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

Cleanup gettext handling (#2695) 
Use GLib's i18n support instead of copying and pasting that
logic into its own header. This deprecates the vips/intl.h
header in favour of glib/gi18n.h.

Enhance the introspection support by fixing annotations (#2655) 
* Ensure that double asterisk characters are only used for gtk-doc comments

This triggers warnings when parsing the files with the introspection scanner
and gtk-doc

* Enhance the introspection support by fixing annotations

Also refine the .metadata file

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]

9246094033 Fix function pointer cast issues 
It is undefined behavior in C and C++ to cast a function pointer
to another type and call it that way. This does work in most native
platforms, however, despite it being UB, but in WASM it can fail.

e48f45187b make RGB and sRGB synonmous 
We had a half-baked idea that RGB could mean generic RGB space and sRGB
would mean strict sRGB interpretation.

Unfortunately, this did not work well in practice. For example,
`icc_transform("srgb")` would tag the result as RGB rather than sRGB
(the converter didn't know it was writing sRGB pixels, it just saw
conversion to RGB with an ICC profile), and then later stages would do
unnecessary icc_imports, or worse, fail.

This patch makes RGB and sRGB strict synonyms. If you want to treat an
RGB image as something other than sRGB, you'll need to do it by hand
with the icc_ functions.
