lights_helper: I/O API cleanup
...
* buf => buffer for consistency
* explicitly cast strtol retval to int
* close(NULL) is a no-op, remove superfluous checking
* replace variying buffer sizes by INT_MAX_STRLEN
* always return signed errno codes

lights: Cleanup read/write API
...
* Use O_WRONLY for write
* Return errno for write
* Log all failures
* Fix read_int():
We would always treat strtol(...) = 0 as an error,
although the real value can very well be 0.
Check the end pointer to fix this.
