2c5ee332f0 make the buffer recycle list per image 
so now recycle lists are short, scale with pipeline complexity, and
buffers are always appropriately sized for the image instead of being
slowly sized up to the max size for the pipeline

before:

$ vips sharpen k2.jpg x.jpg --radius 20
memory: high-water mark 38.99 MB

after:

$ vips sharpen k2.jpg x.jpg --radius 20
memory: high-water mark 29.46 MB

61068cd03d added vips::init() and vips::shutdown() 
OS X mav was having trouble linking im_init_world() via the C++ API, so
we now have C++ functions for startup and shutdown.

6ae1888ab3 delay region resource unref to reduce malloc churn 
we were unreffing windows and buffers attached to regions on
vips_region_region() etc.

when these regions were reinitialised later, fresh buffers were
allocated causing a lot of churn
