Michael Eischer fbcbd5318c repository: extract LoadTree/SaveTree
The repository has no real idea what a Tree is. So these methods never
belonged there.

Michael Eischer 3d29083e60 copy/find/ls/recover/stats: Memorize snapshot listing before index
These commands filter the snapshots according to some criteria which
essentially requires loading the index before filtering the snapshots.
Thus create a copy of the snapshots list beforehand and use it later on.

Michael Eischer d05c88a5d6 fuse: Properly set uid/gid for directories
In #2584 this was changed to use the uid/gid of the root node. This
would be okay for the top-level directory of a snapshot, however, this
change also applied to normal directories within a snapshot. This
change reverts the problematic part and adds a test that directory
attributes are represented correctly.

Alexander Weiss f8316948d1 Optimize FUSE - make command `restic mount` faster and consume less memory
- Add Open() functionality to dir
- only access index for blobs when file is read
- Implement NodeOpener and put one-time file stuff there
- Add comment about locking as suggested by bazil.org/fuse

=> Thanks at Michael Eischer for suggesting the last two improvements

greatroar 649cbec6c5 Simplify build tags for restic mount
This command can only be built on Darwin, FreeBSD and Linux
(and if we upgrade bazil.org/fuse, only FreeBSD and Linux:
https://github.com/bazil/fuse/issues/224).

Listing the few supported operating systems explicitly here makes
porting restic to new platforms easier.

This does come without xattr/fuse support at this point.

NB: not hooking up the integration tests as restic won't compile without
    cgo with Go < 1.10.

repository/master_index: Optimize Index.Lookup()
When looking up a blob in the master index, with several
indexes present in the master index, a significant amount of time
is spent generating errors for each failed lookup.  However, these
errors are often used to check if a blob is present, but the contents
are not inspected making the overhead of the error not useful.

Instead, change Index.Lookup (and Index.LookupSize) to instead return
a boolean denoting if the blob was found instead of an error.  Also change
all the calls to these functions to handle the new function signature.
