Some updates to the reference page for the "core" APIs, and associated
follow-ups in the guides:
- centralize documentation of chosen zephyr nodes in a non-legacy
file, provide a reference to them from the intro page in the guide
- review doxygen docstrings and correct errors for generic APIs
- add introductory text to each section in the API reference
- add missing hardware-specific pages
Documentation for layers built on top of these is mostly left to future
commits, but I do have a smattering of fixes in the guides that I
noticed while I was doing this.

Several reviewers agreed that DT_HAS_NODE_STATUS_OKAY(...) was an
undesirable API for the following reasons:
- it's inconsistent with the rest of the DT_NODE_HAS_FOO names
- DT_NODE_HAS_FOO_BAR_BAZ(node) was agreed upon as a shorthand
for macros which are equivalent to
DT_NODE_HAS_FOO(node) && DT_NODE_HAS_BAR(node) &&
- DT_NODE_HAS_BAZ(node), and DT_HAS_NODE_STATUS_OKAY is an odd duck
- DT_NODE_HAS_STATUS(..., okay) was viewed as more readable anyway
- it is seen as a somewhat aesthetically challenged name
Replace all users with DT_NODE_HAS_STATUS(..., okay), which is
semantically equivalent.
This is mostly done with sed, but a few remaining cases were done by
hand, along with whitespace, docs, and comment changes. These special
cases include the Nordic SOC static assert files.

Add more HOWTO information for the two current devicetree-based device

Usually, we want to operate only on "available" device
nodes ("available" means "status is okay and a matching binding is
found"), but that's not true in all cases.
Sometimes we want to operate on special nodes without matching
bindings, such as those describing memory.
To handle the distinction, change various additional devicetree APIs
making it clear that they operate only on available device nodes,
adjusting gen_defines and devicetree.h implementation details
accordingly:
- emit macros for all existing nodes in gen_defines.py, regardless
of status or matching binding
- rename DT_NUM_INST to DT_NUM_INST_STATUS_OKAY
- rename DT_NODE_HAS_COMPAT to DT_NODE_HAS_COMPAT_STATUS_OKAY
- rename DT_INST_FOREACH to DT_INST_FOREACH_STATUS_OKAY
- rename DT_ANY_INST_ON_BUS to DT_ANY_INST_ON_BUS_STATUS_OKAY
- rewrite DT_HAS_NODE_STATUS_OKAY in terms of a new DT_NODE_HAS_STATUS
- resurrect DT_HAS_NODE in the form of DT_NODE_EXISTS
- remove DT_COMPAT_ON_BUS as a public API
- use the new default_prop_types edtlib parameter

This commit renames the Kconfig `FP_SHARING` symbol to `FPU_SHARING`,

Added support for Qemu User Networking and tested with
qemu_x86 model. The support is kept simple assuming that
the TAP interface will always be preferred for more
sophisticated / practical use cases.
QEMU User Networking is implemented using "slirp", which
provides a full TCP/IP stack within QEMU and uses that
stack to implement a virtual NAT'd network. As this
support is built into QEMU, it can be used with any model
and requires no admin privileges on the host machine,
unlike TAP.
Added documentation to facilitate the user.

The DS3231 is an I2C real-time clock with internal temperature
compensated oscillator, maintaining civil time to 1 s precision with
nominal 2 ppm accuracy from 0-40 Cel.
The basic functionality is exposed as a counter that is always running
at 1 Hz. Much more functionality is exposed as driver-specific API,
including the ability to translate between the time scale of the DS3231
and the time scale of the Zephyr uptime clock. This allows correlation
of events in the system clock to UTC, TAI, or whatever time scale is
used to maintain the DS3231.
