The PA sync is now "deleted" (i.e. flags reset) before
the terminated callback is called, so that is
possible to create PA sync in the callback. One flag
was already cleared before for this reason, but one
other flag is also required, so we just clear
everything now.

Removed the check for explicit scanning, such that

In 'struct coap_resource' path description:
- the plus symbol represents a single-level wild card in the path;
- the hash symbol represents the multi-level wild card in the path.
This change keeps compatibility with RFC 7252 but allows handling
multiple requests in single function.

The EEPROM API, which was introduced in Zephyr v2.1.0 and has not seen
any changes since, has multiple implementations supporting a wide
variety of EEPROM backends (SPI, I2C, on-chip, simulator).
Bump the EEPROM API from "experimental" to "unstable" according to the
Zephyr API lifecycle process.

Most if not all drivers use an internal function
spi_context_configured() to bypass reconfiguring the SPI peripheral
when nothing has changed. That function determines change based on
comparing the struct spi_config pointer that was last used. This does
not work if a user changes fields within the pointed-to structure.
Document that pointer comparison may be used to detect changes.

The x86 paging code has been rewritten to support another paging mode
and non-identity virtual mappings.
- Paging code now uses an array of paging level characteristics and
walks tables using for loops. This is opposed to having different
functions for every paging level and lots of #ifdefs. The code is
now more concise and adding new paging modes should be trivial.
- We now support 32-bit, PAE, and IA-32e page tables.
- The page tables created by gen_mmu.py are now installed at early
boot. There are no longer separate "flat" page tables. These tables
are mutable at any time.
- The x86_mmu code now has a private header. Many definitions that did
not need to be in public scope have been moved out of mmustructs.h
and either placed in the C file or in the private header.
- Improvements to dumping page table information, with the physical
mapping and flags all shown
- arch_mem_map() implemented
- x86 userspace/memory domain code ported to use the new
infrastructure.
- add logic for physical -> virtual instruction pointer transition,
including cleaning up identity mappings after this takes place.

This produces a set of page tables with system RAM
mapped for read/write/execute access by supervisor
mode, such that it may be installed in the CPU
in the earliest boot stages and mutable at runtime.
These tables optionally support a dual physical/virtual
mapping of RAM to help boot virtual memory systems.

If CONFIG_MMU is active, choose whether to separate text,
rodata, and ram into their own page-aligned regions so that
they have have different MMU permissions applied.
If disabled, all RAM pages will have RWX permission to
supervisor mode, but some memory may be saved due to lack
of page alignment padding between these regions.
This used to always happen. This patch adds the Kconfig,
linker script changes to come in a subsequent patch.

Various API involves functions and data that are conditionally
enabled. Zephyr practice is to exclude data (always) and function
(sometimes) declarations at build time using the enabling preprocessor
macro. This meets functional needs, but blocks generation of the API
documentation as Doxygen will not see the declarations.
Document the need to extend Doxygen's PREDEFINED setting to generate
the documentation.
