John Cupitt d3ccadf212 revise unpremultiply, again
We were not detecting division by zero carefully enough, nor clipping
the alpha range sufficiently in unpremultiply.

John Cupitt 3996f3279b fix range clips for casts to and from int
Fix two bugs:

- clip in casts from int32 and uint32 could overflow -- do these as gint64 now

- clip in casts from float to int could overflow since float32 can't
  represent the full range of int32 without losing precision -- do these
  as double

And add some more tests.

Thanks ewelot.

John Cupitt 2585565b3e better test for output to target
We used to enable write to stdout if the first character of an output filename
was ".", eg.:

	vips copy x.jpg .png

But this will also enable write to stdout for things like:

	vips copy x.jpg ./y.png

This patch also tests that the rightmost "." in a filename is also the
first character.

John Cupitt 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.

John Cupitt 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.

John Cupitt 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().
