Jim Mussared 1b1b22905e unix: Implement BLE H4 HCI UART for btstack/nimble. 
This commit adds support for using Bluetooth on the unix port via a H4
serial interface (distinct from a USB dongle), with both BTstack and NimBLE
Bluetooth stacks.

Note that MICROPY_PY_BLUETOOTH is now disabled for the coverage variant.
Prior to this commit Bluetooth was anyway not being built on Travis because
libusb was not detected.  But now that bluetooth works in H4 mode it will
be built, and will lead to a large decrease in coverage because Bluetooth
tests cannot be run on Travis.

# _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
