* integer types and timestamp separation
1) unify types to int64. as suggested by beorn. we want to support
counters going down (resets) even if we plan to create new chunks for
now, in that case
2) histogram type doesn't know its own timestamp. include it separately
in appending and iteration

* correction: count and zeroCount to remain unsigned
to make api more resilient and that's what we use in protobuf anyway
