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

John Cupitt 4c5873809f experiment with renaming stream 
rename as VipsConnection, VipsSource, VipsTarget etc.

see https://github.com/libvips/libvips/issues/1494#issuecomment-569498619

```

set -e

edit() {
        sed -i -E "$1" rename
