Extend device selection to allow selecting a specific transport via
monotonically increasing identifier (visible in devices -l).
This is useful when using multiple devices (like hikey960...) that
have identical bogus serial numbers like 0123456789ABCDEF.

`adb install` was writing success to stderr rather than stdout.
Server mismatch messages were going to stdout rather than stderr.
Error messages should consistently start with a lower case letter.
Also improve consistency of syntax error reporting.

bugreport() will be soon refactored to track progress, which will
require more comprehensive unit tests.
As such, it's better to move it to its own files, which in turn also
requires moving send_shell_command() and usage() to commandline.h.
