progressmeter: protect with a mutex
Progressmeter is protected by the AioContext mutex, which is taken by the block jobs and their caller (like blockdev). We would like to remove the dependency of block layer code on the AioContext mutex, since most drivers and the core I/O code are already not relying on it. Create a new C file to implement the ProgressMeter API, but keep the struct as public, to avoid forcing allocation on the heap. Also add a mutex to be able to provide an accurate snapshot of the progress values to the caller.
