Move the net_buf implementation from the networking subsystem to a library as they have no dependency on the networking subsystem. Network buffers are used in subsystems outside of networking (e.g. Bluetooth, USB). Fixes: #36374 Signed-off-by: Henrik Brix Andersen <henrik@brixandersen.dk>

Enable network buffer pool tracking. This means that:
|
|
* amount of free buffers in the pool is remembered
|
|
* total size of the pool is calculated
|
|
* pool name is stored and can be shown in debugging prints

help
|
|
Alignment restriction for network buffers. This is useful for
|
|
some hardware IP with DMA that requires the buffers to be aligned
|
|
to a certain byte boundary, or dealing with cache line restrictions.
|
|
Default value of 0 means the alignment will be the size of a void pointer,
|
|
any other value will force the alignment of a net buffer in bytes.
