172b209f2d sched/assert: Re-implement assert() into user space
_assert is a kernel procedure, entered via system call to make the core
dump in privileged mode.

Running exit() from this context is not OK as it runs the registered
exit functions and flushes streams, which must not be done
from privileged mode as it is a security hole.

Thus, implement assert() into user space (again) and remove the exit()
call from the kernel procedure.

since the new location is more reasonable

d6827cab60 arch: up_assert shouldn't call exit directly
since exit will be only callable from userspace and change
the 1st argument from "const uint8_t *" to "const char *"
