Wim Taymans 18776b155b mem: Add tag to memmap 
Add a tag field when creating a memmap so that we can do lookup on it.
This makes it easier to implement the tracking of mappings for io areas.
Remove custom io memory tracking and use the tags.

Add flags to spa_chunk to make data corrupted. The flags on the buffer
stay constant for the life of the buffer. Add flags to mark memory
readable and writable. Mark memory readonly in v4l2-source.

Pass the daemon activation area to the client in the transport event.
This never changes and need to be handled differently from the other
activation areas.

Use the right flags when importing memory.

Add the (desired) memory type to mempool_alloc.

improve some debug.

README 

PipeWire
--------

PipeWire is a server and user space API to deal with multimedia
pipelines. This includes:

  - Making available sources of video (such as from a capture devices or
       application provided streams) and multiplexing this with
       clients.
  - Accessing sources of video for consumption.
  - Generating graphs for audio and video processing.

Nodes in the graph can be implemented as separate processes,
communicating with sockets and exchanging multimedia content using fd
passing.

Building
--------

Pipewire uses the Meson and Ninja build system to compile. If you're not
familiar with these tools, the included "autogen.sh" script will
automatically run the correct meson/ninja commands, and output a Makefile.
It follows that there are two methods to build Pipewire, however both rely
on Meson and Ninja to actually perform the compilation:

$ ./autogen.sh
$ make

or the Meson/Ninja native method:

$ meson build
$ cd build
$ ninja

You can see the available meson options in meson_options.txt file.
