This series introduces a command-line flag "--by-name" that means
"line-specifier arguments should be interpreted as names.

The patches implement the change for gpioset and gpioget tools. Once we
have settled on an implementation for those tools it could be extended
to other tools, such as gpiomon.

The test suite has been updated to cover the new option.

An initial discussion of the idea was presented here:
