Alexander Motin 9500655e5a Add one-shot mode support to attimer (i8254) event timer.
Unluckily, using one-shot mode is impossible, when same hardware used for
time counting. Introduce new tunable hint.attimer.0.timecounter, setting
which to 0 disables i8254 time counter and allows one-shot mode. Note,
that on some systems there may be no other reliable enough time counters,
so this tunable should be used with understanding.
