Introduce support for target_clones attribute ( #3280 )
...
This requires GLIBC 2.23+, plus either gcc 6+ or clang 14+.
- Provides build-time feature detection
- Use with (un)premultiply for ~10% perf gain on AVX CPUs
- Slightly increases binary size, so best to use sparingly

Improve symbol visibility ( #2688 )
...
* Improve symbol visibility
* Decorate required internal symbols with VIPS_API
* Remove a couple of stray header decls
* Incorporate review comment
- Ensure symbol visibility is also set on static libraries.
- Prefer to use `cc.has_function_attribute('visibility:hidden')`.
* Don't export internal deprecated symbols
* Move deprecated symbols to vips7compat.h
* `IM_FORMAT_H` -> `VIPS_FORMAT_H`
* Move `vips_window_ref` compat stub to `vips7compat.c`
* Disable deprecation warnings internally
* `vips_image_get_kill` -> `vips_image_iskilled`
* Ensure API compatibility
* Add missing include directives
* Move `vips__init` decl to vips7compat
* Move `vips__get_sizeof_vipsobject` to vips7compat
* Fix introspection build
* Fix 2 introspection warnings
* Ensure compatibility with vipsdisp

it seems to fail with MSVC.
int works fine, and is what g_open() uses.

Remove use of varargs in vips_*_open

running on non-native platforms.

better header sniffing for small files
...
vips__get_bytes() used to fail if the file was too small for the
allocated buffer, which was a problem for svg, since files can be extremely
small.
This change makes vips__get_bytes() return the number of bytes read, so
the is_a testers can work on files smaller than the max header size.

make vips_gaussnoise() pixels reproducible

previously, pixel values were regenerated on every calculation, so they

pixel values are now generated from the pixel (x, y) coordinate plus a per-call
seed
