This helps simplify code that was previously combining net_buf_add()
with memcpy().

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.

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.

Fix compilation issues that show up if SYS_LOG is mapped to printk
instead of printf. Unlike printf, printk is annotated so that the
compiler catches incorrect format specifiers passed to it.

This fixes warnings related to the use of nano_work and
nano_delayed_work in ATT layer.
Note that k_delayed_work takes a timeout in miliseconds rather than in
ticks thus the timeouts values changes.

When retrying the request due to a security error that can fail but since
the original buffer was freed in the process the code can no longer verify
if the opcode matches thus it always fails BT_ATT_ERR_UNLIKELY instead of
using the response error, so this not longer cares about the opcode and
just use the response error always.
