2dcb527828 Only use Setsid on Unix.
Setsid is not a part of syscall.SysProcAttr on Windows, so we only set that on
systems that have it.

7c84d810d3 Make sure we can delete files on Windows.
Files must be closed on Windows before they can be deleted.
Therefore we keep track of all open files, and closes them before
we delete them.

Also we don't set finished blobs to read-only on Windows, since
that prevents us from deleting them.

5cdcc99eba Use array instead of hash for backend.ID
Since backend.ID is always a slice of constant length, use an array
instead of a slice. Mostly, arrays behave as slices, except that an
array cannot be nil, so use `*backend.ID` insteaf of `backend.ID` in
places where the absence of an ID is possible (e.g. for the Subtree of a
Node, which may not present when the node is a file node).

This change allows to directly use backend.ID as the the key for a map,
so that arbitrary data structures (e.g. a Set implemented as a
map[backend.ID]struct{}) can easily be formed.

1c14be8993 backend: Remove IDSet
This can easily be replaced by a map[{32}byte]struct{}, and this is much
faster.
