Cleanup gettext handling ( #2695 )
...
Use GLib's i18n support instead of copying and pasting that
logic into its own header. This deprecates the vips/intl.h
header in favour of glib/gi18n.h.

always check the return of vips_image_pipeline()
...
For consistency. Although I don't think it can meaningfully fail.

use VIPS_PI instead of M_PI as the former is already defined, added missing includes with their macro protection

create funcs always make MULTIBAND
...
Before, they could make B_W for one-band output. This caused problems
with (for example) two black image bandjoined: the second band then
looked like an alpha to hasalpha() and enabled premultiply/unpremultiply
for operations like affine.
Now, it's always MULTIBAND. This is the generic multiband image type, so
you don't get any unexpected alpha handling.

add VIPS_ONCE and use it everywhere
...
Lovell's idea: save the function call in the most common case

make vips_gaussnoise() pixels reproducible
...
previously, pixel values were regenerated on every calculation, so they
changed on recomputation
pixel values are now generated from the pixel (x, y) coordinate plus a per-call
seed

use round() rather than rint() where appropriate
...
rint() rounds to nearest even, rather than nearest ... in some cases,
like geometry transforms, we want strict nearest
