On ARM, a zero memory address actually falls within the expected bounds
of kernel memory.
Move the NULL check outside the bounds check, so that kernel objects
with NULL memory addresses in the DWARF info (because gc-sections
discarded them) won't confound the script's logic.

To avoid making a system call for every character emitted, there is now
a small line buffer if userspace is enabled. The interface to the kernel
is a new system call which takes a sized buffer of console data.
If userspace is not enabled this works like before.

This path introduce API for retrieving a minimum write-block-size
supported by the flash driver.
This value can differ from the hardware alignment requirement
(as it does for nRF5x).
As the driver has a certain requirement for alignment
when writing, it is necessary to export this value for upper modules
which need to know the write-block-size (for instance, NFFS needs this).

There are several issues with the dev_config union used as a
convenience when calling the i2c_configure api. One, the union is well
name spaced protected and doesn't convey use with just i2c. Second
there are assumptions of how the bits might get packed by the union
which can't be guaranteed. Since the API takes a u32_t lets change in
tree uses to using the macros to setup a u32_t and make the union as
deprecated.

pyocd occasionally throws USB timeout exceptions when running in
VirtualBox, and recently added a command-line option to limit the USB
packet count as a workaround. Introduce an environment variable
PYOCD_DAPARG so Zephyr can pass the argument to pyocd. For example:
$ make BOARD=frdm_k64f PYOCD_DAPARG='limit_packets=True' flash
This workound comes with a performance penalty when flashing and
debugging with pyocd, so it should only be used when running pyocd in
VirtualBox.

The old policy was that objects that are not marked as initialized may
be claimed by any thread, user or kernel.
This has some undesirable implications:
- Kernel objects that were initailized at build time via some
_<object name>_INITIALIZER macro, not intended for userspace to ever
use, could be 'stolen' if their memory addresses were figured out and
_k_object_init() was never called on them.
- In general, a malicious thread could initialize all unclaimed objects
it could find, resulting in denial of service for the threads that
these objects were intended for.
Now, performing any operation in user mode on a kernel object,
initialized or not, required that the calling user thread have
permission on it. Such permission would have to be explicitly granted or
inherited from a supervisor thread, as with this change only supervisor
thread will be able to claim uninitialized objects in this way.
If an uninitialized kernel object has permissions granted to multiple
threads, whatever thread actually initializes the object will reset all
permission bits to zero and grant only the calling thread access to that
object.
In other words, granting access to an uninitialized object to several
threads means that "whichever of these threads (or any kernel thread)
who actually initializes this object will obtain exclusive access to
that object, which it then may grant to other threads as it sees fit."

When the peer slave rejects a Connection Parameter Request
Procedure, the controller proceeds to perform a Connection
Update Procedure without clearing the procedure timer that
causes the connection to terminate eventually. This is

Update Procedure completes.

If a peer master role has support for Connection Parameter
Request Procedure set in its supported features but would
send an Extended Reject Ind as response to the procedure
then the controller incorrectly initiated a Connection
Update Procedure which is not permitted in a slave role.
This would lead to connection timeout after the used instant
in the invalid Connection Update Procedure.
This is fixed by initiating a Connection Update Procedure
only if in a master role.
