53dac98b55 larger seq cache 
Make the seq cache 50% larger to allow for rounding with some image
widths, tile sizes and thread numbers.

e1baf66f19 "squash" to tiffsave now does lab as well 
The "squash" option to tiffsave now also squashes 32-bit 3-band float
CIELAB images down to 8 bits.

fix: do not try to use "undefined" delay 
Expression could be truthy even when no `delay` was provided by user.

Now, the `delay_length` is 0 by default to avoid this situation.

8f95b08218 put seq access back in to tilecache 
We removed seq mode from tilecache a few months ago as part of a
simplification, but it turns out it's needed for vips_sequential().

1fd3b478e1 always check memory area length 
vips_image_new_from_memory() allowed you to use length == 0 to mean
"don't check memory length". This was part of some very old vips7
compatibility.

The ppm loader could pass length == 0 if header size was equal to file
size, bypassing the length check.

e236f19f97 add fallbacks to new_from_stream 
If the stream-based loaders fail, vips_image_new_from_stream() now falls
back to the old file and buffer loaders.

The file and buffer loaders already try the stream loaders first.

a382359e65 don't test features in unminimise 
This was circular: test features needed an unminimised stream, but
unminimise used to test features.

ec7aa1d6b6 delay testing stream properties until we have to 
This makes stream object creation simpler: you don't need to have
everything set up before build occurs, so you can attach signal handlers
for read and seek later.

d88ce970b7 make operation cache invalidation advisory 
This patch makes operation cache invalidate advisory rather than
immediate. Operations set a mark on cache entries meaning "this entry is
no longer valid", then the entry is removed next time the operation
is looked up.

This breaks the loop (now the cache can remove operations, but operations
can't remove cache entries), so it should be safer (I think). Everything
is inside a mutex, at least.

acd9101037 always copy before exif_update 
During write, we often call vips__exif_update(). This updates the exif
block from the other image metadata prior to save.

Always copy the image before calling this.

20cee5d041 block metadata changes on shared images 
If images are shared (ref count > 1), block changes to the set of
metadata items on the image. These can cause crashes in highly threaded
programs.
