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.)
For reference, see fscrypt.h:

When checking the old affinity mask with the fix introduced in CL
137675, the wrong CPU (5 instead of 1) is checked. Correct this and also
move the call to SchedGetaffinity closer to the SchedSetaffinity call in
order to reduce the time window for CPUs to go offline.

This test's existence was predicated upon assumptions about the full
range of known data types and known data into those types. However,
we've learned from Microsoft that there are several undocumented secret
registry types that are in use by various parts of Windows, and we've
learned from inspection that many Microsoft uses of registry types don't
strictly adhere to the recommended value size. It's therefore foolhardy
to make any assumptions about what goes in and out of the registry, and
so this test is meaningless and error-prone.

According to MSDN, "If the data has the REG_SZ, REG_MULTI_SZ or
REG_EXPAND_SZ type, this size includes any terminating null character or
characters unless the data was stored without them. [...] If the data
has the REG_SZ, REG_MULTI_SZ or REG_EXPAND_SZ type, the string may not
have been stored with the proper terminating null characters. Therefore,
even if the function returns ERROR_SUCCESS, the application should
ensure that the string is properly terminated before using it;
otherwise, it may overwrite a buffer."
It's therefore dangerous to pass it off unbounded as we do, and in fact
this led to crashes on real systems.

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.

Chmod toggles the FILE_ATTRIBUTES_READONLY flag depending on the
permission bits. That's a bit odd but I guess some compromises were made
at some point and this is what was chosen to map to a Unix concept that
Windows doesn't really have in the same way. That's fine. However, the
logic used in Chmod was forgotten from Open, which then manifested
itself in various places, most recently, go modules' read-only behavior.
This corresonds with the syscall CL 202439.

ShellExecute is an ancient API with an unusual return signature. It
pretends to return an HINSTANCE for backwards compatibility with Windows
3, but it's actualy a fake HINSTANCE. What's really happening here,
according to MSDN, is that it returns either an Windows error less
than or equal to 32, or it succeeds. So we adjust the return value
accordingly.
Prior to this commit, it was impossible to tell whether this command had
succeeded. For example, when using the "runas" verb, ShellExecute did
not correctly indicate whether or not permission was granted.

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.
