2021-05-18[syserror] Add linuxerr package.Zach Koopmans
Add linuxerr package to replace syserror and syserr errors. This is done to improve performance comparing/returning errors to on par with syscall.Errno. The below linuxerr_test (formerly syserror_test) shows linuxerr.Error on par with unix.Error (syscall.Errno) as desired.

2021-03-03[op] Replace syscall package usage with golang.org/x/sys/unix in pkg/.Ayush Ranjan
The syscall package has been deprecated in favor of golang.org/x/sys. Note that syscall is still used in the following places: - pkg/sentry/socket/hostinet/stack.go: some netlink related functionalities are not yet available in golang.org/x/sys. - syscall.Stat_t is still used in some places because os.FileInfo.Sys() still returns it and not unix.Stat_t.

This change also adds extensive testing to the p9 package via mocks. The sanity checks and type checks are moved from the gofer into the core package, where they can be more easily validated. PiperOrigin-RevId: 218296768 Change-Id: I4fc3c326e7bf1e0e140a454cbacbcc6fd617ab55
