mem_pdu_rx is not runtime resized meaning PDU_RX_SIZE_MIN is no longer
relevant.
Dynamic resizing was a left-over from the old bt controller.
Its size field was only ever set to PDU_RX_SIZE_MIN.
PDU_RX_SIZE_MIN only accounted for advertise PDUs.
So we remove size field from mem_pdu_rx.
However, the rest of the BT controller expects to be able to pull
RX_CNT-number of valid nodes from the pool at init/reset (rx_alloc)
time. This will fail unless we inflate the capacity by one.
To avoid inflation-by-one, mem_* would have to be rewritten to avoid
always-one-extra pattern.

There are issues using lowercase min and max macros when compiling a C++
application with a third-party toolchain such as GNU ARM Embedded when
using some STL headers i.e. <chrono>.
This is because there are actual C++ functions called min and max
defined in some of the STL headers and these macros interfere with them.
By changing the macros to UPPERCASE, which is consistent with almost all
other pre-processor macros this naming conflict is avoided.
All files that use these macros have been updated.

This is a squash merge of commits introducing the new split
Upper Link Layer and Lower Link Layer architecture of the
Bluetooth Low Energy controller.
This introduces a new, improved Link Layer based on the
concept of split responsibilities; The Upper Link Layer
(ULL) is in charge of control procedures, inter-event
scheduling and overall role management. The code for the
ULL is shared among all hardware implementations. The
Lower Link Layer (LLL) is responsible for the intra-event
scheduling and vendor specific radio hardware access.
The communication between ULL and LLL is achieved through
a set of FIFOs that contain both control and data packets.
