Michael Eischer 5e6af77b7a Unify interactive terminal detection code
Previously the progress bar / status update interval used
stdoutIsTerminal to determine whether it is possible to update the
progress bar or not. However, its implementation differed from the
detection within the backup command which included additional checks to
detect the presence of mintty on Windows. mintty behaves like a terminal
but uses pipes for communication.

This adds stdoutCanUpdateStatus() which calls the same terminal detection
code used by backup. This ensures that all commands consistently switch
between interactive and non-interactive terminal mode.

stdoutIsTerminal() now also returns true whenever stdoutCanUpdateStatus()
does so. This is required to properly handle the special case of mintty.

Michael Eischer 684600cf42 ui: update status for the backup command on non-interactive terminals
Allow the backup command to print status on non-interactive terminals.
The output is disabled by setting a MinUpdatePause == 0.

Michael Eischer 401ef92c5f backup: Fix shutdown hang when running in the background
On shutdown the backup commands waits for the terminal output goroutine
to stop. However while running in the background the goroutine ignored
the canceled context.

greatroar f80b07b2c8 Fix IsProcessBackground on Linux with stdin redirection
The previous implementation assumed that stdin was a terminal.
It now checks the terminal's fd.

Brian Atkinson b8da7b1f4d termstatus: Use io.WriteString to output messages.
The previous implementation was repeating the implementation that is
found inside of io.WriteString. Simplify by making use of the stdlib's
implementation.

Alexander Neumann b2208bb9c2 Rework termstatus
This now keeps the cursor at the first column of the first status line
so that messages printed to stdout or stderr by some other part of the
progarm will still be visible. The message will overwrite the status
lines, but those are easily reprinted on the next status update.
