5b96885c6d Control progress rate with RESTIC_PROGRESS_FPS env
Add a RESTIC_PROGRESS_FPS environment variable to limit the interval
at which the progress indicator updates (allowed values: 1-60).

The default rate of 60 FPS can cause high terminal CPU load on some
systems, like iTerm2 on macOS with font anti-aliasing enabled.

Usage:

    RESTIC_PROGRESS_FPS=1 restic ...
    RESTIC_PROGRESS_FPS=60 restic ...

944fc857eb Fix failure to detect some legacy s3 repos
Sometimes s3 listobjects for a directory includes an entry for that
directory. The restic s3 backend doesn't expect that and returns
an error.

Symptom is:
  ReadDir: invalid key name restic/key/, removing prefix
     restic/key/ yielded empty string

I'm not sure when s3 does that; I'm unable to reproduce it myself.

But in any case, it seems correct to ignore that when it happens.

Fixes #1068

9fa4f5eb6b gs: disable resumable uploads
By default, the GCS Go packages have an internal "chunk size" of 8MB,
used for blob uploads.

Media().Do() will buffer a full 8MB from the io.Reader (or less if EOF
is reached) then write that full 8MB to the network all at once.

This behavior does not play nicely with --limit-upload, which only
limits the Reader passed to Media. While the long-term average upload
rate will be correctly limited, the actual network bandwidth will be
very spikey.

e.g., if an 8MB/s connection is limited to 1MB/s, Media().Do() will
spend 8s reading from the rate-limited reader (performing no network
requests), then 1s writing to the network at 8MB/s.

This is bad for network connections hurt by full-speed uploads,
particularly when writing 8MB will take several seconds.

Disable resumable uploads entirely by setting the chunk size to zero.
This causes the io.Reader to be passed further down the request stack,
where there is less (but still some) buffering.

My connection is around 1.5MB/s up, with nominal ~15ms ping times to
8.8.8.8.

Without this change, --limit-upload 1024 results in several seconds of
~200ms ping times (uploading), followed by several seconds of ~15ms ping
times (reading from rate-limited reader). A bandwidth monitor reports
this as several seconds of ~1.5MB/s followed by several seconds of
0.0MB/s.

With this change, --limit-upload 1024 results in ~20ms ping times and
the bandwidth monitor reports a constant ~1MB/s.

I've elected to make this change unconditional of --limit-upload because
the resumable uploads shouldn't be providing much benefit anyways, as
restic already uploads mostly small blobs and already has a retry
mechanism.

--limit-download is not affected by this problem, as Get().Download()
returns the real http.Response.Body without any internal buffering.

042adeb5d0 Refactor credentials management to support multiple mechanisms.
This PR adds the ability of chaining the credentials provider,
such that restic as a tool attempts to honor credentials from
multiple different ways.

Currently supported mechanisms are

 - static (user-provided)
 - IAM profile (only valid inside configured ec2 instances)
 - Standard AWS envs (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY)
 - Standard Minio envs (MINIO_ACCESS_KEY, MINIO_SECRET_KEY)

2133869127 cache: OS-specific cache directories
Windows, and to a lesser extent OS X, don't conform to XDG and have
their own preferred locations for caches.

On Windows, use %LOCALAPPDATA%/restic (i.e., ~/AppData/Local/restic). I
can't find authoritative documentation from Microsoft recommending
specifically which of %APPDATA%, %LOCALAPPDATA%, and %TEMP% should be
used for caches, but %LOCALAPPDATA% is where browsers store their
caches, so it seems like a good fit.

On OS X, use ~/Library/Caches/restic, which is recommended by the Apple
documentation. They do suggest using the application "bundle identifier"
as the base folder name, but restic doesn't have one, so I just used
"restic".

fa0be82da8 gs: allow backend creation without storage.buckets.get
If the service account used with restic does not have the
storage.buckets.get permission (in the "Storage Admin" role), Create
cannot use Get to determine if the bucket is accessible.

Rather than always trying to create the bucket on Get error, gracefully
fall back to assuming the bucket is accessible. If it is, restic init
will complete successfully. If it is not, it will fail on a later call.

Here is what init looks like now in different cases.

Service account without "Storage Admin":

Bucket exists and is accessible (this is the case that didn't work
before):

$ ./restic init -r gs:this-bucket-does-exist:/
enter password for new backend:
enter password again:
created restic backend c02e2edb67 at gs:this-bucket-does-exist:/

Please note that knowledge of your password is required to access
the repository. Losing your password means that your data is
irrecoverably lost.

Bucket exists but is not accessible:

$ ./restic init -r gs:this-bucket-does-exist:/
enter password for new backend:
enter password again:
create key in backend at gs:this-bucket-does-exist:/ failed:
service.Objects.Insert: googleapi: Error 403:
my-service-account@myproject.iam.gserviceaccount.com does not have
storage.objects.create access to object this-bucket-exists/keys/0fa714e695c8ecd58cb467cdeb04d36f3b710f883496a90f23cae0315daf0b93., forbidden

Bucket does not exist:

$ ./restic init -r gs:this-bucket-does-not-exist:/
create backend at gs:this-bucket-does-not-exist:/ failed:
service.Buckets.Insert: googleapi: Error 403:
my-service-account@myproject.iam.gserviceaccount.com does not have storage.buckets.create access to bucket this-bucket-does-not-exist., forbidden

Service account with "Storage Admin":

Bucket exists and is accessible: Same

Bucket exists but is not accessible: Same. Previously this would fail
when Create tried to create the bucket. Now it fails when trying to
create the keys.

Bucket does not exist:

$ ./restic init -r gs:this-bucket-does-not-exist:/
enter password for new backend:
enter password again:
created restic backend c3c48b481d at gs:this-bucket-does-not-exist:/

0bb2a8e0d0 cache: Synchronize downloading

file is accessed again in the future.

fb9729fdb9 sftp: Allow password entry
This was a bit tricky: We start the ssh binary, but we want it to ignore
SIGINT. In contrast, restic itself should process SIGINT and clean up
properly. Before, we used `setsid()` to give the ssh process its own
process group, but that means it cannot prompt the user for a password
because the tty is gone.

So, now we're passing in two functions that ignore SIGINT just before
the ssh process is started and re-install it after start.
