90c1fb9a94 Use gcc/clang isnan and isinf builtin functions where available. 
These are used heavily in the building of look-up tables at
start-up time and therefore improve vipsthumbnail perf by ~4%.

66373e9b41 remove exception specs from vips8 C++ interface 
We had exception specs on the C++ interface, but C++11 does not support
them and some compilers have never honoured them. Remove all specs.
Thanks Lovell.

e81900b187 bandjoin is just an instance function 
we had both a class member bandjoin, and an instance member

Vips.Image.bandjoin([i1, i2, i3..])
i1.ibandjoin([i2, i3..])

this was confusing and annoying ... get rid of the class one and just
use bandjoin everywhere, so this is now the way to do it:

i1.bandjoin([i2, i3..])

09a30b602b Use 254 pixels as default tile size 
I remember @benvanik, a friend and colleague, who worked on our DZI renderer (Seadragon) told us that, I believe, it’s better for GPUs to have power of two sized tiles, so 254px + 2 x 1px tile overlap will give you 256 pixel.s

> To keep my tiles nicely sized, I shrink in instead of expand out – that means my tiles are really 254×254 with a 1px border, so the images are 256x256px with 254×254 of useful imagery. If you wanted larger tiles, you’d go 510×510 with 1px border making 512×512 tiles.

253cb8e2e3 fix up dzsave overlap handling 
There was a mixup with the previous fix to dzsave overlap handling,
correct it and update the test suite.

In the previous revision, dzsave overlapped tiles by overlap and sized
them by tile_size. In fact, tiles should be sized as (tile_size + overlap
* 2), ie. tile_size refers to the number of unique pixels per tile.

to rename the instance one as ibandjoin
