Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.
Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.
Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file. Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

This commit introduces a very light-weight and lock-less
scheduling of the Controller's deferred function calls
called the Mayfly.
Earlier work implementation used in the Controller had an
O(n) to schedule a function in a linked list that used IRQ
lock during modification of the linked list in the
Controller's ISR executions.
Mayfly is a compile time configurable matrix of queues
where an execution context-safe queue exists between two
execution context, one being the caller and the second
being the callee. Callee(s) are run in a software interrupt
but can also be run in an OS thread.
There are minor clean ups too in this commit related to
folder structure.

On CPUs like nRF51 which run at 16MHz, certain BLE control
procedure PDU processing take more CPU time than permitted
inside tIFS (150us). Current implementation of Data Length
Update procedure does not span over multiple connection
interval (unlike Encryption Setup, which is another control
procedure processing that would consume more CPU time)
hence taking more CPU time inside tIFS on nRF51.
During the radio ISR, the active clock and packet timer are
active and it is used to profile the CPU time taken which
is used to decide on whether there is sufficient time in
the current radio event to process the control packet.
This commit also fixes a potential bug that would cause
disconnection due to MIC failure on encrypted connections
that performed Data Length Update. Controller used to NACK
the request/response PDU if it was not in a state to resize
the receive buffers but did not reset the CCM counter. This
is now fixed by the change done to NACK control PDU based
on available CPU time in radio ISR.

Move controller code from drivers/controller to
subsys/bluetooth/controller.
