b7eb04b300 x86: consolidate x86_64 architecture, SoC and boards
There are two set of code supporting x86_64: x86_64 using x32 ABI,
and x86 long mode, and this consolidates both into one x86_64
architecture and SoC supporting truly 64-bit mode.

() Removes the x86_64:x32 architecture and SoC, and replaces
   them with the existing x86 long mode arch and SoC.
() Replace qemu_x86_64 with qemu_x86_long as qemu_x86_64.
() Updates samples and tests to remove reference to
   qemu_x86_long.
() Renames CONFIG_X86_LONGMODE to CONFIG_X86_64.

7b981e7372 logging: Fix lack of logging after startup
Commit ad28c2d6 introduced semaphore on which logger thread
pends. It is possible that log messages are created before
any backend is attached. In that case, logger thread pends
on semaphore with pending log messages and is not waken up
unless new log messages comes.

Fixed by setting semaphore when first backend is attached.
This wakes up logger thread and log messages can be processed.

dc7b307a47 logging: Print hexdumps with 16 bytes in one line
The hexdump was earlier printed using 8 bytes in one line like this

[00:00:00.131,143] <wrn> sample_instance.inst2: Example of hexdump:
01 02 03 04 05 06 07 08 |........
09 0a 0b 0c 0d 0e 0f 10 |........
11 12 13 14 15 16 17 18 |........
19 1a 1b 1c 1d 1e 1f 20 |.......
21 22                   |!"

This is not utilizing the width of the output best way possible.

Better utilization of the output is to print 16 bytes in one line
like this:

[00:00:00.131,136] <wrn> sample_instance.inst2: Example of hexdump:
01 02 03 04 05 06 07 08  09 0a 0b 0c 0d 0e 0f 10 |........ ........
11 12 13 14 15 16 17 18  19 1a 1b 1c 1d 1e 1f 20 |........ .......
21 22                                            |!"

In order to make it easier to find / calculate the bytes in the
output, print the output bytes in 8 byte groups.

This has the benefit that it is easier to map the Zephyr hex output
to Wireshark output which prints the bytes like this.

de057ba284 logging: Add log_output flushing to synchronous processing
Even though interrupts are locked before processing in synchronous
call, it is still possible that they will be interrupted by NMI.
In that case log_output module may assert because of buffer
overwritting.

Added flushing of log_output buffer before starting the process to
ensure that output buffer is always in reset state at the beginning.

7e29c9da0b logging: add minimal implementation
The log mechanism, even in immediate mode, adds somewhere
between 1K-2K of footprint to applications that use it.

We want to standardize the logging APIs for all logging
within the kernel, but need to not let platforms with
very constrained RAM/ROM in the dust.

This patch introduces CONFIG_LOG_MINIMAL, which is a very
thin wrapper to printk(). It supports the APIs expressed
in logging/log.h.

This will be the new default for test cases.

892ab4e356 logging: Add basic userspace support
This commit adds basic userspace support to the logging subsystem.
With this change, the following API could be called from user mode:
- LOG_*()
- LOG_INST_*(),
- LOG_HEXDUMP_*(),
- LOG_HEXDUMP_INST_*(),
- LOG_PANIC(), LOG_PROCESS(),
- log_printk(), log_generic(), log_buffrered_cnt(),
- log_filter_set(NULL, ...)

With userspace disabled, the logger behavior and performance
is not affected. With userspace enabled, the calls from kernel
space have an additional overhead introduced by _is_user_context().

The logger behavior changes when it is called from the user context.
All strings logged using LOG_*() and LOG_INST_*() API from userspace
are rendered in place for security reasons and then placed in
log_strdup() memory pool, which should be large enough to hold bursts
of log messages.

subdirectory name and common symbols as riscv32 and riscv64 support
code is almost identical. Then later decide whether 32-bit or 64-bit

Redirects for the web documentation are also included.

"

ec857d0e4a logging: Do not use CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC
On some SoCs the frequency of the system clock is obtained at run time
as the exact configuration of the hardware is not known at compile time.
On such platforms using CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC define
directly introduces timing errors.

This commit replaces CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC by the call
to inline function sys_clock_hw_cycles_per_sec() which always returns
correct frequency of the system clock.

own type, log_arg_t, which now can be adjusted in only one location

width is equivalent to u32_t on 32-bit systems, and u64_t on 64-bit
