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.

77365a8a6f better handling of JFIF res unit 0 
res unit 0 sets the aspect ratio, rather than being unitless

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.

6fc2015783 Remove use of varargs in vips_*_open 
This matches the declaration of g_open and helps tools (such as ASan) when
running on non-native platforms.

efd62acccd better iiif tile naming 
We were clipping edge tiles against the size of the scaled up layer.
Instead, clip against the size of the top level image.

5f7502ebf7 Upgrade Python and Clang to latest version on Travis 
- Python 2.7 reached the end of its life on January 1st, 2020.
- The ASAN suppression parse errors seems to be fixed within Clang 10.
- Fix macOS build by updating the base 'osx_image' to 'xcode11'.

6f0548dc5c thumbnail could fail on HEIC in some modes 
in locked UP or DOWN mode, vips_thumbnail() could incorrectly select the
thumbnail from a HEIC image even when it was not large enough to
generate the output image.

clients to use this.
