Add support for TIFFOpenStream

Dear GeoTIFF Folks,

    I would like to use the C++ stream code in libtiff
(tiffio.hxx, 
tif_stream.cxx) for file i/o.  libxtiffio supports every
method of 
opening a TIF other than this.  At least two solutions come
to mind:

    1) One of the developers comes up with a nice way to add
the 
TIFFStreamOpen() functions.

    2) Make _XTIFFInitialize() public.  Since this is the
only thing 
special about the XTIFFOpen() functions, it is just as
simple to allow 
the client code to call it, and then use whatever TIFFOpen
it wishes.

Fred,

The stream support in libtiff has been a nightmare, and not
something
I want to introduce into libgeotiff.

Feel free to submit a bug report with the patch to make this
public and
I will incorporate it.

Best regards,

Frank,

    I submitted bug report #1296 with the patch attached. 
Could you
look at and see if it can be applied?  This would really be
helpful to
me, because I am preparing my software for release, and
would really
like to avoid shipping a specially modified library with it.

Fred,

I have reviewed and applied your patch.  I apologize for the
delay.

Thanks!

Do you plan to roll another public release soon?  Best I can
tell, the 
last one is 1.2.3 in 3/06.

Fred,

I have no imminent plans for a release.  I'd imagine the
next release would
be driven by newer EPSG datasets.

Frank,

It would be a bit easier to distribute my application if it
worked with 
a released version of geotiff.  As it stands, I'll need to
either refer 
users to CVS or include a tarball of it in the distro.  This
is OK, and 
I understand why you might be reluctant to cut a revision
just for my 
minor change, but it sure would be convenient.
