Introduce close_safely helper function (#763)

The helper function centralizes some extra checks and diligence desired
by many/most current code paths but currently inconsistently applied.
This includes bypassing the close call when the file descriptor is -1
already, resetting the file descriptor variable to -1 after closing, and
preserving errno.

All calls to close are replaced by close_safely. Some warning log output
is lost over this, but it doesn't seem like this was very useful anyways
given that Linux always closes the file descriptor anyways.
