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.

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.

Ensure vipsload only byte swaps if necessary
...
Prior to this commit, MSB-ordered vips images were always byte swapped
on both little- and big endian systems. And LSB-ordered vips images
were loaded without a byte swap. This works correctly on little endian
systems, but will not work on big endian systems where the byte swap
must be done vice versa.
This commit ensures that the byte swap only takes place when needed.
See https://github.com/libvips/libvips/issues/1847 .

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().
