John Cupitt 702ed8298f check for blocked operations on cache lookup
We could return an operation from cache even after the operatuion had
been blocked. This was harmless, but could cause confusion.

CI: remove redundant glib-utils dependency (#3022)

formula has been merged back into `glib`, see:

John Cupitt 19009b15a9 revise loader demand hints
Add a check that header and load methods agree on the demand hint, and
make sure all loaders pass.

If they disagree, you can get bad performance in some cases, since the
pipeline can be built from the header dhint.

move tiff decompress outside lock (#2969)
* 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.

Looks like there's no way to reset the decoder state, so we have to

jxlsave: correctly mark frame as last (#2988)
It's required to close the input, otherwise the encoder can't

Remove even pixel check for J2K subsample_mode auto (#2975)

John Cupitt 29e80ca43f better 0 detection in unpremultiply
We were avoiding /0 by testing for alpha==0, however, this will still
allow very small values of alpha to generate +/- Inf. Instead, check for
abs(alpha)<epsilon.

Fixes some artifacts after unpremul.

John Cupitt 34c17fc3e8 don't minimise after sink_screen expose
We were minimising at the end of threadpool_run, but this was being
called for each sinkscreen render pass, so we were throwing away the
display cache.

Instead, minimise after sink, sink_memory and sink_disc.

To disable DoS limits for JPEG loading. Adding API on a stable branch is
