Kick label encoder out of sdk (#574)
* Temporarily opt-out export.Labels from label encoding stuff

* Stop passing label encoding stuff to export.Labels

* Drop label encoding stuff from SDK

* Dogstatd exporter does not need to implement label exporter anymore

* more dogstatd exporter fixes

* export labels get back to encoding stuff

in a lame way, but improvements are coming in following commits

* Get encoded labels through export.Labels

* make SDK to provide its own implementation of export.Labels

* drop dead code

* add noop label exporter

* make export simple labels immutable

* Move the default label encoder to export package

* Simplify the simple export labels a bit

* Reserve some label exporter IDs

* Document and shuffle the code a bit

* Prepare for bring the iterator benchmark test back

We can install a callback to the Batcher's process function - this is
the place where we can access the labels, and thus test the label
iterator.

* Bring back the iterator benchmarks

* Simplifications and docs

* Fix copyright to be consistent with the rest

* Fix typo

* Put reserved label encoder IDs into constants

We get fewer comments about magic numbers that way.

* Fix the label encoder as label exporter thinko

Replace Ordered with an iterator in export.Labels. (#567)
* Do not expose a slice of labels in export.Record

This is really an inconvenient implementation detail leak - we may
want to store labels in a different way. Replace it with an iterator -
it does not force us to use slice of key values as a storage in the
long run.

* Add Len to LabelIterator

It may come in handy in several situations, where we don't have access
to export.Labels object, but only to the label iterator.

* Use reflect value label iterator for the fixed labels

* add reset operation to iterator

Makes my life easier when writing a benchmark. Might also be an
alternative to cloning the iterator.

* Add benchmarks for iterators

* Add import comment

* Add clone operation to label iterator

* Move iterator tests to a separate package

* Add tests for cloning iterators

* Pass label iterator to export labels

* Use non-addressable array reflect values

By not using the value created by `reflect.New()`, but rather by
`reflect.ValueOf()`, we get a non-addressable array in the value,
which does not infer an allocation cost when getting an element from
the array.

* Drop zero iterator

This can be substituted by a reflect value iterator that goes over a
value with a zero-sized array.

* Add a simple iterator that implements label iterator

In the long run this will completely replace the LabelIterator
interface.

* Replace reflect value iterator with simple iterator

* Pass label storage to new export labels, not label iterator

* Drop label iterator interface, rename storage iterator to label iterator

* Drop clone operation from iterator

It's a leftover from interface times and now it's pointless - the
iterator is a simple struct, so cloning it is a simple copy.

* Drop Reset from label iterator

The sole existence of Reset was actually for benchmarking convenience.
Now we can just copy the iterator cheaply, so a need for Reset is no
more.

* Drop noop iterator tests

* Move back iterator tests to export package

* Eagerly get the reflect value of ordered labels

So we won't get into problems when several goroutines want to iterate
the same labels at the same time. Not sure if this would be a big
deal, since every goroutine would compute the same reflect.Value, but
concurrent write to the same memory is bad anyway. And it doesn't cost
us any extra allocations anyway.

* Replace NewSliceLabelIterator() with a method of LabelSlice

* Add some documentation

* Documentation fixes

91091b44eb Add comments and test for 64-bit field alignment (#418)
* Add comments on needed filed alignment

Add comment about alignment requirements to all struct fields who's
values are passed to 64-bit atomic operations.

Update any struct's field ordering if one or more of those fields has
alignment requirements to support 64-bit atomic operations.

* Add 64-bit alignment tests

Most `struct` that have field alignment requirements are now statically
validated prior to testing. The only `struct`s not validated that have
these requirements are ones defined in tests themselves where multiple
`TestMain` functions would be needed to test them. Given the fields are
already identified with comments specifying the alignment requirements
and they are in the test themselves, this seems like an OK omission.
