2d5ba32f4f Remove Tracer name prefix for Span names (#430)
Spans should not have the Tracer name as a prefix for their names. This
removes the `spanNameWithPrefix` function and instead passes through the
span name unmodified wherever this had been called.

Tests that checked Span names are updated to have the non-prefix
expected names.

d4557c3dfa Refactor current span check (#419)
- Simplify conditionals.
- Remove unnecessary nil check.

Go type assertions return a bool value indicating whether the
assertion succeeded. When the assertion is performed on a nil value,
the bool becomes false without a panic, therefore the nil check is
unnecessary.

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.

9a2484c373 Implement support for NonAbsolute Measurement MaxSumCount (#335)
* Add tests for nonabsolute and varying sign values

* Implement support for NonAbsolute Measurement MaxSumCount

Previously, the MaxSumCount aggregator failed to work correctly with
negative numbers (e.g. MeasureKind Alternate()==true).

* Pass NumberKind to MaxSumCount New() function

Allows it to set the initial state (current.max) to the correct value
based on the NumberKind.

* Revert extraneous local change

* Pass full descriptor to msc New()

This is analagous to the DDSketch New() constructor

* Remember to run make precommit first

* Add tests for empty checkpoint of MaxSumCount aggregator

An empty checkpoint should have Sum() == 0, Count() == 0 and Max()
still equal to the numberKind.Minimum()

* Return ErrEmptyDataSet if no value set by the aggregator

Remove TODO from stdout exporter to ensure that if a maxsumcount or
ddsketch aggregator returns ErrEmptyDataSet from Max(), then the
entire record will be skipped by the exporter.

Added tests to ensure the exporter doesn't send any updates for
EmptyDataSet checkpoints - for both ddsketch and maxsumcount.

* Relayout Aggreggator struct to ensure int64s are 8-byte aligned

On 32-bit architectures, Go only guarantees that primitive
values are aligned to a 4 byte boundary. Atomic operations on 32-bit
machines require 8-byte alignment.

See https://github.com/golang/go/issues/599

* Addressing PR comments

The use of Minimum() for the default uninitialized Maximum value means
that in the unlikely condition that every recorded value for a measure
is equal to the same NumberKind.Minimum(), then the aggregator's Max()
will return ErrEmptyDataSet
