Johan Hedberg 71c7c01819 net: buf: Remove the need for net_buf_pool_init()
In order to keep the initialization process light-weight, remove
net_buf_pool_init() and instead perform the initialization of the pool
and buffers in a "lazy" manner. This means storing more information
in the pool, and removing any 'const' members from net_buf. Since
there are no more const members in net_buf the buffer array can be
declared with __noinit, which further reduces initialization overhead.

Johan Hedberg c3e08c8fea net: buf: Redesigned pool & buffer allocation API
Until now it has been necessary to separately define a k_fifo and
an array of buffers when creating net_buf pools. This has been a bit
of an inconvenience as well as blurred the line of what exactly
constitutes the "pool".

This patch removes the NET_BUF_POOL() macro and replaces it with a
NET_BUF_POOL_DEFINE() macro that internally expands into the buffer
array and new net_buf_pool struct with a given name:

	NET_BUF_POOL_DEFINE(pool_name, ...);

Having a dedicated context struct for the pool has the added benefit
that we can start moving there net_buf members that have the same
value for all buffers from the same pool. The first such member that
gets moved is the destroy callback, thus shrinking net_buf by four
bytes. Another potential candidate is the user_data_size, however
right not that's left out since it would just leave 2 bytes of padding
in net_buf (i.e. not influence its size). Another common value is
buf->size, however that one is also used by net_buf_simple and can
therefore not be moved.

This patch also splits getting buffers from a FIFO and allocating a
new buffer from a pool into two separate APIs: net_buf_get and
net_buf_alloc, thus simplifying the APIs and their usage. There is no
separate 'reserve_head' parameter anymore when allocating, rather the
user is expected to call net_buf_reserve() afterwards if something
else than 0 headroom is desired.

* Moved networking code into subsys/net.
* Renamed net/yaip to net/ip at the same time.
* Fixed the tests/net to compile
* Fixed the Makefiles and Kconfig files in subsys/net
  to use the new location of the IP stack

Szymon Janc 2f45faba8c net: buf: Use unified k_fifo API for FIFOs
Only net_receive() is using non-special value for net_buf_get_timeout
so this change is included here. Other users are using special values
which are already correctly handling ticks vs ms change.

Anas Nashif d622b09bc0 samples: tests: remove obsolete KERNEL_TYPE and kernel variables
Remove those from Makefiles and testcase.ini, we now support unified kernel
only and sanitycheck script now knows how to deal with this.

Anas Nashif a32579749b ztest: move ztest to unified kernel
ztest was not working with unified kernel and v1 APIs and not many tests are
using ztest right now, so instead of making it work with old APIs, convert it
to unified kernel completely so that new tests written using ztest would be
unified kenrel based.
