Michael Scott fe84d4f7dd net: http: allow HTTP_NETWORK_TIMEOUT to be configured
Currently, the HTTP_NETWORK_TIMEOUT setting is hard-coded as 20 seconds.
Not every application may want to wait that long, so let's change this
to a CONFIG option: CONFIG_HTTP_CLIENT_NETWORK_TIMEOUT

NOTE: This also removes HTTP_NETWORK_TIMEOUT from the public http.h
include file.  It was not being used externally to HTTP client sources.

Andy Ross 53c859998d kernel: POSIX thread IPC support
Partial implementation of the IEEE 1003.1 pthread API, including
mutexes and condition variables in their default behaviors, and
pthread barrier objects.  The rwlock and spinlocks abstractions are
not supported in this commit (both only make sense in the presence of
multiple SMP processors).

Note that this is the IPC mechanisms only.  The thread creation API
itself is unsupported: Zephyr threads work differently from pthreads
and don't port cleanly in all cases.  Likewise the "_INITIALIZER"
macros from pthreads don't work cleanly here, and _DECLARE macros have
been provided to statically initialize pthread primitives in a manner
more native to Zephyr

Xiaorui Hu eb48a0a73c arm: armv6-m: Support relocating vector table
An abnormal crash was encountered in ARMv6-M SoCs that don't have flash
starting at 0.  With Zephyr OS the reason for this crash is that, on
ARMv6-M the system requires an exception vector table at the 0 address.

We implement the relocate_vector_table function to move the vector table
code to address 0 on systems which don't have the start of code already
at 0.

Of note: _irq_priority_set() isn't called on _ARCH_IRQ_CONNECT(), since

Michael Scott c46c206f8c net: lwm2m: initial library support for LWM2M
Origin: SICS-IoT / Contiki OS
URL: https://github.com/sics-iot/lwm2m-contiki/tree/lwm2m-standalone-dtls
commit: d07b0bcd77ec7e8b93787669507f3d86cfbea64a
Purpose: Introduction of LwM2M client library.
Maintained-by: Zephyr

Lightweight Machine-to-Machine (LwM2M) is a protocol stack extension
of the Constrained Application Protocol (CoAP) which uses UDP
transmission packets.

This library was based on source worked on by Joakim Eriksson,
Niclas Finne and Joel Hoglund which was adopted by Contiki and then
later revamped to work as a stand-alone library.

A VERY high level summary of the changes made:
- [ALL] sources were re-formatted to Zephyr coding standards
- [engine] The engine portion was re-written due to the heavy reliance
  on ER-CoAP APIs which are not compatible to the Zephyr CoAP APIs as
  well as other Zephyr specific needs.
- [engine] All LWM2M/IPSO object data is now abstracted into resource
  data which stores information like the data type, length, callbacks
  to help with read/write.  The engine modifies this data directly (or
  makes callbacks) instead of all of the logic for this living in each
  object's code. (This wasn't scaling well as I was implementing
  changes).
- [engine] Related to the above change, I also added a generic set of
  getter/setter functions that user applications can call to change
  the object data instead of having to add getter/setting methods in
  each object.
- [engine] The original sources shared the engine's context structure
  quite extensively causing a problem with portability. I broke up the
  context into it's individual parts: LWM2M path data, input data and
  output data and pass only the needed data into each set of APIs.
- [content format read/writer] sources were re-organized into single
  .c/h files per content formatter.
- [content format read/writer] sources were re-written where necessary
  to remove the sharing of the lwm2m engine's context and instead only
  requires the path and input or output data specific to it's
  function.
- [LwM2M objects] re-written using the new engine's abstractions

Michael Scott 911efb0e72 net: zoap: use message id for reply matching
In the 08 Feb 2017 V1.0 LwM2M specification page 80 mentions: in
response to a "Notify" operation for which it is not interested in
any more, the LwM2M Server can send a "Reset Message".

Leshan server sends this CoAP RST response and it does not contain
the originating message token (which is also how the packet flow looks
on page 81 of the LwM2M spec).  Using the current ZoAP sources, the
client has no way of matching back to observation which needs to be
cancelled.

Let's add a match for message ID of a reply where there is no token
to handle this case.

Paul Sokolovsky 19ff963693 net: tcp: Allow to explicitly manage TCP receive window
This fixes the existing situation that "if application buffers data,
it's the problem of application". It's actually the problem of the
stack, as it doesn't allow application to control receive window,
and without this control, any buffer will overflow, peer packets
will be dropped, peer won't receive acks for them, and will employ
exponential backoff, the connection will crawl to a halt.

application must explicitly call when it *processes* data, to

Andrew Boie 507852a4ad kernel: introduce opaque data type for stacks
Historically, stacks were just character buffers and could be treated
as such if the user wanted to look inside the stack data, and also
declared as an array of the desired stack size.

This is no longer the case. Certain architectures will create a memory
region much larger to account for MPU/MMU guard pages. Unfortunately,
the kernel interfaces treat both the declared stack, and the valid
stack buffer within it as the same char * data type, even though these
absolutely cannot be used interchangeably.

We introduce an opaque k_thread_stack_t which gets instantiated by
K_THREAD_STACK_DECLARE(), this is no longer treated by the compiler
as a character pointer, even though it really is.

To access the real stack buffer within, the result of
K_THREAD_STACK_BUFFER() can be used, which will return a char * type.

This should catch a bunch of programming mistakes at build time:

- Declaring a character array outside of K_THREAD_STACK_DECLARE() and
  passing it to K_THREAD_CREATE
- Directly examining the stack created by K_THREAD_STACK_DECLARE()
  which is not actually the memory desired and may trigger a CPU
  exception
