Mark Mentovai 583233cf78 Add FileReaderInterface. Move StringFileWriter to StringFile and
implement the new interface.

The upcoming minidump reader will get minidump data from a
FileReaderInterface. For ease of testing, a string-based implementation
is provided. There wasn’t a good reason to have a separate
StringFileReader and StringFileWriter, so I combined them into a single
StringFile.
