Exit bad as it fails to open a board, so that we don't just rely on the
client to read this message and close the link.

In some cases as the client is disconnected a SIGPIPE is delivered to
bad, trap this and power off the board.

When using cdba to bisect for intermittent issues related to boot
lockups or crashes taking us to download mode it's only useful to
power-cycle on success (as a failure case shows the intermittent
problem).
Add a special version of the existing power cycle code, that stops the
power cycling loop if a timeout criteria is hit, cutting down on
unnecessary reboots of a broken kernel.

Specifying -t means that inactivity timeout should be disabled,
regardless of the value. Specifying either -t 0 or -T 0 will set timeout
to 0, which means no timeout, regardless of timeout_on_inactivity.

Reverse the logic of inactivity timeout so that by default we set
inactivity timeout to 600s. Passing -T 0 disables inactivity timeout
completely.

If conmux goes away, e.g. by someone invoking ~$quit, the read() from
the conmux fd will continously return 0, which is not discarded as an
error, but sent as a console output message to the client, continuously.
Quit bad when this happens, instead.

When pointing alpaca to persistent named aliases in /dev/serial/by-id we
end up with > 80 chars of path in value, which gets nicely truncated.
Increase this max.

In addition to have a fixed timeout (-t) introduce a new inactivity
timeout (-T) which allow us to provide a shorter timeout to quickly
abort when the kernel fails to boot but still allow us to run lengthy
test scripts without getting a timeout.

Make the exit code non-zero when the cdba for some reason failed, to
allow tools calling cdba to differentiate the various scenarios.
There is still some tuning needed here, but for now we exit with error
code 110 if we reached a timeout, 1 if there was an error and 0 if we
either exited by user request or by hitting the power-off token.

In the event that cdba is launched from e.g. a cron job stdin won't be a
tty and as such we can't modify the termios settings.

There are other users than myself of this, so don't hard code the conmux
id as "bjorn" but rather base it on $USER.

There are cases where fastboot simply disconnects, where it makes sense
to maintain the cdba connection, so return gracefully from
fastboot_download() when this happens.

When a conmux is already attached the motd becomes quite long,
surpassing the 128 bytes, bump the max response length.
This solves the problem sometimes seen as:
bad: parsing reqistry lookup response: truncated percent-encoding

For some devices it's not possible to use fastboot boot and
as such they will not enter fastboot unless the fastboot key
is held. Expose this functionality in the device api.
