Whilst time.android.com is NOT used for GPS NTP, North American time servers
are, by specifying north-america.pool.ntp.org as default in the framework,
to align with pixel devices. I am assuming similar response times to these
servers from around the world.
Great for North America and it appears Europe but it does not address the
global issue. Also, the pool.ntp.org project forbids both hardware and
software vendors from using these default zone names.
http://www.pool.ntp.org/en/vendors.html
It makes sense, therefore, to leverage the ntp.org's existing 'android' vendor
name to make the default ntp server for GPS purposes:
1.android.pool.ntp.org this will return a random but accurate NTP server in
close geopraphic proximity to the device.
Testing on my own build in the UK seems to improve hot and cold TTFF
considerably.

Default to false if the property is not set.
Device init scripts will need to be adapted to restart
loc_launcher service when property change is detected.

This fixes enum-conversion warning due to implicit type enum casting
between linked_list and msg_q which happens only for status -6.

-Wreorder-ctor is a compile-time, Clang-only flag which is enabled by
default since Clang 12, which will warn whenever a specified field will
be initialized right after field specified below it. However, since it
doesn't sweep through all fields, compiler may miss some of them.
This order has been checked thoroughly through many trial and errors to
ensure that no such warns will be triggered anymore.
