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.

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 .
