For now, it was only possible to build plugins using GCC on Windows. However,
windows-aarch64 only supports Clang.

The first patches (already posted and normally pulled) are fixes and
prerequisite to build plugins with meson. They are integrated here because it's
not possible to have two based-on in the cover letter.

Then, we fix compilation warnings on Windows.
After that, we can enable linking with Clang on Windows.

Finally, we enhanced the plugin symbols export list (automatically generated,
and not a static file), and we report some of the information we discovered on
the path in the documentation.

Built and tested on Windows (all msys env)/Linux/MacOS for x86_64 and aarch64
hosts.

Pierrick Bouvier (12):
  scripts: remove erroneous file that breaks git clone on Windows
  contrib/plugins/cflow: fix warning
  meson: build contrib/plugins with meson
  contrib/plugins: remove Makefile for contrib/plugins
  qga: fix -Wsometimes-uninitialized windows warning
  qga: fix missing static and prototypes windows warnings
  win32: use compiler option instead of attribute gcc_struct
  plugins: enable linking with clang/lld
  plugins: add missing export for qemu_plugin_num_vcpus
  plugins: detect qemu plugin API symbols from header
  plugins: eradicate qemu-plugins.symbols static file
  docs: add information on how to setup build environments
