* reimplement threadpool
just a set of threads that get recycled
"ninja test" passes and dzsave seems to work, though pytest fails for
some reason
* clean up threading code a bit
move base stuff into thread.c, so we have a simple
thread -> threadset -> threadpool
layering
* start trying to revert g_threadpool
based on the original commit
* working!
nice low systime again
still need to repply cnages to threadpool.c since 80e0cc3d1
* reapply fixes from master
so threadpool.c is now up to date
* rename VipsThread as VipsWorker
a bit less confusing
* use a semaphore to count workers in a pool
* tidy up
* formatting
* dynamic threadpool sizing
based on counting the number of blocked threads in each pool
it works, but the improvement is not great :(
* add "concurrency" metadata item
so operators can hint threadpool size (dzsave especially)
* don't use thinstrip for small images
* add RGB mode to openslide
since flatten was taking 20% of CPU time for dzsave
* fix up rgb mode
now actually works
* make the tile buffer per thread
in the new openslideload rgb mode
* fix dynamic pool downsize
* mild refactoring
* fix the buffer system
oops, turned it off by mistake
* all done!
* revise changelog
* Update libvips/iofuncs/threadset.c

* CI: upgrade runner to Ubuntu 22.04
- Compile with GCC 11 and Clang 14.
- Remove redundant PPAs.
- Use system provided Meson.
- Update LeakSanitizer suppressions.
* CI: ensure `VIPS_BLOCK_UNTRUSTED` is tested
`magicksave` cannot be used for testing when building with
`-Dmodules=enabled` (default), since that would require the
loadable modules to be installed first.
* LSan: remove GLib suppression
* LSan: disable the fast unwinder to get full stacktraces
* Move ASan/UBSan fuzzer options to CI configuration
* LSan: remove EOLed python2.7 suppression
* LSan: remove libstdc++ suppression
* LSan: add libx265 to suppression file
* Try to reproduce small memleak
* Try a possible patch
* Skip test if `im_benchmark` is not available
* CI: upgrade Clang version to 13
* CI: correct job names
* Meson: increase the timeout for tests
* README.md: correct Meson invocation
- 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'.
