Marcus Shawcroft 954baea90b random: Restructure RANDOM Kconfig
Restructure the RANDOM Kconfig to match the structure used in other
drivers with a single top level menu.  Move the true random number
generators to appear first in the menu, with pseudo generators at the
bottom.  Do not present pseudo generators if a true random generator
is presented.

This change implies that tests, samples and applications that require
the random driver interface must now select CONFIG_RANDOM_GENERATOR.

In order for tests and samples to build (and run) on platforms that
have no random driver it remains necessary to select
the CONFIG_TEST_RANDOM_GENERATOR.

Note that CONFIG_TEST_RANDOM_GENERATOR retains its original purpose of
enabling a random driver that delivers non random numbers for the
purpose of testing only.

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.

Jukka Rissanen 3eaec41ab8 net: Moved net/ to subsys/net
* 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

As the native IP stack is now the default, there is no need
for corresponding Kconfig option.

Tomasz Bursztyka d02a9692ff wpan_serial: Minimize debug output by default and set proper nbuf size
Nbuf data size needs to be set to 128 bytes, specifically for wpan
sample.

Debug output kills timing, and thus can generate spurious failures on
reception, so limiting it to errors by default.
