after some discussion on discord with the libjxl maintainers
see https://github.com/libvips/libvips/issues/2830
to do: save scrgb to eg. JPEG fails right now :( we need to do
scRGB->sRGB in jpegsave
* 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.
- Remove `HAVE_LCMS` definition in favor of `HAVE_LCMS2`.
- Remove `HAVE_WINDOWS_H` definition in favor of `G_OS_WIN32`.
- Remove stray `vips_text_get_type` in `conversion.c`.
- Remove duplicated `unistd.h` include.
- Remove redundant `strcasecmp` definition, we use `g_ascii_strcasecmp` everywhere.
- Remove unnecessary header checks in `configure.ac` and `meson.build`.
- Ensure `unistd.h` include is guarded with `HAVE_UNISTD_H`.
- Fail early when `-Dfontconfig=enabled` and `pangoft2` is not found.
Use the bitwise OR assignment operator to ensure that derived
classes does not overwrite the flags from the base class. Also,
move the flags from `openslideload_source` to its base class.
* flag to save bmp with bitdepth 1
* magicksave: add bitdepth option

* doc: add missing files and use full paths
It seems that private_headers didn't work for out-of-tree builds.
This commit makes it use full paths and adds a few missing files.
* cplusplus: use the correct `install_dir` for the Doxygen docs
We were calling it a sum and looking for a change threshold, but really
it's only useful as a checksum and does not have a magnitude. Revise
comments and variable names to reflect this.
* save GIF palette as metadata
... if there are no local colour tables.
See https://github.com/libvips/libvips/issues/2576
* cgifsave: reuse global palette, if possible
* add reuse_palette parameter
* add reoptimise parameter and reuse palette by default
* attach global palette even if local palettes are present
* add check for presence of use-lct
* Revert "add check for presence of use-lct"
This reverts commit cd0f14e45e8bed8f108ee9666e2569c6355f17eb.

This ensures child processes do not inherit open file descriptors
and will close a small but long-standing bug reported against
sharp over five years ago.
The change to lcms2 to support this is backwards compatible so
the flag will be ignored by existing versions.
The fopen 'e' flag will soon be part of the POSIX standard, and
is already supported in Linux and BSD. macOS currently ignores
it but will add support soon. Only Windows has a problem with it,
hence the ifdef wrapper.
