This API allows initializing the buffer with a given headroom. This
prepares the way for eventually removing the 'reserve_head' parameter
from the net_buf_get APIs, but can already now be useful in some
scenarios where the headroom is desired to be different than some
higher level API sets it to be.

Until now, NET_BUF_POOL() would be opportunistic and allocate a few
more bytes extra for the buffer content if the given size wasn't a
multiple of 4. This is an issue however if the API user really wants
to have a precise size for the buffer so that e.g. net_buf_tailroom
gives meaningful and deterministic results.
This patch removes the opportunistic rounding up, basically leaving it
up to the application to decide if it wants to have unused padding in
the data structure or not.
The crucial thing here is to ensure that locating the user data
section (which is aligned to a 4-byte boundary) doesn't break, since
buf->size is used for that. However, the net_buf_user_data()
implementation already uses ROUND_UP() so the result will still be
the same even if buf->size is not a multiple of 4.

This adds initial timeout handling as described in the spec:
BLUETOOTH SPECIFICATION Version 4.2 [Vol 3, Part A] page 126:
'The value of this timer is implementation-dependent but the minimum
initial value is 1 second and the maximum initial value is 60
seconds. One RTX timer shall exist for each outstanding signaling
request, including each Echo Request. The timer disappears on the
final expiration, when the response is received, or the physical
link is lost.'
Note: As for the actual interval used they are based on the values used
in Linux but in case of disconnect the minimum of 1 seconds was used
to follow the text above.
