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.

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.
