Checking the ToneAlarm under AP_HAL_Linux(BBBMINI is using that) I realize was using old kernek
3.9 device tree, so I updated to 4.X - this will affect only BBBMINI and
Blue boards.
musl implements `sched_*` following the posix standard,
where `sched_setschedule` is used for process scheduling.
Linux implementation defines `sched_*` functions based in
the thread scheduler and not with the process.
Using `pthread_*` should be used to follow such standard.

This can be fixed by using `pthread_setschedparam` and requesting the current
thread id via `pthread_self`.

This allows more channels to be passed to RCInput_UDP protocol while
also allowing less than 8 channels - this is similar to the approach
used by SITL in which the packet size is used to figure out the number
of channels.
- Move macros to functions and improve explanation about logic behind it
- Break code in functions to make it more readable
- Add doxygen comments about functions and how they work in a comprehensive manner
- Improve general code maintainability

Uusally problems evidence themsleves with stdin not working correctly -
for example, "git add -p" skipping through all queries as if the
user was just pressing enter.
The Raspberry Pi 4 uses a new BCM cpu, the BCM2711 with
a peripheral base address of 0xFE000000

Make sure to clear CBAUD before setting the baud and disable
input modifications.
Fix for #12162
This change removes input options that can modify the input data stream.
INLCR: map new line to carriage return
ICRNL: map carriage return to new line
IUCLC: map upper case to lower case
IGNCR: ignore carriage return
BRKINT: send SIGINT on serial break
Using the string template to determine the size of the array to print
into strikes issues as varargs passes the stack variables as integer
types, so the perceived range is larger.
