#2610: File permission-related proposals

-------------------------------+--------------------------------------------
Once 6.10 is out of the way, we should file some permission-related
proposals.
`openTempFile` and `openBinaryTempFile` mask the file permissions of the
file they create with 0o600. However, we would like to use it for
implementing things like `writeFileAtomic`, in which case we want the
default file permissions to be used.
`System.Directory` has an internal `copyPermissions` function, but it
should be exported.
This is not the same as `getPermissions s >>= setPermissions d` as the
Permissions type that the latter uses doesn't hold all the permissions
info that we want.
Even better would be to make the Permissions type abstract, so that it
/can/ contain all the info we want. Functions in the unix and Win32
packages would be able to do more with this type than the portable
interface.
