* FixedWingAttitudeControl: rework airspeed scaling
  * move airspeed and scaling calculation into separate method
  * if vtol in hover and airspeed disabled use minimum airspeed instead of trim airspeed

The open flag `U` causes a deprecation warning starting with Python 3.4.
The option to open all kinds of newlines as `\n` has been replaced with
the argument `newline=None`. However, this argument is not available for
Python 2 unless we use `io.open` instead of `open`.

to fix Cygwin upload. It failed silently but when catching it prints
"non-standard baudrates are not supported on this platform".
Discussion about platform independet FTDI detection is in issue #10429.

This uses the systems default shell:
- Ubuntu: dash
- Fedora: bash

Since bash is invoked via /bin/sh, it operates in POSIX mode:
  https://tiswww.case.edu/php/chet/bash/POSIX

- remove '# Ignore the expand_aliases command in zshell.'
  Not needed because the shell operates in POSIX mode
- [[ is bashism -> use [
- autostart_files=( $autostart_file_match )
  is not supported in dash, so use 'ls'
- shellcheck runs the dash flavor, since dash is a minimalistic shell.

Tested on dash & bash.
