This change has refactored the illumos layer to make use of the
golang.org/x/sys/unix package to achieve a clean cgo-free solution
for illumos and Solaris.
The approach here should be a template for other systems. I've
also made some changes to the Linux port.
go-sqlmock, which is a dependency for go-colorful tests, have switched from
gopkg.in to Go modules. This repository still records the old gopkg.in import
path in the go.mod file, which confuses `go mod`:
go: gopkg.in/DATA-DOG/go-sqlmock.v1@v1.3.3: go.mod has non-....v1 module path "github.com/DATA-DOG/go-sqlmock" at revision v1.3.3
This commit updates the go.mod file to use the new import path.
