fix remaining compiler warnings
...
This commit removes all inline annotations that
the compiler does not actually inline, and inserts
pragma directives to selectively disable warnings
where necessary.

arch/at91sam3x8e: fix compile error
...
Enabling CONFIG_CHECK_SYSCALL_SOURCE resulted in a
compile error because the corresponding code block
used an outdated variable name. This commit fixes
the issue.

This is required because the heap is shared among
all tasks and protected using a mutex which only
works in kernel space.

sched: complete rework of context switching
...
The old strategy was to only do context switching
from within the PendSV handler. This worked fine
until now because all syscalls were handled either
atomically or just returned -EAGAIN if the
resource was locked or busy. However, with the
introduction of I/O wait, we need to be able to
sleep directly from within the kernel by moving
the context switching completely into the kernel.

arch: use CMSIS after all
...
It was inevitable, tbh. I really wanted to do
everything entirely from scratch, but all those
hardware registers are just too much to be
maintained by a single person. And since i plan
on supporting different boards at some point in
the future, it would be complete madness to redo
everything for that board.

With my discovery of how to actually use thumb2
