New DC block filter implementation using fixed-point math and guaranteeing
zero DC component on the output signal.

Once the RTC has been synchronized with GPS time, set the gps_set_time
flag back to false. This resets also the corresponding ON/OFF menu entry,
providing both a feedback that the operation is done and allowing the user
to just set it back to ON in case a new synchronization is needed.
Updated isNumberPressed() to make it not return anymore true if star or hash keys are pressed. Check
for character input, star and hash keys included, is now done by the input_isCharPressed function.
This separation also now prevents from entering non numeric characters during VFO frequency input.
Reorganized code for pixel framebuffer in order to have it instantiated once
and for all the possible display drivers. Dropped the display_getFrameBuffer()
function.
Using the newlib's printing functions without floating point support in order
to reduce the overall binary size. This allows to free up around 15kB of space
in the .text section.
Switched to int32_t for RSSI representation to allow running the code also
on devices with limited resources. Defined a new ad-hoc type to still keep
the possibility of using floating points on more capable devices.
Removing 18pt and 24pt fonts from graphics layer since currently are unused
and take up flash space. On MD-380, removal freed up 12'928 bytes in the
.text section.
General code optimization allowing to reduce the overall binary size, especially
for devices without hardware floating point support. On the MD-380 (which has the
FPU) the .text size has been reduced of 4'928 bytes.
GD77 and DM-1801 already have an hardware low-pass filter on the battery measurement
probe which causes the low battery protection to trigger at boot if the digital low
pass filter is also used. Given that the hardware one is good enough for our purposes,
the digital filter is now excluded.
Provides a fix for #221
Add west manifest contributed by edgetriggered to allow automated
cloning of the correst Zephyr revision.
Now codec2 dependency is enabled also for T-TWR build, enabling to build
it from scratch without first building a Miosix target.
Enabled non-cross build to use codec2 compiled sources.
We check if the battery is below minimum and, if so, assume that the charge
is 0%. This to prevent an underflow which would result in the function
returing a 100% charge level.
TODO: the include fixes can be probably refactored by including the
correct zephyr directories, as include/zephyr/posix/pthread.h should
already bringing in those header files.
