Parallel to CL 151938 for package x/sys/unix instead of syscall.
iOS needs to use these functions without the "64" postfix.
(The functions do exist, but the App Store bans their use.)

Call into libSystem (Darwin's libc equivalent) to do system calls.
Raw syscalls are not a supported ABI on Darwin, they want us to use
libSystem calls instead.
The stdlib has already been converted to this new regime. This
package is vendored into the stdlib, so we need to fix it also, then
vendor it in again.
Because this package isn't tied to a Go release, we need to keep the
old code around and use the new code only for 1.12 and up.

Port mksyscall.pl Perl script to mksyscall.go.
mkall scripts are modified to run mksyscall.go.
Running ./mkall.sh does not generate any git diff besides
the command name in comments of generated files.

It's only when dest is set to NULL that the OS X implementations of
getxattr() and listxattr() return the current sizes of the named
attributes. An empty byte array is not sufficient. To maintain the same
behaviour as the linux implementation, we wrap around the system calls
and pass in NULL when dest is empty.
The parameters for the OS X implementation of setxattr() vary slightly
compared to the linux system call, specifically the 'position'
parameter:
linux:
int setxattr(
const char *path,
const char *name,
const void *value,
size_t size,
int flags
);
darwin:
int setxattr(
const char *path,
const char *name,
void *value,
size_t size,
u_int32_t position,
int options
);
'position' specifies the offset within the extended attribute. In the
current implementation, only the resource fork extended attribute makes
use of this argument. For all others, position is reserved. We simply
default to setting it to zero. If that's needed by the package user, a
function with a different name needs to be implemented instead.
Similarly for removexattr(), we wrap around and explicitly zero out the
options provided. We do so for interoperability with the linux variant.
If options are needed by the package user, a function with a different
name needs to be implemented instead.

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.

Follow golang.org/cl/50450 and add the Faccessat, Fchmodat, Fchownat,
Linkat, Mkdirat, Openat, Readlinkat, Renameat, Symlinkat and Unlinkat
functions (to conform to POSIX.1-2008) for darwin/arm and darwin/amd64.
Also add the missing AT_* constants.
Generated on Mac OS 10.11 (Darwin 15.6.0). This also regenerates the
syscall numbers for arm and arm64 akin to golang.org/cl/14151
Also fix the mksysnum call in mkall.sh to work for darwin/arm.
