Add support for building the WS2812 LED strip driver sample against
the new ws2812b_sw driver. Currently a configuration is only provided
for the BBC micro:bit board.

This driver uses a bit-banging based technique of generating a signal
for the WS2812B LED strip. Since bit-banging is very timing sensitive,
where each CPU cycle counts, the driver uses inline assembly to
perform the most critical operataions. This initial version of the
driver only supports a Cortex-M0 implementation, and can e.g. be used
with the ZIP Halo LED strip for the BBC microbit:

We're missing a k_sem_give for contexts_lock in the

This fixes a network hang which occurs after any http_close()
call when CONFIG_NET_OFFLOAD is enabled.

This fixes intercompatibility issues with controllers supporting
privacy feature.
Core Spec requires to use network privacy mode as a default when
peer device provides its IRK during bonding when LL Privacy is used,
which is the case for Zephyr. We've seen devices including PTS
which exchanges it's IRK but is not aware about network privacy
mode. This results in Zephyr not able do be reconnect to such bonded
devices.
This workaround sets device privacy mode to be able to reconnect
to such devices.

Logic for sending chunks of data is incompatible with adding
Content-Length: header.
Per https://tools.ietf.org/html/rfc7230#section-3.3.1:
"A sender MUST NOT send a Content-Length header field in any
message that contains a Transfer-Encoding header field."
Going a bit further in my mind: also don't send Transfer-Encoded
chunked data either when the Content-Length header is present.
In general, there will be problems if the http client library
makes payload changes without the user code knowing about it.
This patch removes the use of http_send_chunk() from the new
HTTP client code and instead sends the payload directly to
http_prepare_and_send()
This fixes an issue where every available buffer would be allocated
with repeating payload data because the for loop in http_request()
wasn't ending until we ran out of memory.
NOTE: This patch was previously applied but was lost when
commit d1675bf3e6 ("net: http: Remove the old legacy API")
moved code around.

In commit 9489fa54cc ("net: http: Fix http_prepare_and_send"),
the logic for when to call http_send_flush() was incorrect. This
is causing a call to http_send_flush() every time
http_prepare_and_send() is called.

We should not use the user suppied timeout setting in
http_client_send_req() for the connection timeout. In the
previous API the call to tcp_connect() used
CONFIG_HTTP_CLIENT_NETWORK_TIMEOUT as the timeout setting.
Let's do that here too.
This fixes -ETIMEDOUT error generation when using K_NO_WAIT
for http_client_send_req().

responses without body content.
For the new API, let's add a specific fix for when PUT/POST requests
are responded to with just the status code.

This fixes a bug in the cdc_ecm Ethernet over USB driver. The ECM
spec (section 3.3.1) says that the end of an Ethernet frame is marked
using the USB short packet mechanisim, where the last packet is less
than the maximum packet size. If the Ethernet frame is a multiple of
the USB maximum packet size then a final zero length packet must be
sent.
Linux however sends a one byte packet (usbnet.c:1393) to work
around hardware issues with zero length packets.
The current Zephyr driver works most of the time except when you send
an Ethernet frame of the right length where the last byte is zero,
such as:
$ ping 192.0.2.1 -s 23 -p 0
Zephyr then drops the last byte, creating a short frame which gets
dropped higher up in the stack.

During system initialization, the global static variable (to
mem_domain.c) is initialized with the number of maximum partitions per
domain. This variable is of u8_t type.
Assertions throughout the code will check ranges and test for overflow
by relying on implicit type conversion.
Use an u8_t instead of u32_t to avoid doubts. Also, reorder the
k_mem_partition struct to remove the alignment hole created by reducing
sizeof(num_partitions).

Multiple partitions can be added to a domain, and if they overlap, they
can have different attributes. The previous check would only check for
W^X for individual partitions, and this is insufficient. Overlapping
partitions could have W^X attributes, but in the end, a memory region
would be writable and executable.
The way this is performed is quite "heavyweight", as it is implemented
in a O(n^2) operation. The number of partitions per domain is small on
most devices, so this isn't an issue. CONFIG_EXECUTE_XOR_WRITE is
still an optional feature.
