Problem was: readline writes out-of-bounds, corrupts memory.
Problem was: readline seeks on files that don't support seek.
Problem was: readline fails to detect seek errors, returns garbage.
Problem was: readline wildly inefficient, re-reading same data
again and again.
Add utility to test for read/write bugs.
Replace readline with a version that is more compact, more
maintainable, more extensible, more correct, more efficient, and
able to read from named FIFOs and other things that don't seek.

======================================================
The code in sg_file.cxx appears to run parallel to code
in other places such as sg_socket.cxx I wouldn't be
surprised if the other places needed fixing, too ...
but I haven't looked.
