The documentation that describes how Python and pip interact with the OS
when installing packages used to be under a common section, and was
moved to the west bootstrap one later on. Since this information is
required early on (for example on Linux when installing CMake via pip3),
move the info to its own section and link to it from others.

Remove the version numbers from the distribution listings, since those
get outdated quickly and on top of that they are causing confusion due
to those being now too old to contain recent versions of CMake and DTC.

Any fatal error will print "ZEPHYR FATAL ERROR" now, so
we don't have to maintain a set of strings in the

This is now called z_arch_esf_t, conforming to our naming
convention.
This needs to remain a typedef due to how our offset generation
header mechanism works.

We had a function that did this, but it was dead code.
Move to fatal.c and call from z_arm_fatal_error().

We introduce a new z_fatal_print() API and replace all
occurrences of exception handling code to use it.
This routes messages to the logging subsystem if enabled.
Otherwise, messages are sent to printk().

* z_NanoFatalErrorHandler() is now moved to common kernel code
and renamed z_fatal_error(). Arches dump arch-specific info
before calling.
* z_SysFatalErrorHandler() is now moved to common kernel code
and renamed k_sys_fatal_error_handler(). It is now much simpler;
the default policy is simply to lock interrupts and halt the system.
If an implementation of this function returns, then the currently
running thread is aborted.
* New arch-specific APIs introduced:
- z_arch_system_halt() simply powers off or halts the system.
* We now have a standard set of fatal exception reason codes,
namespaced under K_ERR_*
* CONFIG_SIMPLE_FATAL_ERROR_HANDLER deleted
* LOG_PANIC() calls moved to k_sys_fatal_error_handler()

We are standardizing to a arch-independent set of exception
reason codes, don't overload it with internal state of
the ARM fault handling code.

By the latest convention, libc's define struct timespec in
sys/_timespec.h. This is consistent with Newlib and ensures
about errors due to redefinitions.

Per POSIX, open() is defined in <fcntl.h>. fcntl.h in turn comes from
the underlying libc, either newlib, or minimal libc.

That's the header which is supposed to define them, there was even

Unfortunately, Zephyr SDK 0.10.0 ships with outdated Newlib 2.0.0
(from 2015 or earlier) which lacks sys/_timespec.h header, requiring
ugly workaround of defining struct timespec inline (the whole idea
was to standardize on sys/_timespec.h header for different libc's).
This is similar to earlier workaround for struct timeval definition
introduced in a6aee9b4c8. Zephyr SDK ticket for this issue
is https://github.com/zephyrproject-rtos/sdk-ng/issues/64, and it
will ve possible to remove both workarounds when Xtensa toolchain
will be upgraded to newlib version consistent with other
architectures.

POSIX subsys defines struct timespec in <time.h> (as POSIX public
API requires), but newlib defines in in sys/_timespec.h, which
inevitably leads to inclusion order and redifinition conflicts.
Follow newlib way and define it in single place, sys/_timespec.h,
which belongs to libc namespace. Thus, we move current definition
to minimal libc, and will use either minlibc's or newlib's
definition, instead of trying to redefine it.
This is similar to the introduction of sys/_timeval.h done earlier.
Signed-off-by: Paul Sokolovsky <paul.sokolovsky@linaro.org>
Newlib libc already provides sys/stat.h, so trying to have sys/stat.h
on the level of POSIX subsys inevitable leads to include order and
definition conflicts. Instead (as most of other sys/* includes)
should come from the underlying libc.
While moving, made unrelated change of removing #include <kernel.h>,
to accommodate the change reviewers.

This patch tries to avoid memmoves and buffer allocations when there
is enough space in the original buffer. Headers are still contiguous
but not in the same buffer.

This is a rework of the 6lo IPHC uncompression.
The uncompression now tries to work in place on the original buffer
instead of allocation a new one. If there is not enough tail-room,
a new buffer is allocated and filled with the IP and maybe UDP header.
The compressed header is pulled from the original buffer and the
buffer is preserved.

When net_pkt_skip skips the entire data in a net buffer, the cursor
still points to this buffer on data that is off by one.
Calling pkt_cursor_advance in net_pkt_is_contiguous fixes this and
moves the cursor to the next buffer.
