libchromeos: Make KeyValueStore support multiline values.

Make the KeyValueStore class support using trailing
backslashes to extend values across multiple lines, e.g.

  key=here is a really long value. there's really no good \
      reason for it to be this long.

Also tighten validation:
- report failure for lines with empty keys
- report failure for lines without equals signs
- trim leading and trailing whitespace around keys
- permit leading whitespace before comments
