Merge pull request #2546 from Summerdave/fix-backup-error-code 
Return an error when errors occured during backup

5729d967f5 backup: Return exit status code 3 when failing to read source data 
The backup command used to return a zero exit code as long as a snapshot
could be created successfully, even if some of the source files could not
be read (in which case the snapshot would contain the rest of the files).

This made it hard for automation/scripts to detect failures/incomplete
backups by looking at the exit code. Restic now returns the following exit
codes for the backup command:

 - 0 when the command was successful
 - 1 when there was a fatal error (no snapshot created)
 - 3 when some source data could not be read (incomplete snapshot created)

7bda28f31f Chaining hash table for repository.Index 
These are faster to construct but slower to access. The allocation rate
is halved, the peak memory usage almost halved compared to standard map.

91906911b0 Fix non-intuitive repository behavior 
- The SaveBlob method now checks for duplicates.
- Moves handling of pending blobs to MasterIndex.
  -> also cleans up pending index entries when they are saved in the index
  -> when using SaveBlob no need to care about index any longer
- Always check for full index and save it when storing packs.
  -> removes the need of an index uploader
  -> also removes the verbose "uploaded intermediate index" messages
- The Flush method now also saves the index
- Fix race condition when checking and saving full/non-finalized indexes

0ce81d88b6 stats: Fix crash in blobs-per-file mode on missing blob 
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.

f17ffa0283 restorer: Allow writing target file blobs out of order 
Much simpler implementation that guarantees each required pack
is downloaded only once (and hence does not need to manage
pack cache). Also improves large file restore performance.
