Add uid field annotation in atoms.proto and statd memory usage optimization.
[memory]
statsd binary size from 664k -> 600k
memory usage 1978k -> 1813k (with no configs)
+ Avoid initialize any static map in statslog.h to avoid many copies of the map in each include.
- Do it in cpp so that it is initialized only in places that use them
[Uid annotation]
+ Uid annotation is needed for extracting uid from dimension for UidCpuPuller.
+ After the change, stand-alone uids don't need to be in field 1 anymore.
+ Also added exclusive bit annotation in AppDied
+ Currently only allow one uid field in an Atom. This is to keep things simple until
we find an exception.
