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.

Alexander Weiss 9a9101d144 Support specifying multiple host flags for various commands
The `dump`, `find`, `forget`, `ls`, `mount`, `restore`, `snapshots`,
`stats` and `tag` commands will now take into account multiple
`--host` and `-H` flags.

Jasper Lievisse Adriaanse 96311d1a2b Add support for illumos/Solaris
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.

More optimizations to avoid calling Index.Lookup()

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.
