Squash of the following commits:
gps: Correct forward declaration in proprietary definitions
The qcom prebuilt binary relies on FlpExtLocation_s,
so we cannot change it to FlpExtLocation.
This patch fixes it.
karate: gps: fix remove trailing space
In setXtraUserAgent,
size_t is unsigned and never being negative.
Will cause segmentation fault, if string is all space.
