TestFstatat occasionally fails on some builders due to mismatching
Stat_t info returned by the calls to Fstatat (most likely due to Atime
changing). Fix the test by just comparing some well known members.

For linux and *bsd, implement func fcntl in fcntl.go instead of
generating it. Implement it using fcntl64Syscall, so SYS_FCNTL64 is used
on 32-bit linux.
For aix, darwin and solaris continue generate func fcntl as before.

CL 204418 adds functions PtraceGetRegSetArm64 and PtraceSetRegSetArm64 to file
zptrace_armnn_linux.go, both of which depend on type Iovec. The definitions of type
Iovec on linux arm and arm64 are different, but file zptrace_armnn_linux.go is
shared by them. So these two functions cause compilation errors on linux arm. This
patch fixes this error by moving these two functions into a separate file.

Since arm64 GNU/Linux version 2.6.34, PTRACE_GETREGS was replaced by PTRACE_GETREGSET,
in order to get or set the general purpose and floating-point register values,
PTRACE_GETREGSET/PTRACE_SETREGSET request type and a proper "NT_XXX" constant values
should be used. For the sake of not breaking the existing API, we added two functions
PtraceGetRegSetArm64 and PtraceSetRegSetArm64, they take an additional argument "addr",
and use PTRACE_GETREGSET and PTRACE_SETREGSET request types respectively.

Create Go bindings for the updated fscrypt UAPI from Linux v5.4:
- Various new ioctls. We use the regex FS_IOC_.*ENCRYPTION to match
both the new and existing fscrypt ioctls.
- Various new structures for passing to the ioctls
- Various new constants named like FSCRYPT_*
- FscryptPolicy was renamed to FscryptPolicyV1. (But the old name is
still available for source compatibility.)
- The existing fscrypt-related constants named like FS_* (besides the
ioctls) were renamed to FSCRYPT_*. (But the old names are still
available for source compatibility.)

move the call to SchedGetaffinity closer to the SchedSetaffinity call in
order to reduce the time window for CPUs to go offline.

While the other BSDs use __sysctl as the name, Darwin now uses sysctl,
without the leading underscores, and considers __sysctl to be "private".
Using __sysctl leads to App Store rejections, and Go's syscall package
already uses the proper syscall. So this commit changes Darwin's syscall
to use it too here, while reverting a recent commit that removed it all
together on arm and arm64.
This reverts CL 194097.

Getdirentries is implemented with the __getdirentries64 function
in libSystem.dylib on darwin/{386,amd64}. That function can't be used in
an app store application.
Implement Getdirentries using the underlying
fdopendir/readdir_r/closedir for Go 1.13. The simulation isn't faithful,
and could be slow, but it should handle common cases.
For Go 1.12, fall back to raw syscalls since syscall.syscallPtr needed
to use fdopendir from libSystem.dylib is not available.
Follow CL 168479 and CL 170892 which did the same for syscall in the
stdlib.
Tested on darwin/amd64 with Go 1.11, Go 1.12 and Go 1.13
