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

Andy Ross ec554f44d9 kernel: Split reschdule & pend into irq/spin lock versions
Just like with _Swap(), we need two variants of these utilities which
can atomically release a lock and context switch.  The naming shifts
(for byte count reasons) to _reschedule/_pend_curr, and both have an
_irqlock variant which takes the traditional locking.

Just refactoring.  No logic changes.

Andy Ross f4b6daff4b lib/posix: Port wait_q usage to new API
The pthread mutex changes went in with an adaptation to build with the
new wait queue API, but they did it by using the old dlist hooks
directly through typecasting and union assignment.  That... is sort of
the opposite of the intent to having the new API be abstracted.  The
pthread code worked, but failed once wait queues (on x86) stopped
being dlists.

Simple fix once I saw the problem, anyway.

Ramakrishna Pallala f603e603bb lib: posix: Move posix layer from 'kernel' to 'lib'
Move posix layer from 'kernel' to 'lib' folder as it is not
a core kernel feature.

Fixed posix header file dependencies as part of the move and
also removed NEWLIBC related macros from posix headers.
