psTimeFromTimeval needs struct

[David.Robbins@…]

the proposed change to psTimeFromTimeval drops the struct from the argument,
const struct timeval *input. The struct needs to be present here unless it is
defined earlier, which it probably shouldn't be since it's not ours and not
used so frequently.

[Paul Price]

"timeval" changed to "struct timeval" throughout (timeval is simply declared
"struct timeval", not "typedef struct {} timeval"):

struct timeval *psTimeToTimeval(const psTime *time);
psTime *psTimeFromTimeval(const struct timeval *input);
