Testing response times to time.android.com from around the globe reveals
in ms:-
Europe <30
Middle East <68
North America <150
Johannesburg 183
Buenos Aires 220
Tokyo 226
Sydney 276
Hong Kong 285
Brisbane 295
Mumbai 349
Beijing 4691
Shanghai 4906

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.

Do not set SV in use mask based on intermediate
position update from modem since it might contain
stale information. Reset the flag indicating SV
are used in fix for intermediate fixes.

This CL replaces all LOCAL_MODULE_PATH_* definitions for vendor shared
libraries with LOCAL_VENDOR_MODULE := true instead. This appropriately
generates sanitized versions of these libraries to /data/asan/* while
generating the stock versions in /vendor/lib* as desired.
Needed for ASAN builds to work correctly.

$ANDROID_PRODUCT_OUT/vendor/lib* do not contain asan symbols, while
the ones in $ANDROID_PRODUCT_OUT/data/asan/vendor/lib* do.
