a2d196b736 add subifd support to the TIFF writer
A new subifd switch enables the writing of pyramids layers into subifds
(rather than the default successive pages). This switch is enabled
automatically for multi-page pyramids.

seems to work in quick tests

ba0dea001d sort out premultiply rules for upsizing
vips_resize() uses vips_affine() for upsizing and vips_reduce() for
downsizing. Affine automaticaly does a vips_premultiply() for images
with an alpha channel, but reduce does not. This meant that we could
sometimes premultiply twice.

This patch adds a "premultiplied" flag for affine which turns automatic
premultiuplication off, vips_resize() uses this to block affine's auto
premul feature, and the resize docs are clarified to stress that the
operation does not do premultiplication for you.

9cdbf3ee07 don't add fontfiles repeatedly in text
It seems fontconfig will let you add a file repeatedly. This patch adds a
table which is used to block repeated additions and prevents memory growth
and slowdown.

d64385ae99 revise kernel mask calculations
We were seeing small displacements at some shrink factors because of
rounding in the mask size calcualation. This PR takes the rounding into
account when positioning the mask.

cdf0269871 Ensure vips__temp_name creates unique filenames
There was a possible chance that vips__temp_name could generate the
same filename twice if it is called concurrently.

This commit ensures that the serial increment is an atomic operation,
similar to #1211.

- The ASAN suppression parse errors seems to be fixed within Clang 10.
- Fix macOS build by updating the base 'osx_image' to 'xcode11'.
