Merge pull request #2274 from fgma/master 
Support for Volume Shadow Copy Service (VSS) on windows

5695f9ebd2 vss: Implement VSS support for Windows 
The VSS support works for 32 and 64-bit windows, this includes a check that
the restic version matches the OS architecture as required by VSS. The backup
operation will fail the user has not sufficient permissions to use VSS.

Snapshotting volumes also covers mountpoints but skips UNC paths.

e638b46a13 Embed context into ReaderAt 
The io.Reader interface does not support contexts, such that it is
necessary to embed the context into the backendReaderAt struct. This has
the problem that a reader might suddenly stop working when it's
contained context is canceled. However, this is now problem here as the
reader instances never escape the calling function.

4b0fcaed45 unlock: use proper context for locks cleanup 
The list operation used by RemoveStaleLocks or RemoveAllLocks will
already be canceled by the passed in context. Therefore we can also just
cancel the remove operation as the unlock command won't process all lock
files anyways.

This is no change in behavior as a canceled context did later on cause

repository initialization fail a bit earlier.

88c8e903d2 filter: Fix glob matching on absolute path marker on windows 
A pattern part containing "/" is used to mark a path or a pattern as
absolute. However, on Windows the path separator is "\" such that glob
patterns like "?" could match the marker. The code now explicitly skips
the marker when the pattern does not represent an absolute path.

bcc3bddcf4 filter: only check whether a child path could match when necessary 
When checking excludes there is no need to test whether a child path
could also match the pattern, as it is by definition excluded.
Previously childMayMatch was calculated but then discarded. For simple
absolute paths this can account for half the time spent for checking
pattern matches.

673dda77c0 Less repetitive error messages in internal/cache 
Many instances of errors.Wrap in this package would produce messages
like "Open: open <filename>: no such file or directory"; those now omit
the first "Open:" (or "Stat:", or "MkdirAll"). The function readVersion
now appends its own name to the error message, rather than the function
that failed, to make it easier to spot. Other function names (e.g.,
Load) are already added further up in the call chain.

The archiver first called the Select function for a path before checking

os.FileInfo. Checking first is more obvious and requires less code.

8d0ba55ecd backup: Fix possible deadlock of scanner goroutine 
When the backup is interrupted for some reason while the scanner is
still active this could lead to a deadlock. Interruptions are triggered
by canceling the context object used by both the backup progress UI and
the scanner. It is possible that a context is canceled between the
respective check in the scanner and it calling the `ReportTotal` method
of the UI. The latter method sends a message to the UI goroutine.
However, a canceled context will also stop that goroutine, which can
cause the channel send operation to block indefinitely.

This is resolved by adding a `closed` channel which is closed once the
UI goroutine is stopped and serves as an escape hatch for reported UI
updates.

This change covers not just the ReportTotal method but all potentially
affected methods of the progress UI implementation.

184103647a FindUsedBlobs: merge seen into blobs BlobSet 
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.

c81b122374 rclone: Don't panic after unexpected subprocess exit 
As the connection to the rclone child process is now closed after an
unexpected subprocess exit, later requests will cause the http2
transport to try to reestablish a new connection. As previously this never
should have happened, the connection called panic in that case. This
panic is now replaced with a simple error message, as it no longer
indicates an internal problem.

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

3cd927d180 rclone: Give rclone time to finish before closing stdin pipe 
Calling `Close()` on the rclone backend sometimes failed during test
execution with 'signal: Broken pipe'. The stdio connection closed both
the stdin and stdout file descriptors at the same moment, therefore
giving rclone no chance to properly send any final http2 data frames.

Now the stdin connection to rclone is closed first and will only be
forcefully closed after a timeout. In case rclone exits before the
timeout then the stdio connection will be closed normally.

8554332894 rclone: Close rclone side of stdio_conn pipes 
restic did not notice when the rclone subprocess exited unexpectedly.

restic manually created pipes for stdin and stdout and used these for the
connection to the rclone subprocess. The process creating a pipe gets
file descriptors for the sender and receiver side of a pipe and passes
them on to the subprocess. The expected behavior would be that reads or
writes in the parent process fail / return once the child process dies
as a pipe would now just have a reader or writer but not both.

However, this never happened as restic kept the reader and writer
file descriptors of the pipes. `cmd.StdinPipe` and `cmd.StdoutPipe`
close the subprocess side of pipes once the child process was started
and close the parent process side of pipes once wait has finished. We
can't use these functions as we need access to the raw `os.File` so just
replicate that behavior.
