Tobias Klauser 43e60d72a8 unix: unify memory functions on BSD
Make Madvice, Mlock, Mlockall, Mprotect, Msync, Munlock and Munlockall
available equally on all BSD flavors. NetBSD was previously lacking
SYS_MSYNC, so add it.

Reorder the //sys function prototype alphabetically and clean up already
implemented syscalls everywhere.

Also add tests for Mprotect, Msync and Madvice - now that they're
available on all unix platforms.

Fixes golang/go#18513

Tobias Klauser 2d3e384235 unix: add utimensat and use it for UtimesNano on BSD
Follow golang.org/cl/55130 and add the utimensat syscall on *BSD. Use it
in UtimesNano and UtimesNanoAt (which is added on *BSD, akin to the
already existing implementation on Linux and Solaris).

Also add AT_FDCWD and AT_SYMLINK_NOFOLLOW where they are missing. These
might be used with UtimesNanoAt.

In order to be able to generate the syscalls, also add two missing
$GOOS_$GOARCH patterns to mkall.sh. As a side effect, some additional
syscalls are added for openbsd/arm.

Sameer Ajmani aaabbdc969 x/sys/unix: remove the "use" function and its calls.
Update mksyscall*.pl to skip generating calls to "use".
Make build tag handling match what's used in the syscall package.

Ian Lance Taylor 5829c74886 unix: change Dup,Dup2,Dup3 to use Syscall, not RawSyscall
This avoids hanging when a Go program uses a FUSE filesystem and the
dup system call has to close a file descriptor.  When dup uses
RawSyscall then the goroutine calling dup will occupy a scheduler slot
(a p structure) during the call, and may block waiting for some other
goroutine to respond to the close call on the FUSE filesystem.
Changing to Syscall avoids the problem.  This makes Dup a tiny bit
slower but is quite unlikely to make a difference for any real
programs.

Update golang/go#10202.

Rob Pike dc3c21c62b go.sys/unix: use syscall.Errno for errors
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.

Rob Pike 8442dd2c63 go.sys: update package names
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

Rob Pike 20acc5cf31 go.sys: copy files from syscall package to go.sys/{plan9,windows,unix}
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.
