ctlHandler is passed to RegisterServiceCtrlHandlerEx as a callback

regardless of their type.

Adjust ctlHandler parameters, so they are aligned accordingly.

Also uncomment part of TestExample that verifies passing of
ChangeRequest.Context.

New Context field will be used in the following CL to test

Also adjust TestExample to pass hard coded Context value of 123456

Add basic support for IBM Z (s390x) CPU feature (known as
'facilities') detection.

Note that some of these features are mandatory when using the Go
compiler (for example, ldisp and eimm) but aren't mandatory when
using gccgo.

Cryptographic function detection is not yet implemented for
