The `dump`, `find`, `forget`, `ls`, `mount`, `restore`, `snapshots`,
`stats` and `tag` commands will now take into account multiple
`--host` and `-H` flags.
With this change it is possible to dump a folder to stdout as a tar. The
It can be used just like the normal dump command:
`./restic dump fa97e6e1 "/data/test/" > test.tar`
Where `/data/test/` is a a folder instead of a file.
Some time ago we changed the paths in the repo to always use a slash for
separation, it seems we missed that the `dump` command still uses the
`filepath` package, so on Windows backslashes are used.
Closes #2079
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.

'dump' writes internal data structes pretty-printed as JSON to stdout.
This was done to debug fsck error messages.
In contrast to the 'cat' command, this one prints the data structures as
there are interpreted by restic, not as they are stored in the
repository. This means that only the merged index from all the index
files is printed out.
This is meant for debugging only, it's compiled only when the "debug"
tag is active.
