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.

237604bb07 revise heifload EOF detection 
VipsSource used a unix-style model where read() returns 0 to mean EOF.
libheif uses a model where a separate call to wait_for_file_size()
beforehand is used to check thaht the read will be OK, and then the
read() is expected to never fail.

We were trying to put EOF detection into libheif read(), but that's not
the right way to do it. Instead, test for EOF in wait_for_file_size().

two settings combine if both are given.

but only if necessary
- revise thumbnail autorotate too
