Add ErrnoName and SignalName to get errno and signal name strings from
syscall.Errno and syscall.Signal values, respectively.
This repurposes the errors and signals vars (because they are not used
within x/sys/unix currently) and turns them into slices of struct,
containing errno/signal number, name and description. ErrnoName and
SignalName can then be trivially implemented using sort.Search.
Renaming errors to errorList additionaly allows to avoid package aliases
for the errors package.

On Illumos, TestFchmodat fails with:
--- FAIL: TestFchmodat (0.00s)
syscall_unix_test.go:502: Fchmodat: unexpected error: operation not supported on transport endpoint
Like Linux, Illumos doesn't support flags != 0 in Fchmodat, see
https://illumos.org/man/2/chmod
Adjust TestFchmodat accordingly to handle EOPNOTSUPP on Illumos.

Now that Fchmodat is available on all Unices, move TestFchmodat to
syscall_unix_test.go and adjust it such that Fchmodat with
AT_SYMLINK_NOFOLLOW in flags is tested where supported.

All BSDs provide the SYS___GETCWD syscall which can be used to implement
Getwd.
Also add a test based on TestChdirAndGetwd from os/os_test.go

arm64 doesn't have a Dup2 syscall, instead Dup3 is supposed
to be used. Since Dup3 is linux-specific, provide a wrapper
to make writing portable code easier.
Updates golang/go#10235
To verify it, added a testcase for Dup and Dup2.

With these changes the package builds, and the tests pass, using gccgo
on amd64 GNU/Linux. I have not tested other systems but I don't know
why they wouldn't work.

Semi-automatic migration from package syscall to package {plan9,windows,unix}.
No builds attempted yet, but this gets a lot of noise behind us so subsequent
CLs will be more concise and easier to follow.
Subsequent CLs will have semantic content.

This CL copies to each package of go.sys the files from syscall it will need.
Different directories have different files, but these:
mkall.sh
str.go
syscall.go
mksyscall.pl
race.go
race0.go
syscall_test.go
are copied to all three.
No changes yet, these are just copies. They are not ready to use yet:
package names are wrong, for starters. But this clean copy will make
it easier to follow the changes as the packages are enabled.
