Removes very complex boot-time generation of page tables
with a much simpler runtime generation of them at bootup.
For those x86 boards that enable the MMU in the defconfig,
set the number of page pool pages appropriately.
The MMU_RUNTIME_* flags have been removed. They were an
artifact of the old page table generation and did not
correspond to any hardware state.

There's desire to be able to customize parameters on a per-filesystem
basis, which means we need a way to override the Kconfig defaults which
are global. This also means the littlefs data structure cannot own the
cache and lookahead buffers.
Switch to using a macro to define the littlefs data structure. The
default version uses the Kconfig constants. A custom one takes
arguments providing the most likely partition-specific parameters.
Finally the user is free to bypass the helper macros and set any
parameters desired, though validation is limited and only present when
CONFIG_DEBUG is enabled.
Extend the test suite with a performance module, which confirms that
these settings have an impact proportional to the log of changes to the
cache or IO sizes.

Existing file system implementations do not provide the special "."
(current) and ".." (parent) directory entries in the readdir results.
littlefs does.
Remove these entries in the abstraction layer. This simplifies code in
higher level consumers that aren't prepared to see them. Consumers like
FUSE that need them can put them back without having to worry about
conflicts.

This is related to findings in #17997 and changes network related
header files to have include files outside of extern "C" { } block.
Declarations that use C linkage should be placed within extern "C"
so the language linkage is correct when the header is included by
a C++ compiler.
Similarly #include directives should be outside the extern "C" to
ensure the language-specific default linkage is applied to any
declarations provided by the included header.

Previously, context switching on x86 with memory protection
enabled involved walking the page tables, de-configuring all
the partitions in the outgoing thread's memory domain, and
then configuring all the partitions in the incoming thread's
domain, on a global set of page tables.
We now have a much faster design. Each thread has reserved in
its stack object a number of pages to store page directories
and page tables pertaining to the system RAM area. Each
thread also has a toplevel PDPT which is configured to use
the per-thread tables for system RAM, and the global tables
for the rest of the address space.
The result of this is on context switch, at most we just have
to update the CR3 register to the incoming thread's PDPT.
The x86_mmu_api test was making too many assumptions and has
been adjusted to work with the new design.

Currently page tables have to be re-computed in
an expensive operation on context switch. Here we
reserve some room in the page tables such that
we can have per-thread page table data, which will
be much simpler to update on context switch at
the expense of memory.

There are two aspects to this: CPU registers are twice as big, and the
load and store instructions must use the 'd' suffix instead of the 'w'
one. To abstract register differences, we simply use a ulong_t instead
of u32_t given that RISC-V is either ILP32 or LP64. And the relevant
lw/sw instructions are replaced by LR/SR (load/store register) that get
defined as either lw/sw or ld/sd. Finally a few constants to deal with
register offsets are also provided.

With the upcoming riscv64 support, it is best to use "riscv" as the
subdirectory name and common symbols as riscv32 and riscv64 support
code is almost identical. Then later decide whether 32-bit or 64-bit
compilation is wanted.
Redirects for the web documentation are also included.
Then zephyrbot complained about this:
"

LwM2M allows for multiple instance resources such the power source
resources in the device object. These types of resources have
always been very hard to work with, and frankly were poorly
implemented.
This led to other issues where it was very hard to have
non-sequential resource instances, and each resource of this type
needed special getter / setter methods such as:
lwm2m_device_add_pwrsrc()
lwm2m_device_set_pwrsrc_voltage_mv()
Going forward, as more LwM2M objects are implemented this just
doesn't scale well.
To fix this:
- split the resource instance data out from the resource data.
This includes the data pointer information and resource
instance id.
- add resource id and resource instance id to the event callback
functions so user's can see in more detail what resources and
resource instances are being handled.
- allow generic functions like lwm2m_engine_get_*() and
lwm2m_engine_set_*() to access resource instance data.
- adjust object resource initialization macros to map resource
instances to resources at the time of object instance
creation.
- fix up the lwm2m_client as a reflection of all of these changes.

- Several of the functions use "path" as the parameter name for the
string-based LwM2M path. Let's clarify by using "pathstr".

Z_MPOOL_LVLS() expands into the sum of 16 _MPOOL_HAVE_LVL() instances,
and _MPOOL_BITS_SIZE() expands into the sum of 16 Z_MPOOL_LVLS()
instances. In the end, a single _MPOOL_BITS_SIZE() expands to 256
_MPOOL_HAVE_LVL() instances!
Let's make it slightly easier on the compiler, and easier for humans
too, by reworking Z_MPOOL_HAVE_LVL(() so that ic can be used directly
into Z_MPOOL_LBIT_BYTES(), making the code logic much simpler.

The specified order of fields wastes space when the cfb_font_caps enum
isn't packed. Reorder to avoid this behavior.
Also remove the unnecessary array size on the extern symbol declaration,
lest the compiler misinterpret the properties as being zero-length
arrays rather than pointers. (The idiom is already technically
using undefined behavior since we're relying on the linker rather than
the language to produce an array from the individual declarations.)

Add a new DTS/binding parser to scripts/dts/ for generating
generated_dts_board.conf and generated_dts_board_unfixed.h.
The old code is kept to generate some deprecated defines, using the
--deprecated-only flag. It will be removed later.
The new parser is implemented in three files in scripts/dts/:
dtlib.py:
A low-level .dts parsing library. This is similar to devicetree.py in
the old code, but is a general robust DTS parser that doesn't rely on
preprocessing.
edtlib.py (e for extended):
A library built on top of dtlib.py that brings together data from DTS
files and bindings and creates Device instances with all the data for
a device.
gen_defines.py:
A script that uses edtlib.py to generate generated_dts_board.conf and
generated_dts_board_unfixed.h. Corresponds to extract_dts_includes.py
and the files in extract/ in the old code.
testdtlib.py:
Test suite for dtlib.py. Can be run directly as a script.
testedtlib.py (uses test.dts and test-bindings/):
Test suite for edtlib.py. Can be run directly as a script.
The test suites will be run automatically in CI.
The new code turns some things that were warnings (or not checked) in
the old code into errors, like missing properties that are specified
with 'category: required' in the binding for the node.
The code includes lots of documentation and tries to give helpful error
messages instead of Python errors.
