icc_import and _transform now test the embedded profile more carefully.
It must now be a valid profile and must be compatible with the image.

66f1b4408c never use tiff memcpy mode for ycbcr images 
We were still using memcpy mode for some strip YCbCr images. Clean up
read var naming to make the logic easier to follow.

1f100c0c42 better buffer sizing in tiff reader 
We were not setting JPEGCOLORMODE_RGB early enough, so buffers could be
undersized in some circumstances.

Thanks omira-sch.

33d90b5e26 only enable sanity checks in debug mode 
We had a couple of sanity checks always on. As a result, libvips could
get slow for large pipelines.

Move them into g_assert().
