(Note getsecs() is used only in network code, so
 it won't affect bootxx for disks which would have ~8KB limit)

Preparing a full 32 bit value in getsecs() could also
make the function larger.

On the other hand, some MD getsecs() values would wraparound
at !powerof2() value like 86400, so there is no proper way
for MI code to handle wraparound case with current code
even if we make it uint16_t.
(though it won't happen so often, ~once per a hour or per a day?)

Anyway, I'll make getsecs() returns (unsigned) satime_t
as christos suggested, so we can decide it later.

The target is to remove 64 bit time_t from standalone code :-)
