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.

Build a dynamically loadable module for *magick
...
By default, a dynamically loadable module is built for *magick (i.e.
`--with-magick=module`) when:
* ImageMagick or GraphicsMagick is found;
* GModule is supported (`gmodule_supported` pkg-config variable).
This can be overridden on the command line with:
* `--without-magick` - to disable *magick usage;
* `--with-magick[=yes]` - to restore the previous behavior;
* `--disable-modules` - to disable the build of dynamic modules.

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.
See:
https://emscripten.org/docs/porting/guidelines/function_pointer_issues.html

fix a warning from magicksave on some platforms
...
we were leaving delay_gvalue as {0} then unsetting it, which will
produce a warning with some versions of glib.
Thanks chregu.

IM ExceptionInfo were not being freed correctly. This patch
