fix prompt()
The prompt() is useful for supervisor (user) interaction during tests.
However it had numerous problems:
- closed stdin, so second prompt() didn't work
- no editing
- no utf-8 multichar
- unflexible poll interval (poll often to stay responsive to input)
and unrelated:
- stdin was hijacked by subprocess.Popen
Firstly pass stdin=PIPE to all subprocesses to leave the tester's stdin
untouched.
Secondly use python input() to read the user entry (instead of mucking about
with the stdin fd), and import readline for history and editing features.
The old approach was put in place to allow polling DBus and processes
regularly. Instead, allow this by running input() in a separate thread while
polling regularly and slowly in the main thread.
The prompt code is now simpler, cleaner and works better.
Will be used in the upcoming 'debug' suite.
