aebb8af803 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.

0dd6b095aa more conservative hasalpha
The result of hasalpha is used to turn on things like
premultiplication, so we should be rather conservative
about when we signal this. We don't want to premultiply
things that should not be premultiplied.

Check Type as well as bands.

e686614f2c drop incompatible profiles from save
libpng has started throwing hard errors if the profile does not match
the image -- this can happen all the time with perofiles inherited from
images that have been processed.

Test profiles before save and drop them (with a warning) if they are
incompatible with the image.

5176b4a17e better header sniffing for small files
vips__get_bytes() used to fail if the file was too small for the
allocated buffer, which was a problem for svg, since files can be extremely
small.

This change makes vips__get_bytes() return the number of bytes read, so
the is_a testers can work on files smaller than the max header size.

29e05dabaf icc_import attaches the input profile if used
icc_import can take a fallback input profile in case the embedded one is
broken or missing. If we use the fallback profile, this change attaches
it to the output image.

This means that icc_import will always output an image with the icc
profile that was used to import it. This helps to make the behaviour of
`thumbnail` more consistent.

20d840e6da fix a crash with delayed load
If a delayed load failed, it could leave the pipeline only half-set up.
Sebsequent threads could then segv.

Set a load-has-failed flag and test before generate.
