Catch SIGTERM, run cleanup 
The previous code only ran cleanup (lock release for example) on SIGINT.  For
anyone running restic in a container, the signal is going to be SIGTERM which
means containerized execution would leave locks behind.

While this could be addressed via interposing dumb-init to translate the signal,
a `kill` invocation is going to default to SIGTERM, so the same problem exists
for non container users.

Michael Eischer 306a29980a Print stacktrace in SIGINT handler if RESTIC_DEBUG_STACKTRACE_SIGINT set 
The builtin mechanism to capture a stacktrace in Go is to send a SIGQUIT
to the running process. However, this mechanism is not avaiable on
Windows. Thus, tweak the SIGINT handler to dump a stacktrace if the
environment variable `RESTIC_DEBUG_STACKTRACE_SIGINT` is set.

Michael Eischer e604939e72 Debug log status code if execution is interrupted 
Currently, there is no clear indication in the debug log whether restic
exited or not.

greatroar 7f0aa49f45 cmd/restic: Streamline progress printing 
* PrintProgress no longer does unnecessary Sprintf calls, and performs
  fewer allocations in general
* newProgressMax's callback checks whether the terminal supports
  line updates once instead of once per call
* the callback looks up the terminal width once per call instead of
  twice (on Windows)
* the status shortening now uses the Unicode-aware version from
  internal/ui/termstatus (future-proofing)

Michael Eischer 182655bc88 Replace fmt.Printf/Println/Fprintf with wrapper functions 
cmd/restic/globals.go already provides Printf, Println and Warnf wrapper
which get their output streams from the globalOptions object. This
allows for stream replacements when testing.

Alexander Neumann 2579fe6b7b Ignore SIGPIPE 
Handling SIGPIPE made restic abort when a TCP connection was reset by a
server. This happened on DigitalOcean Spaces, which uses the s3 backend.
