Updates aws/aws-xray-sdk-go#77
Updates evalphobia/logrus_sentry#74
Go 1.12 has updated the behaviour of runtime.FuncForPC so that it
behaves as it did in Go 1.11 and earlier.
This allows errors.Frame to return to a uintptr representing the PC +1
of the caller. This will fix the build breakages of projects that were
tracking HEAD of this package.

Introduces WithMessage as well as errors.fundamental, errors.withMessage
and errors.withStack internal types.
Adjust tests for the new wrapped format when combining fundamental and
wrapped errors.
* Extended stacktrace output
* Make format tests less sensitive to sourcecode prefix
* use testFormatRegexp for all Sprintf tests
* replace output test with sample output
* work around the different fn.Name format in go 1.4
* fix windows tests when there is a drive letter in the source path
* Introduce errors.Stacktrace
Introduce a new type to replace the unnamed return value from
`Stacktrace()`. `Stacktrace` implements `fmt.Formatter` and currently
replicates the default behaviour of printing a `[]Frame`.
In a future PR the values of `%+v` and `%#v` will be extended to
implement a more readable stacktrace.
* Introduce Stacktrace and Frame
This PR is a continuation of a series aimed at exposing the stack trace
information embedded in each error value. The secondary effect is to
deprecated the `Fprintf` helper.
Taking cues from from @chrishines' `stack` package this PR introduces a
new interface `Stacktrace() []Frame` and a `Frame` type, similar in
function to the `runtime.Frame` type (although lacking its iterator
type). Each `Frame` implemnts `fmt.Formatter` allowing it to print
itself.
The older `Location` interface is still supported but also deprecated.
