconf-gram.y (stmt_end): Make sure end callback is called in the same environment as the begin one. * src/vtab.c, src/null.c, src/timer.c: New files. * src/Makefile.am (wydawca_SOURCES): Add new files. * src/config.c (cb_mailer): Remove useless check. (cb_destination_url): New function. (directory_kw): Change handling of the destination keyword. (cb_directory): Rewrite final checks. * src/directive.c, /src/process.c, src/triplet.c: Add timers. * src/diskio.c (move_file, archive_file, symlink_file, rmsymlink_file): Prefix with dir_. * src/mail.c (mail_stats): Add timer meta-variables. * src/wydawca.c (make_stat_expansion): Change definition. * src/wydawca.h (struct virt_tab): New data type. (struct directory_pair.dest_url): New member. * tests/upload-dry.at: Update expected output.
