Modified serial_adapter so log are allowed when using USB
CDC ACM serial port emulation.
Added dedicated thread for log processing of the highest application
priority. This allows to transmit all logs without adding k_sleep
anywhere else int the code.
Introduced boot log thread is simpler than the default log threat
which decreases flash footprint by a few dozen bytes.
Added configuration for nrf52840_pca10056 which shows how
to enable looging along with USB - among other, thread log
processing is required.

CONFIG_MULTITHREADING is generally assumed to be y by the zephyr
kernel, even though that's not reflected in the Kconfig. For example,
semaphores depend on it being y, but CMake will still build sem.c even
if it's n.
The sensible default for this option is thus y.
However, it's a size advantage to disable it if the platform drivers
are all aware of this option, such as nRF.
Let's re-work our use of this option to keep it disabled when we know
it's safe, but enable it by default so more platforms can be expected
to work out of the box.

The build overflows by 100B using the 7-2018-q2-update GNU Arm
Embedded toolchain. Turn on size optimizations; this leaves about 19%
of the partition's flash available for MCUboot to grow into.

The removal of CONFIG_BOOT_HAVE_LOGGING in 15aa6ef ("zephyr: remove
BOOT_HAVE_LOGGING Kconfig option") missed some uses. In particular,
the one in mcuboot_config.h that converts Kconfig options to MCUboot's
platform-agnostic configuration macros.
This broke logging even when the relevant Kconfig options were on.
Fix things up by using CONFIG_LOG instead.
Tested logging works again on nrf52840_pca10056. Build tested
nrf51_pca10056 to make sure it still fits. The nrf52840_pca10059 build
overflows flash by 0.16%, but that was a problem before 15aa6ef.

The logger issue on Xtensa is resolved in mainline Zephyr with
239805b2d82aebee4969c3ae57fbf8025c4fb60d. Hence logging can be
enabled now.

Cleaned up the conf file for intel_s1000_crb by defining only
those values that are different from prj.conf.

Disable logging and enable size optimizations on
nrf51_pca10028 target in order to fit in boot slot size
for out-off-the-box build.

The board cannot output logs on the UART because it is used
by MCUBoot's serial recovery for DFU. Remove logging and
the RTT console from project defaults.

The old log subsystem has been deprecated in Zephyr.
Migrate to the new subsystem to avoid compilation warnings.
In-place log processing is selected as it is required as MCUBoot is
one thread application.

The Zephyr CMakeLists.txt uses its own logic to have board-specific
overlays, named boards/${BOARD}.prj. However, the only overlay file we
have, arduino_101.conf, isn't in this boards directory, and this target
doesn't build.
Fix this by moving the target into the right directory. Fixes#188.
