Prefer to use flags |= everywhere (#2854) 
Use the bitwise OR assignment operator to ensure that derived
classes does not overwrite the flags from the base class. Also,
move the flags from `openslideload_source` to its base class.

111eef0049 lock progress to 100% on posteval

a9bfd508f5 revise cgifsave checksum 
We were calling it a sum and looking for a change threshold, but really
it's only useful as a checksum and does not have a magnitude. Revise
comments and variable names to reflect this.

It was all mixed up. We don't need to call colourspace -- this is done
for us by the SAVEABLE system.

Pass close-on-exec flag to lcms for non-Windows OS (#2816) 
This ensures child processes do not inherit open file descriptors
and will close a small but long-standing bug reported against
sharp over five years ago.

The change to lcms2 to support this is backwards compatible so
the flag will be ignored by existing versions.

The fopen 'e' flag will soon be part of the POSIX standard, and
is already supported in Linux and BSD. macOS currently ignores
it but will add support soon. Only Windows has a problem with it,
hence the ifdef wrapper.
