Update meson and cmake config to only include openrtx and platform paths.
Update files to use <..> for system and external libraries, ".." for
project files and new relative paths as necessary.
Did not attempt to fix areas where includes that should be <..> were
previously ".."
Inspired by #96, closes#359.

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.
Given that each radio driver loads its calibration data when initializing
and that the radio driver is strongly platform-specific, there is no strong
need for an intermediate redirection layer through the platform API.
