190d8e2f51 Flatten backend.LimitedReadCloser structure 
This inlines the io.LimitedReader into the LimitedReadCloser body to
achieve fewer allocations. Results on linux/amd64:

649cbec6c5 Simplify build tags for restic mount 
This command can only be built on Darwin, FreeBSD and Linux
(and if we upgrade bazil.org/fuse, only FreeBSD and Linux:
https://github.com/bazil/fuse/issues/224).

Listing the few supported operating systems explicitly here makes
porting restic to new platforms easier.

c882a92cd6 backup: Avoid race between password prompt and open repository message

actually prints the message. This may race with the password prompt
printed by `OpenRepository` resulting in a missing prompt.

bdf7ba20cb archiver: Fix race condition triggered by TestArchiverAbortEarlyOnError 
The Save methods of the BlobSaver, FileSaver and TreeSaver return early
on when the archiver is stopped due to an error. For that they select on
both the tomb.Dying() and context.Done() channels, which can lead to a
race condition when the tomb is killed due to an error: The tomb first
closes its Dying channel before canceling all child contexts.
Archiver.SaveDir only aborts its execution once the context was
canceled. When the tomb killing is paused between closing its Dying
channel and canceling the child contexts, this lets the
FileSaver/TreeSaver.Save methods return immediately, however, ScanDir
still reads further files causing the test case to fail.

As a killed tomb always cancels all child contexts and as the Savers
always use a context bound to the tomb, it is sufficient to just use
context.Done() as escape hatch in the Save functions. This fixes the
mismatch between SaveDir and Save.

Adjust the tests to use contexts bound to the tomb for all interactions
with the Savers.

1a1c572bac Fix shutdown hang when restic is started as background job 
restic uses a cleanup hook to ensure that it restores the terminal
configuration to a sane state, when restic is interrupted while reading
a password from the terminal. However, this causes a problem, when
restic runs in a background job, as reconfiguring a terminal will cause
a SIGTTOU to be sent to restic pausing it. Therefore, restic seems to
hang on shutdown when it was running in the background.

This commit changes the behavior to only restore the terminal
configuration if restic was interrupted while reading a password from
the terminal. As reading a password from the terminal requires that
restic is in the foreground, this should avoid restic getting stopped.

Fixes #2298
