Introducing CMake is an important step in a larger effort to make
Zephyr easy to use for application developers working on different
platforms with different development environment needs.
Simplified, this change retains Kconfig as-is, and replaces all
Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild
offers is replaced by a set of CMake extentions. These extentions have
either provided simple one-to-one translations of KBuild features or
introduced new concepts that replace KBuild concepts.
This is a breaking change for existing test infrastructure and build
scripts that are maintained out-of-tree. But for FW itself, no porting
should be necessary.
For users that just want to continue their work with minimal
disruption the following should suffice:
Install CMake 3.8.2+
Port any out-of-tree Makefiles to CMake.
Learn the absolute minimum about the new command line interface:
$ cd samples/hello_world
$ mkdir build && cd build
$ cmake -DBOARD=nrf52_pca10040 ..
$ cd build
$ make

Sometimes we need to select Endpoint addresses manually to get it
working with certain USB controllers having limit for endpoints. In
this case default values break endpoint limit check. The proper
solution would be automatic endpoint allocation.

Add a generic function for TCP option parsing. So far we're
interested only in MSS option value, so that's what it handles.
Use it to parse MSS value in net_context incoming SYN packet
handler.

Calculates full TCP header length (with options). Macro introduced
for reuse, to avoid "magic formula". (E.g., it would be needed to
parse TCP options).

MSS is Maximum Segment Size (data payload) of TCP. In SYN packets,
each side of the connection shares an MSS it wants to use (receive)
via the corresponding TCP option. If the option is not available,
the RFC mandates use of the value 536.
This patch handles storage of the send MSS (in the TCP structure,
in TCP backlog), with follow up patch handling actual parsing it
from the SYN TCP options.

For the dummy thread, contents in the mem_domain structure
is insignificant hence setting it to NULL.

During swap the required page tables are configured. The outgoing
thread's memory domain pages are reset and the incoming thread's
memory domain is loaded. The pages are configured if userspace
is enabled and if memory domain has been initialized before
calling swap.

This is intended for memory-constrained systems and will save
4K per thread, since we will no longer reserve room for or
activate a kernel stack guard page.
If CONFIG_USERSPACE is enabled, stack overflows will still be
caught in some situations:
1) User mode threads overflowing stack, since it crashes into the
kernel stack page
2) Supervisor mode threads overflowing stack, since the kernel
stack page is marked non-present for non-user threads
Stack overflows will not be caught:
1) When handling a system call
2) When the interrupt stack overflows

If we are a Friend node with multiple LPNs, we need to iterate through
all available Friendship credentials to find the right keys.

The Mesh spec expects us to fall back to master credentials if
friendship ones are not available. Also remove an unnecessary branch
with the help of a new 'idx' variable.

The friend_cred and new_key information is common for all segments of
a segmented transaction, so it makes sense to store them as part of
struct seg_tx instead of each buffer's user data.
