raw-data summed up the size of the blob plaintexts. However, with
compression this makes little sense as the storage size in the
repository is lower due to compression. Thus sum up the actual size each
blob takes in the repository.
The `stats` command checks inodes to not count hardlinked files multiple
times into the restore size. This check applies across all snapshots and
not only within snapshots. As a result the result size was far too low
when calculating it for multiple snapshots and it would vary depending
on the order in which snapshots were listed.
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.
During a backup the index is written before the corresponding snapshots.
To ensure that a concurrent/later restic run can read a snapshot's data,
restic thus must first load the snapshots and only afterwards the index.
Otherwise it is not possible to ensure that the loaded index is recent
enough to cover all of the snapshot's data.
The seen BlobSet always contained a subset of the entries in blobs.
Thus use blobs instead and avoid the memory overhead of the second set.

In a damaged repository with a missing blob, the error message tried to
dereference the subtreeID field of the current node, which is a file
however. Said field is set to nil for a file thus causing a segfault
when dereferenced.
Fix this by using the actual parentTreeID.
The `dump`, `find`, `forget`, `ls`, `mount`, `restore`, `snapshots`,
`stats` and `tag` commands will now take into account multiple
`--host` and `-H` flags.
The help text for `restic stats` lists a number of modes in a list.
Make sure the "more info" text is a separate paragraph rather than
being part of the list.
The default value of the `--host` flag was set to 'H' (the shorthand
version of the flag), this caused the snapshot lookup to fail.
Also add shorthand `-H` for `backup` command.
Closes #2040
