ffbd48e2c1 logging: Fix false strdup buffer freeing
Algorithm for freeing strdup buffers was only checking if argument
matches address within strdup buffer pool and was attempting freeing
even if format specifier was different than string.

Added fix where also format specifier is checked.

Extended logger test to verify correctness of function which searches
for string format specifiers within a string.

08a017a34b logging: Fix synchronous logging in thread context
Due to flipped logic is_irq_locked function was returning true then
interrupts were unlocked. Because of that CONFIG_LOG_BLOCK_IN_THREAD
feature was not working correctly and wasn't locking thread context
when log message buffer pool was empty.

4f77c2ad53 kernel: rename z_arch_ to arch_
Promote the private z_arch_* namespace, which specifies
the interface between the core kernel and the
architecture code, to a new top-level namespace named
arch_*.

This allows our documentation generation to create
online documentation for this set of interfaces,
and this set of interfaces is worth treating in a
more formal way anyway.

cc5094b3bf logging: Add option to block in thread context
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.

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.

6987937582 log facility: make its records 64-bit compatible
Log records may store either data or pointers to more records. In both
cases they must have the same size. With 64-bit pointers, the amount
of data that can occupy the same space as a pointer has to be adjusted.
And storage alignment has to accommodate actual pointers not u32_t.

0567f161d8 log facility: make its arguments 64-bit compatible
Log arguments were hardcoded to u32_t values. On 64-bit systems, this
is rather restrictive. To make things clear, arguments now have their
own type, log_arg_t, which now can be adjusted in only one location
if need be.  It is currently defined as unsigned long whose effective
width is equivalent to u32_t on 32-bit systems, and u64_t on 64-bit
systems.

4344e27c26 all: Update reserved function names
Update reserved function names starting with one underscore, replacing
them as follows:
   '_k_' with 'z_'
   '_K_' with 'Z_'
   '_handler_' with 'z_handl_'
   '_Cstart' with 'z_cstart'
   '_Swap' with 'z_swap'

This renaming is done on both global and those static function names
in kernel/include and include/. Other static function names in kernel/
are renamed by removing the leading underscore. Other function names
not starting with any prefix listed above are renamed starting with
a 'z_' or 'Z_' prefix.

Function names starting with two or three leading underscores are not
automatcally renamed since these names will collide with the variants
with two or three leading underscores.

Various generator scripts have also been updated as well as perf,
linker and usb files. These are
   drivers/serial/uart_handlers.c
   include/linker/kobject-text.ld
   kernel/include/syscall_handler.h
   scripts/gen_kobject_list.py
   scripts/gen_syscall_header.py

75f77db432 include: misc: util.h: Rename min/max to MIN/MAX
There are issues using lowercase min and max macros when compiling a C++
application with a third-party toolchain such as GNU ARM Embedded when
using some STL headers i.e. <chrono>.

This is because there are actual C++ functions called min and max
defined in some of the STL headers and these macros interfere with them.
By changing the macros to UPPERCASE, which is consistent with almost all
other pre-processor macros this naming conflict is avoided.

All files that use these macros have been updated.

messages consisting of more than 2 chunks had to be added. So far
messages could consist of one chunk (up to 3 args) or two chunks
(2 args in first chunk and 7 in second chunk). Once 2+ chunks
support is added number of arguments is techinically limited to
15 (4 bit field). log_core and log_output extended to suppor 10

Log API can be used before user can explicitly initialize the logger.
In order to ensure that logger core is ready to buffer log messages
it must be initialize as early as possible. Initialization does not
include initialization of default backend since driver may not be
ready and backend is needed only when log messages are processed.
