f49cb62812 Backup and restore setuid/setgid/sticky bits 
A user discovered that restic does not restore setuid/setgid/sticky file
attributes. This commit fixes that. The mode is stored in the Go format
as an uint32: https://golang.org/pkg/os/#FileMode

d6935d6625 Fix log message 
'inode' isn't tested, so we don't want to imply that in the debug message.

dfe232cf46 Add Windows node support. 
The syscall.Stat_t doesn't exist on Windows, so it is replaced by an interface,
which Windows can fill out, and field access is replaced by function calls.

Common Unix functionality is put into "node_unix.go", so there is less boilerplate.

Symlinks are skipped on Windows, since they require admin privileges.

55ddd5317d Reduce memory usage for fuse mount 
This changes `repository.LoadBlob()` so that a destination buffer must
be provided, which enables the fuse code to use a buffer from a
`sync.Pool`. In addition, release the buffers when the file is closed.
At the moment, the max memory usage is defined by the max file size that
is read in one go (e.g. with `cat`). It could be further optimized by
implementing a LRU caching scheme.

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.

3e0a97fb13 Fix restore filter 
Internally rename restorer.Filter -> restorer.SelectForRestore to make
semantic clear.

In addition, swap parameters to filepath.Match() so that the pattern can
really be matched.

Limitation: The filter only works on the filename, not on any path
component, e.g. '*.go' selects all go files, 'subdir/foo*' doesn't
select anything.

Fixes #202.
