Ravi kumar Veeramally 1e47f26d1c net: coap: Remove legacy CoAP implementation
As we are removing net_app and net_pkt based libraries and
applications, CoAP legacy based libraries and apps are moved
to socket based implementations. So removing legacy CoAP.

When walking through the coap resources in coap_handle_request, return
-EPERM if a resource exists but does not have the request method. This
allows the caller to catch the error and return a 4.05 message.

Jukka Rissanen 86689030e8 net: Clarify logging in networking code
Remove network specific default and max log level setting
and start to use the zephyr logging values for those.

Remove LOG_MODULE_REGISTER() from net_core.h and place the
calls into .c files. This is done in order to avoid weird
compiler errors in some cases and to make the code look similar
as other subsystems.

Taehwa Kang 2bdc5923ad net: coap: Fix Coap coap_option_value_to_int and coap_append_option_int
In coap_option_value_to_int function, when coap option length is 4,
option->value[3] should be shifted by 0 rather than option->value[2].
This doesn't affect the behavior of function but needs to be fixed.

In coap_append_option_int function, when the value is between 0xffff
and 0xffffff(when option length is 3), bit shift operation is wrong.
For example, if the value is 0xABCDEF, by sys_put_be16(val, data)
data[0]=0xCD, data[1]=0xEF, by val >> 16, data[2]=0xAB. So the result
becomes 0xCDEFAB not 0xABCDEF. So, to sys_put_be16 function hand
&data[1] over instead of handing data over and val >> 16 needs to be
set to data[0], not data[2].

Ulf Magnusson 1073882998 subsys: kconfig: Remove 'default n' properties and clean up a bit
Bool symbols implicitly default to 'n'.

A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though.

Remove some 'default ""' properties on string symbols too.

Also make definitions more consistent by converting some

  config FOO
  	<type>
  	prompt "foo"

definitions to a shorter form:

  config FOO
  	<type> "foo"

This shorthand works for int/hex/string symbols too, not just for bool
symbols.

Sebastian Bøe 12f8f76165 Introduce cmake-based rewrite of KBuild
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

Michael Scott 2567b9fb6a net: coap: Fix error handling for coap option length
Currently, we check the length of an option value in the
coap_packet_append_option() function.  This isn't required as
we're appending to a net_pkt and not using struct coap_option
where the limitation is imposed.

Instead, we should check the option value length in
parse_option() where we assign the value to a struct
coap_option.
