util-lib: optionally, when writing a string to a file, verify string on failure
With this change, the idiom: r = write_string_file(p, buf, 0); if (r < 0) { if (verify_one_line_file(p, buf) > 0) r = 0; } gets reduced to: r = write_string_file(p, buf, WRITE_STRING_FILE_VERIFY_ON_FAILURE); i.e. when writing the string fails and the new flag WRITE_STRING_FILE_VERIFY_ON_FAILURE is specified we'll not return a failure immediately, but check the contents of the file. If it matches what we wanted to write we suppress the error and exit cleanly.
