* correct type
* implement reviewer feedback

* ADded optional output parameter to smartcrop to track the center of
attention.
* Added unit test.
* Added docs & updated changelog.
* Updated argument labels & types in documentation.
* add simple bash completion support
* add "completions" subdir to meson
* start extending completion to extra args
* file complete for every arg after 1
* add completion for enums, file, ints, doubles
* docs, try to improve directory completion
though dir completion is not working correctly, I'm not sure why
* compiles
* note changelog
and switch to FATSTRIP (much quicker)
* don't duplicate header fields in fitssave
be careful not to set records twice in save
see https://github.com/libvips/libvips/issues/3113
* tiny polish
* 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

We'll need something fancier for import.

* Revert "get contiguous RGB(A) buffer directly from VipsRegion"

* rename page_index to page_number
* revise formatting
* move tiff decompress outside lock
Most time in TIFF read is spent in decompression. If we move this
outside the lock, we can get a useful speedup.
This commit adds the machinery to move the lock to before decompress, so
jp2k decompression is now threaded.
Before:
```
$ vips copy wtc.jpg x.tif[tile,compression=jp2k]
$ time vips avg x.tif
117.249845
real 0m15.085s
user 0m16.155s
sys 0m0.109s
```
After:
```
$ time vips avg x.tif
117.249845
real 0m1.207s
user 0m18.384s
sys 0m0.369s
```
* start moving jpg decode outside the lock
* move jpeg decompress outside the lock
seems to work
* add some more tile size checks
double-check jpeg tile size before decode
* fix tiffload demand hinting
We were not setting the hint correctly in header load, and we were not
hinting smalltile for tiled TIFFs.
