It had been noticed that sometimes the Android emulator in our CI took
several minutes to fully boot. It turns out that this behavior can be
reproduced locally by removing the image files under $HOME/.android
especially the "userdata-qemu.img.qcow2" file.
Then the emulator goes through several reboots until fully booted with a
full set of packages installed. We discovered that the property that
signifies it is finished is dev.bootcomplete=1. So we now check for this
flag and remove the other heuristics we had.
We also disable the debug output to avoid hundreds lines of
logs. Instead we selectively print the values that the emulator returns,
every second until full boot is detected.
We increase the Coin timeout for the shell script, from 5min to 10min,
since it has been measured that it takes about 2.5min on a good day, and
the script itself retries several times to restart the emulator in case
of failure.
Finally we adjust the coding style a bit to be more consistent.
