acc579cc9d force binary mode for connections on win 
stdin / stdout (for example) are created in text mode by default on
win. We need to flip them to binary mode for connection read and write.

91d9610a55 fix out of bounds read in tiffload 
libtiff can change the value of some fields while scanning a corrupt
TIFF file and this could trigger an out of bounds read.

This patch makes tiffload more cautious about rescanning a TIFF
directory before reading out header fields.

0ee8b1e844 improve seek on pipes 
There were a few issues in VipsSource around seeking on pipes. With this
patch, EOF detection is better, and pipe sources automatically turn into memory
sources when EOF is hit.
