David B. Kinder ec1b1df5ed doc: fix ReST heading underlines
The expected order for heading levels in our ReST documents is # for H1,
* for H2, = for H3, and - for H4.  Some documents snuck in without
following this guideline.

The existing docs immediately dive into the details without providing
the user with any kind of high level overview or description of the

Sebastian Bøe 13a6840261 cmake: Re-organize syscall generation wrt. the build system
This commit fixes
https://github.com/zephyrproject-rtos/zephyr/issues/5008.

It does so by splitting up gen_syscalls.py into two scripts with a
json metadata file to communicate syscall metadata between them. The
parsing script parses header files from include/ and writes syscall
metadata to a file if the contents changed. The generation script
reads from the json file and generates syscall code.

The build system DAG now looks like this:

always_rebuild -> json -> syscalls -> offset.o

The script for generating json will do so only if the content changes,
this ensures that the entire DAG does not always do a full rebuild.

Andrew Boie 2d2a97b3f6 docs: initial user mode documentation
This initial batch of documentation describes policies and
mechanism related to kernel objects and system calls.

Some details on porting user mode to a new arch have been
provided in the architecture porting guide.

Thread documentation updated with some user mode consideration.

This is not the final documentation, more to come in subsequent
patches.
