support: Change xgetline to return 0 on EOF
The advantage is that the buffer will always contain the number
of characters as returned from the function, which allows one to use
a sequence like
/* No more audit module output. */
line_length = xgetline (&buffer, &buffer_length, fp);
TEST_COMPARE_BLOB ("", 0, buffer, line_length);
to check for an expected EOF, while also reporting any unexpected
extra data encountered.
