pactl: add format flag for JSON output
This adds a --format flag to pactl, which can have the values of normal or json.
It also adds JSON output for all the current commands which print output.
This is the first time I've contributed to pulseaudio, and I'm keen to help out and get this change through.
Please let me know what I should do to get it ready.
Thanks. :)
Closes #812 (closed)
Other notes:
I was able to test each command (including its short variant for the list command) except for the message-handlers option, which failed with the following output on my machine:
undefined symbol: pa_context_send_message_to_object, version PULSE_0My distribution's (Arch) pulseaudio also didn't have the message-handlers option either.
