[New-bugs-announce] [issue37746] Provide Windows predefined access type constants

[Steve Dower]

New submission from Steve Dower <steve.dower at python.org>:

We currently do not provide the standard access type constants anywhere, despite providing some of the specific access type flags (e.g. in `winreg`):

#define DELETE                           (0x00010000L)
#define READ_CONTROL                     (0x00020000L)
#define WRITE_DAC                        (0x00040000L)
#define WRITE_OWNER                      (0x00080000L)
#define SYNCHRONIZE                      (0x00100000L)

#define STANDARD_RIGHTS_REQUIRED         (0x000F0000L)

#define STANDARD_RIGHTS_READ             (READ_CONTROL)
#define STANDARD_RIGHTS_WRITE            (READ_CONTROL)
#define STANDARD_RIGHTS_EXECUTE          (READ_CONTROL)

#define STANDARD_RIGHTS_ALL              (0x001F0000L)

#define SPECIFIC_RIGHTS_ALL              (0x0000FFFFL)

I'm not sure where the best place to expose them would be. `os` (`nt`) seems best, but it's 99% a POSIX shim that doesn't actually have anything Windows-specific exposed, and `_winapi` is not public.

They're likely already available through pywin32 or similar, but given their use with `winreg` we should probably at least make them available there.
