setopt: avoid integer overflows when setting millsecond values
... that are multiplied by 1000 when stored.
For 32 bit long systems, the max value accepted (2147483 seconds) is >
596 hours which is unlikely to ever be set by a legitimate application -
and previously it didn't work either, it just caused undefined behavior.
Also updated the man pages for these timeout options to mention the
return code.
Closes #1938
