This implements a file descriptor used for event notification that
behaves like the eventfd in Linux.
The eventfd supports nonblocking operation by setting the EFD_NONBLOCK
flag and semaphore operation by settings the EFD_SEMAPHORE flag.
The major use case for this is when using poll() and the sockets that
you poll are dynamic. When a new socket needs to be added to the poll,
there must be some way to wake the thread and update the pollfds before
calling poll again. One way to solve it is to have a timeout set in the
poll call and only update the pollfds during a timeout but that is not
a very nice solution. By instead including an eventfd in the pollfds,
it is possible to wake the polling thread by simply writing to the
eventfd.

So far, coap_pending structure kept track only of the timeout interval
between two consecutive retransmissions. Calculations inside
`coap_pending_next_to_expire` relied only on this value. This approach
gives incorrect results though, in case multiple messages are pending
for retransmission.
For instance, assuming initial retransmission timeout is set to 2
seconds. If some message had been retransmitted already, its timeout
would be increased to 4 seconds. Any new message added to the pending
list would have a retransmission timeout set to 2 seconds, and will be
returned as a first message to expire, no matter how long the initial
message was already on the list.
To resolve this, add a `t0` field to the coap_pending structure. This
field is initialized to the initial transmission time, and is increased
on each retransmission by the retransmission timeout.
`coap_pending_next_to_expire` uses this value to calculate absolute
time, when the next retransmission should take place, and based on this
information returns correctly first pending message to expire.

This commit renames the Kconfig `FLOAT` symbol to `FPU`, since this
symbol only indicates that the hardware Floating Point Unit (FPU) is
used and does not imply and/or indicate the general availability of
toolchain-level floating point support (i.e. this symbol is not
selected when building for an FPU-less platform that supports floating
point operations through the toolchain-provided software floating point
library).
Moreover, given that the symbol that indicates the availability of FPU
is named `CPU_HAS_FPU`, it only makes sense to use "FPU" in the name of
the symbol that enables the FPU.

This default-y option allows continued use of the legacy devicetree
macros.
There are no functional changes yet, but when this is default n,
old-style DT code won't build. At that point, adding any of these will
be a fix to keep old-style code working:
- "CONFIG_LEGACY_DEVICETREE_MACROS=y" to prj.conf
- "-- -DCONFIG_LEGACY_DEVICETREE_MACROS=y" to the west build command
- "-DCONFIG_LEGACY_DEVICETREE_MACROS=y" to the cmake command
This option can be changed to default n in time for the Zephyr 2.3
release. That will provide users of Zephyr 2.2 with a smooth migration
path to the new devicetree.h API after 2.3 is released, which
nonetheless will alert them immediately that something is wrong due to
build errors.
Unfortunately, __DEPRECATED_MACRO is not sufficient in all cases as a
warning to users. This is because, at least in GCC, macros defined
using __DEPRECATED_MACRO cannot be used in preprocessor lines like
"#if DT_SOME_LEGACY_MACRO".

The previous architecture proved unable to support user expectations,
so the API has been rebuilt from first principles. Backward
compatibility cannot be maintained for this change.
Key changes include:
* Formerly the service-provided transition functions were allowed to
sleep, and the manager took care to not invoke them from ISR
context, instead returning an error if unable to initiate a
transition. In the new architecture transition functions are
required to work regardless of calling context: it is the service's
responsibility to guarantee the transition will proceed even if it
needs to be transferred to a thread. This eliminates state machine
complexities related to calling context.
* Constants identifying the visible state of the manager are exposed
to clients through both notification callbacks and a new monitor API
that allows clients to be notified of all state changes.
* Formerly the release operation was async, and would be delayed for the
last release to ensure a client would exist to be notified of any
failures. It is now synchronous.
* Formerly the cancel operation would fail on the last client associated
with a transition. The cancel operation is now synchronous.
* A helper function is provided to safely synchronously release a
request regardless of whether it has completed or is in progress,
satisfying the use case underlying #22974.
* The user-data parameter to asynchronous notification callbacks has
been removed as user data can be retrieved from the CONTAINER_OF
the client data.

This operation is formally defined as rounding down a potential
stack pointer value to meet CPU and ABI requirments.
This was previously defined ad-hoc as STACK_ROUND_DOWN().
A new architecture constant ARCH_STACK_PTR_ALIGN is added.
Z_STACK_PTR_ALIGN() is defined in terms of it. This used to
be inconsistently specified as STACK_ALIGN or STACK_PTR_ALIGN;
in the latter case, STACK_ALIGN meant something else, typically
a required alignment for the base of a stack buffer.

Bug fix and improved `payload` handling in `http_client_req`.
Changes to `http_client_req` behaviour:
If the user provides `payload_len` it is used to generate the
`Content-Length` header. This is done even if `payload_cb` is used to
provide the actual data. If no `payload_len` is specified then no
`Content-Length` is generated.
If `payload_cb` is provided it is called to send the payload data.
Otherwise `payload` is used as the payload buffer and sent. If
`payload_len` is not zero, it is used as the size of `payload`.
Otherwise `payload` is assumed to be a string and `strlen` is used to
determine its size. This is to maintain current behaviour and not break
existing samples.

Zephyr being an OS is typically expected to run at EL1. Arm core
can reset to EL3 which typically requires a firmware to run at EL3
and drop control to lower EL. In that case EL3 init is done by the
firmware allowing the lower EL software to have necessary control.
If Zephyr is entered at EL3 and it is desired to run at EL1, which
is indicated by 'CONFIG_SWITCH_TO_EL1', then Zephyr is responsible
for doing required EL3 initializations to allow lower EL necessary
control.
The entry sequence is modified to have control flow under single
'switch_el'.
Provisions added by giving weak funcions to do platform specific
init from EL3.
