Jim Mussared 710426024a all: Factor gchelper code to one place and use it for unix & ARM ports.
No functionality change is intended with this commit, it just consolidates
the separate implementations of GC helper code to the lib/utils/ directory
as a general set of helper functions useful for any port.  This reduces
duplication of code, and makes it easier for future ports or embedders to
get the GC implementation correct.

Ports should now link against gchelper_native.c and either gchelper_m0.s or
gchelper_m3.s (currently only Cortex-M is supported but other architectures
can follow), or use the fallback gchelper_generic.c which will work on
x86/x64/ARM.

The gc_helper_get_sp function from gchelper_m3.s is not really GC related
and was only used by cc3200, so it has been moved to that port and renamed
to cortex_m3_get_sp.

# _FORTIFY_SOURCE is a feature in gcc/glibc which is intended to provide extra
# security for detecting buffer overflows. Some distros (Ubuntu at the very least)
# have it enabled by default.
#
# gcc already optimizes some printf calls to call puts and/or putchar. When
# _FORTIFY_SOURCE is enabled and compiling with -O1 or greater, then some
# printf calls will also be optimized to call __printf_chk (in glibc). Any
# printfs which get redirected to __printf_chk are then no longer synchronized
# with printfs that go through mp_printf.
#
# In MicroPython, we don't want to use the runtime library's printf but rather
# go through mp_printf, so that stdout is properly tied into streams, etc.
# This means that we either need to turn off _FORTIFY_SOURCE or provide our
# own implementation of __printf_chk. We've chosen to turn off _FORTIFY_SOURCE.
# It should also be noted that the use of printf in MicroPython is typically
# quite limited anyways (primarily for debug and some error reporting, etc
# in the unix version).
#
# Information about _FORTIFY_SOURCE seems to be rather scarce. The best I could
# find was this: https://securityblog.redhat.com/2014/03/26/fortify-and-you/
# Original patchset was introduced by
# https://gcc.gnu.org/ml/gcc-patches/2004-09/msg02055.html .
