Patrik Flykt 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

Andrew Boie ad4df685f1 i2s: add i2s_configure() as a system call
Now that k_mem_slabs are tracked as kernel objects,
even though they have no user facing API, we can now
accept a pointer to one in the configure API.

Andrew Boie 06c23f157f i2s: expose i2s APIs to user mode
User mode may now access the read, write, and trigger APIs.
Unlike supervisor mode, memory slabs are not dealt with directly,
the data is always copied.

A new driver API added to fetch the current channel configuration,
used by the system call handlers.

The i2s_sam_ssc driver updated for the new API. CAVS driver not
modified as there is no user mode port to Xtensa yet.

Anas Nashif 11828bf66b doc: do not show undocumented members
Avoid listing internal function in the public API documentation. After
enabling those doxygen configs, we go lots of errors and bad refs that
were fixed.

David B. Kinder f00f58517b doc: replace UTF-8 chars
Some our Zephyr tools don't like seeing UTF-8 characters, as reported in
issue #4131) so a quick scan and replace for UTF-8 characters in .rst,
.h, and Kconfig files using "file --mime-encoding" (excluding the /ext
folders) finds these files to tweak.
