[symbolize] Check modtime on ids.txt This change checks the mod time on the ids.txt file prior to reading the file and thus prior to performing verificiation of the ids.txt. Coupled with caching this reduces the primary cost of the symbolize to be parsing (30-40%, 30% regex alone), lock contention (15%). This represents something like a 1000x speed up. Further optimization seems much harder. Increasing go channel buffer sizes should give a 25%-50% improvement. Change-Id: I0da1a05c7e31afc68d8ddc2eecd0acf42ae59961
