This PR adds the possibility to specify ZEPHYR_EXTRA_MODULES from an
environmental variable. To add a custom module mymodule in
path/mymodule the variable ZEPHYR_EXTRA_MODULES can be set in
`.zephyrrc` as `export ZEPHYR_EXTRA_MODULES=path/mymodule`.

Moving all thread docs into 1 page was a bit too much. Split the section
a bit and remove redundant and useless sections and move some thread
related documentation from the scheduling page to threads (thread states
and priorities).
Add a new figure for thread states.

Added CONIFG_LOG_BLOCK_IN_THREAD option to block until buffer for
log message is available. When log message is called in the thread
and there is no buffer available in the pool, thread will block with
configurable timeout (CONFIG_LOG_BLOCK_IN_THREAD_TIMEOUT_MS). If
buffer cannot be allocated by that time, message will be dropped.

We don't really have docs on how fatal errors are induced
or handled. Provide some documentation that covers:
- Assertions (runtime and build)
- Kernel panic and oops conditions
- Stack overflows
- Other exceptions
- Exception handling policy

Use globbing to find release notes and display them in the expected
reverse-sorted order (newest release first). Some trickery is needed
because were not using two-digit version/subversion numbers so the list
won't sort naturally. This will eliminate the need to edit the index
page on every release, until we get to subversion 10.

While the two-column layout looked OK in the HTML output, it totally
broke the PDF version of the documentation. So, this change puts the
picture before the text instead of using embedded raw html tags to
create a two-column look. (And fixes the PDF generated output.)

For long lists of items, it's better to use a multi-column display to
make better use of the screen space. We used the hlist directive to
accomplish list, but it has a drawback on small (phone) screens because
under the hood, the rendering is done using tables.
Instead, we can take advantage of built-in CSS multi-column support
available in recent browsers. So, convert uses of the hlist directive
to use an rst-class directive to apply a multi-column class to
the entity. The chosen column-width (18em) gives us a 3-column display
on typical window sizes, but will adjust to more or fewer columns
depending on the actual real estate available.
Also, update the documentation guidelines to mention this change.

System call arguments, at the arch layer, are single words. So
passing wider values requires splitting them into two registers at
call time. This gets even more complicated for values (e.g
k_timeout_t) that may have different sizes depending on configuration.
This patch adds a feature to gen_syscalls.py to detect functions with
wide arguments and automatically generates code to split/unsplit them.
Unfortunately the current scheme of Z_SYSCALL_DECLARE_* macros won't
work with functions like this, because for N arguments (our current
maximum N is 10) there are 2^N possible configurations of argument
widths. So this generates the complete functions for each handler and
wrapper, effectively doing in python what was originally done in the
preprocessor.
Another complexity is that traditional the z_hdlr_*() function for a
system call has taken the raw list of word arguments, which does not
work when some of those arguments must be 64 bit types. So instead of
using a single Z_SYSCALL_HANDLER macro, this splits the job of
z_hdlr_*() into two steps: An automatically-generated unmarshalling
function, z_mrsh_*(), which then calls a user-supplied verification
function z_vrfy_*(). The verification function is typesafe, and is a
simple C function with exactly the same argument and return signature
as the syscall impl function. It is also not responsible for
validating the pointers to the extra parameter array or a wide return
value, that code gets automatically generated.
This commit includes new vrfy/msrh handling for all syscalls invoked
during CI runs. Future commits will port the less testable code.

Instead of
properties:
compatible:
constraint: "foo"
, just have
compatible: "foo"
at the top level of the binding.
For backwards compatibility, the old 'properties: compatible: ...' form
is still accepted for now, and is treated the same as a single-element
'compatible:'.
The old syntax was inspired by dt-schema (though it isn't
dt-schema-compatible), which is in turn a thin wrapper around
json-schema (the idea is to transform .dts files into YAML and then
verify them).
Maybe the idea was to gradually switch the syntax over to dt-schema and
then be able to use unmodified dt-schema bindings, but dt-schema is
really a different kind of tool (a completely standalone linter), and
works very differently from our stuff (see schemas/dt-core.yaml in the
dt-schema repo to get an idea of just how differently).
Better to keep it simple.
This commit also piggybacks some clarifications to the binding template
re. '#cells:'.

A bare 'except:' can do some annoying stuff like eat Ctrl-C (because it

Even better might be to catch some more specific exception, because even
