fsm: Allow millisecond granularity in osmo_fsm built-in timer

So far, the public API of osmo_fsm only allowed integral seconds as
timeout.  Let's change that to milli-seconds in order to cover more
use cases.

This introduces
* osmo_fsm_inst_state_chg_ms()
* osmo_fsm_inst_state_chg_keep_or_start_timer_ms()

Which both work exactly like their previous counterparts without the _ms
suffix - the only difference being that the timeout parameter is
specified in milli-seconds, not in seconds.

The value range for an unsigned long in milli-seconds even on a 32bit
platform extends to about 48 days.

This patch also removes the documentation notice about limiting the
maximum value to 0x7fffffff due to time_t signed-ness.  We don't use
time_t but unsigned long.
