The Go "os" package already provides bindings for SEEK_CUR, SEEK_SET and
SEEK_END. Most operating systems also support SEEK_HOLE and SEEK_DATA,
which you can use to skip sparse regions in a file. Let's add bindings,
so we can also do this from within Go.

I just created a couple of virtual machines/QEMU instances containing
stock copies of FreeBSD 12.1-RELEASE. On these systems I ran mkall.sh,
thereby bringing the definitions in sync with that version of FreeBSD.
I also attempted to bring the GOOS=freebsd GOARCH=arm port up to date,
but was unfortunately not able to do so. There doesn't seem to be any
documentation on how to bring this port of FreeBSD up on an emulator.
The only option seems to be to use physical hardware.

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.

Update the generated types and errors for FreeBSD by running mkall.sh
and ensuring no values where removed.

If we use a local type, it won't compare properly with errors from
the rest of the standard library. Errors are the one type from syscall
that propagates through the system, so it's important to have only
one type for them.
Ditto for syscall.Signal.

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.
