[ACTIVITY] report week ending 23 Feb

Progress: * UM-2 [QEMU upstream maintainership] - code review - finished and sent out for review the patchset that provides a 3-phase-reset version of qemu_register_reset() - The MSYS2 project are dropping their support for 32-bit Windows, which affects QEMU because we use them for our "test build on Windows" CI jobs. This prompted us to drop our 32-bit Windows host support (which conveniently we'd already deprecated last year). Sent out patches to drop the CI jobs, document that it's not a supported platform, etc.

thanks -- PMM
