call: Fix race condition between select(2) and signal delivery.

If a signal is delivered between the start of the main select loop and select
might wait for a long time.  Fixing this with select is not possible so
switch to pselect.

Unlike select pselect akes a struct timespec pointer as its argument so
rewrite the related infrastructure to work with struct timespec instead of
struct timeval.

For now the race did only affect the SIGQUIT delivery.
