71ce8ceb18 kernel: consolidate error handling code

  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()

15a9709186 posix: time.h: Add workaround for outdated newlib used by Xtensa
Unfortunately, Zephyr SDK 0.10.0 ships with outdated Newlib 2.0.0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.

3a4553913e posix: struct timespec: Move definition to sys/_timespec.h
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.

715369350d lib: os: add sys_sem data type
For systems with userspace, the sys_sem exist in user memory working
as counter semaphore for user mode thread. The implemention of sys_sem
is based on k_futex. And the majority of the synchronization operations
are performed in user mode to reduce the calling of system call.
And for systems without userspace enabled, sys_sem behaves like k_sem.

51bc0a065c linker: Make alignment size for sw_isr_table configurable
sw_isr_table has two entries, an argument and an ISR function.  The
comment on struct _isr_table_entry in include/sw_isr_table.h says that
"This allows a table entry to be loaded [...] with one ldmia
instruction, on ARM [...]".  Some arch, e.g. SPARC, also has a double
word load instruction, "ldd", but the instruct must have address align
to double word or 8 bytes.

This commit makes the table alignment configurable.  It allows each
architecture to specify it, if needed.  The default value is 0 for no
alignment.

e51c2095cd linker: move scripts generated code at the beginning of .text
When code relocation enabled, there will be serval regions holding
text. And then there will be function call between these .text
regions, when distance between caller and callee is too far, linker
will automatically generate and insert veneer functions. And these
veneer functions will be located right after the last instruction
in the .text region by the linker. So these code will be put in the
memory reserved for priv_stacks text and kobject text if they don't
consume all the reserved memory. Or the veneer functions will be put
before the reserved memory if there isn't code in the reserved
memory. And then in the user mode building process, there will be
different memory layout and it will cause usr mode not working.
And moving the memory reserved for priv_stacks text and kobject text
at the beginning of .text will avoid above problem. The detailed
analysis for this issue can be found on Github issue #17038.

Fixes: #17038.

765c06376c Revert "sys/util.h: helper macro to perform pointer difference"
This reverts commit 755cc644cc.

This approach is problematic in several ways.  First, `intptr_t` could
cause undefined behavior in the subtraction when the pointer converts to
a negative value.  Except in weird cases where the sign of the pointer
identifies a memory domain (like kernel vs userspace) I'm unaware of any
valid use of `intptr_t`.

Second, this macro was created to address a special need that cannot
rely on defined behavior: i.e. to ensure that data definitions are
placed in contiguous space and access is provided through linker-defined
symbols, for which the language required alignment and continuity is not
guaranteed.

A macro that calculates the span between linker symbols has very
different semantics than one that calculates the difference between
pointers.  Replace the global PTR_DIFF with a documented local macro
that tests what's necessary without risking integer overflow.
