Try out a new interface for Umem and Frames #8

Closed tdittr closed 2 years ago

This should make it easier to handle Frames living in Umem similar to a Box<[u8]>. Frames now own the MmapArea in which they live via a shared Arc.

This is not yet finished as all the tests and dev1_to_dev2 examples still need to be converted to the new interface. But it should give an a idea of how a new interface could look like.

MmapArea is sharedly owned by:

all Frames
the Umem that created the area

Umem is sharedly owned by:

all Sockets that were created with it

a Socket is sharedly owned by:

its TxQueue
its RxQueue

This should make sure that there are no dangling Frames or *Queues.
