Using macros does not let the compiler verifying about the type we are
providing, which usually give an error easier to understand.
Also, this will let the compiler deciding how to actually optimize
(inline or not) the code.

Provide an utility function that pushes data down in the fragment
chain which means that there would be some free space before the
first fragment.

Provide a function that checks if there is any free space
in the individual fragment and remove such slack. If there
are fragments that would become empty, then those fragments
are removed from the fragment list and freed to the fragment
pool.

This function will copy desired amount of bytes from one
fragment list to another. Caller can specify amount of
bytes reserved in front of the new fragment list.

It is possible that net_buf_get() will return NULL
as the allocator can be called in ISR context.
In this case we much return and not overwrite kernel
memory.

Instead of calling net_buf_get() with reserve_head > 0, we now
call it with reserve_head = 0. The reason for this is that the
reserve space is not meant for protocol data. So instead the
ll header space is allocated using net_buf_add() followed by
net_buf_pull() which will have the same effect and set the
buf->data pointer to point to start of the L3 layer.

The fix prevents the net_nbuf_unref() from removing fragment
list if the top level net_buf is not removed.

User should use the net_nbuf API that is supporting a concept
of RX, TX and DATA buffers, instead of using directly the net_buf
low level API.
