fixes#851
This includes all of the associated methods, such as
AsUint64, AsUint64Atomic, AsUint64Ptr, CoerceToUint64, SetUint64
SetUint64Atomic, SwapUint64, SwapUint64Atomic, AddUint64,
AddUint64Atomic, CompamreAndSwapUint64, CompareUint64
Only significant change as a result was converting the histogram
aggregator's `count` state field into an int64 from a `metric.Number`.

Update license header to standard format for source files missed prior.
Add license header to new source files.
Add Makefile check to test all `*.go` and `*.sh` files have a copyright
notice (or comment about them being auto-generated) within the first few
lines.
* 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.

* Initial metrics addition to the OTLP exporter
* Fixes
Update to incorporate merged changes.
Fix lint issues.
* Add sum float64 transform unit test
* Fix static check
* Update comments
Fix malformed License header.
Add documentation for new transform functions.
Remove errant TODO.
* Fix test failures and handle ErrEmptyDataSet
Use `assert.NoError` instead of `assert.Nil` to correctly display
checked errors.
Use the result of `assert.NoError` to guard against `nil` pointer
dereferences.
Add check to skip `Record`s that return an `ErrEmptyDataSet` error and
include test to check this error is correctly returned from the
transform package.
