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.

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.

Thanks barryspearce

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.

9bb86119e3 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.
