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 aa3c9b7f1e tests/benchmarks: Add scheduler microbenchmark
Useful tool for performance work that removes interaction with other
APIs and thread state.  The best part is that it doesn't rely on timer
interrupt delivery and so works with -icount even on existing qemu
versions and produces deterministic output.
