(sig_on_signal): Add SA_RESTART if appropriate.
(oop_signal_new): Don't just blindly set FD_CLOEXEC and
	O_NONBLOCK.  Read the old settings first.
(oop_signal_use_sa_restart): New function.

(setup_timer): Ditto.
(garb_callback): Moved to text-garb.c.
(saver_callback): The source argument is actually used.
(toploop): Moved the garb timer to text-garb.c.
(server_idle): New function.

(setup_timer): Ditto.
(server_idle): New function.

(server_init): Use oop_signal_new, since I don't trust the way
	liboop uses siglongjmp to break out of a signal handler.
	Ignore the signals before registering them with liboop, to get
	a proper behaviour on shutdown.
(main): Adjusted to use the signal adapter.

(garb_timer_running): Ditto.
(garb_text): Added static qualifier.
(garb_callback): Moved here from connections.c.  Some minor
	modifications made to make it compiler in its new
	environment.
(start_garb_thread): New function.
(stop_garb_thread): New function.
(start_garb): Restart the garb "thread".

(start_garb_thread): New function.
(stop_garb_thread): New function.

parameters and penalty points/client scheduling.  Added test cases for
parsing of timeval values.  Improved timeval parsing.  Improve config
file checking.

(Parameters): Updated the documentation for "timeval" parameters
	and the parameters relating to penalty points.

	Round the tv_usec field properly.

(dump_timeval): New static function.
(dump_cfg_timevals): New request.

files that needs to include either file now does so via this wrapper.

	Break overly long lines.

optional suffix such as "hours" appended.  Store them as a struct
timeval, not as an int, so that the bulk of the code doesn't have to
take the unit into account.  Use "struct timeval" instead of a number
of milliseconds or seconds in several places.  This fixes a number of
potential and actual overflows.  Added utility functions for struct
timeval.

(create_text_add_miscs): Ditto.
(do_create_text): Ditto.
(add_recipient): Ditto.
(add_comment): Ditto.
(add_footnote): Ditto.

(sync_part): Return a struct timeval instead of a long.  Use
	struct timeval instead of a time_t.  Use timeval_remaining()
	to simplify the code.
(init_cache): Use a struct timeval instead of time_t.
(cache_sync_all): Adjusted to new API of sync_part().

(login_old): Ditto.
(login): Ditto.
(get_static_session_info): Ditto.
(get_time): Ditto.
(logout): Ditto.  Use timeval_diff_sec instead of ldifftime.
(who_is_on_dynamic): Use timeval_diff_sec instead of ldifftime.
(get_session_info): Ditto.
(get_session_info_ident): Ditto.

	timeout", "Sync timeout", "Garb interval", "Sync interval" and
	"Sync retry interval" from int to timeval, and added
	appropriate default suffixes to those configuration
	parameters.

(main): Adjusted for the new type of current_time.

(do_add_member): Ditto.

(dump_statistics): Ditto.
(saver_callback): Ditto.
(setup_timer): Replaced the milliseconds argument with a struct
	timeval argument.
(garb_callback): Simplified the code.
