The key change is to revamp how we parse/store/match a log event, especially how we match repeated field and attribution nodes, and how we construct dimensions and compare them. + We use a integer to encode the field of a log element. And also encode the FieldMatcher into an integer and a bit mask. The log matching becomes 2 integer operations. + Dimension is stored as encoded field and value pair. Checking if 2 dimensions are equal is then becoming checking if the underlying integers are equal. The integers are stored contiguously in memory, so it's much faster than previous tree structure. Start review from FieldValue.h Test: statsd_test + new unit tests Bug: 72659059 Change-Id: Iec8daeacdd3f39ab297c10ab9cd7b710a9c42e86
