b96ed28903 update docs for vips_shutdown() use
Since we have a new policy.

experiment with removing shutdown from atexit (#2439)
remove shutdown from atexit

Because atexit() can be called at almost any point during process termination,
including after worker threads have been force-quit, we can't use it for
cleanup.

New policy: use vips_shutdown() explicitly if you need to clean up,
though it's optional. Only use atexit() for leak checking.

15416c410d raise the PNG text chunk limit
Raise the PNG text chunk limit to 50, since it seems some real images
have a text chunk per line of exif data.

Fix flatten clip (#2432)
* fic gtk-doc typenames in cgif

* fix flatten clipping

flatten could produce out of range values if max_alpha was less than
the limit of the numeric range of the format

Fix UBSan errors (#1948)
* Ensure UBSan exits with a non-zero code on error

* Avoid misaligned member access in mosaic_fuzzer

* Add missing VIPS_CLIP in scRGB2sRGB/scRGB2BW

* Fix UBSan error in flatten

By using saturated casts for the int types (copied from vips_cast).

* CI: ensure fuzzer log is printed on error

* Avoid UB in heifload

* Revert flatten change

I could no longer reproduce this with clang 12 locally.

* Indentation fixes [skip ci]

gifsave: expose bitdepth property (#2429)
Provides control over the maximum number of colours in the output
image palette, making the API more closely match that of pngsave.

Lowering the bitdepth to 7 (from the default value of 8), which
halves the maximum number of colours from 255 to 127, typically
reduces encoding time by ~20%.

cfd9dc3f01 try to handle mmap failing in source
Some filesystems have mmap disabled. Make vips_source_map() fall back to
read if mmap fails.

CI: resolve failures and various improvements (#2426)
* Simplify CI workflow

* CI: upgrade Ubuntu's Clang version to 12

* CI: upgrade macOS runner to version 11 (Big Sur)

* CI: temporarily disable the M1 runner

* CI: output test suite log upon failure

* CI: avoid brew update/upgrade steps

Since it may take a long time.

* CI: all jobs are supposed to succeed

* Fix test_descriptors.c failure after f8c2a36

Use a RANDOM image to create many crops from one source.

f8c2a36746 arrayjoin signalling minimise also frees memory
By making the sequential line cache non-persistent, and only minimising
when the read point is well past the image.

On large arrayjoin operations, this saves many GB of memory.

a20cd4cdc1 minimise arrayjoin inputs during processing
arrayjoin with a sequential pipeline will now minimise inputs when they
are no longer being used. This drops the number of open file handles
needed to construct large arrays.

Sadly, memory savings are minimal.

99724e6097 safer stop-early logic in tilecache
Don't actually stop the tilecache loop early, since that could deadlock,
instead just stop fetching from the pipeline.
