Tej Singh 810eeb3eed Mainline logging to statsd: native static libs
Creates an annotation to specify if an atom needs to be logged from a
specific mainline module. Creates options in stats-log-api-gen so that
if the same module name is passed in, cpp/h files will be generated with
only those atoms that are specified. These files can be used to create a
static library per mainline module to log to statsd.

Test: builds
Test: atest stats-log-api-gen-test
Test: does not affect existing shared libstatslog
Test: manually created a static lib for netd and used it to log to
statsd. Used testdrive to validate the data was properly flowing.
