local backend ignore errors in commands inbetween (#2636)
for normal posix shells we have to add the `-e ` option ... but as there
are more shells out there we have to handle this edgecases on base per
base case.

create a switch case statement in woodpecker should be fine as there is
only a finite number of shells, used in production.

also close  #2612

Remove SSH backend (#2635)
The SSH backend is, similar to Gogs and Coding for forges, completely
unmaintained and seems unused (it is likely broken but we didn't get any
reports).
Instead, you should directly run the agent on the SSH machine with the
`local` backend.

Get workflow id from clone steps (#1839)
When in local mode, `getWorkflowIDFromStep` can handle normal steps with
a name like `wp_01h2a6qggwz68zekrkbwqq9rny_0_step_0`.

However, it will fail on clone (unless `skip_clone: true`) with an
`invalid step name` error.

```
invalid step name wp_01h2a2ebppp43bwjdfdsyj1m6m_0_clone
```

This patch handles either `_stage_` or `_clone` as the separator that
the local backend can use to extract the workflowID.

Do not store inactive repos (#1658)
Do not sync repos with forge if the repo is not necessary in DB.

In the DB, only repos that were active once or repos that are currently
active are stored. When trying to enable new repos, the repos list is
fetched from the forge instead and displayed directly. In addition to
this, the forge func `Perm` was removed and is now merged with `Repo`.

Solves a TODO on RepoBatch.

fix: backend auto-detection should be consistent (#1618)
Closes https://github.com/woodpecker-ci/woodpecker/issues/1617

The `woodpecker exec` auto-detects the backend by iterating over a map
of backends. However, since Go 1 the runtime randomizes map iteration
order, so a random backend might be chosen during each execution.

PR changes to auto-detection to iterate over the backends list with
predefined priority: `docker`, `local`, `ssh`, `kubernetes`.

fix: docker backend should not close 'engine.Tail' result (#1616)
Closes https://github.com/woodpecker-ci/woodpecker/issues/1615

The error described in
https://github.com/woodpecker-ci/woodpecker/issues/1615 is happening
because `Tail` method of the docker backend closes the instance of
`io.ReadCloser` it returns in `defer` function. As a result anything
that try to read data returned by `Tail` method eventually will attempt
to read from closes reader and get an error:


2171212c5a/pipeline/backend/docker/docker.go (L229)

The fix is just don't close returned reader and let the consumer of
`Tail` method do it. Good thing is that `Tail` is used only in one place
and reader is correctly closed:


2171212c5a/pipeline/pipeline.go (L231-L237)

Example of `woodpecker exec` output using pipeline from
https://github.com/woodpecker-ci/woodpecker/issues/1615 with the fix:

```
woodpecker exec .woodpecker.yaml
[step1:L0:0s] + echo step1
[step1:L1:0s] step1
[step2:L0:0s] + echo step2
[step2:L1:0s] step2
```

Deduplicate step docker container volumes (#1571)
Try to fix #1495

It's very hard to reproduce it and only way to fix when it gets in this
state is woodpecker agent restart.

This anyway fixes problem if step mounts and
`WOODPECKER_BACKEND_DOCKER_VOLUMES` conflict

Rework status constraint logic for successes (#1515)
Since "success" and "failure" are the only two possible values, and
"success" is considered to be included by default, the existing code can
also be simplified a little.

This has the side effect of ignoring the "exclude" part of the
constraint completely. I put it in the tests just to make sure the
workaround in
https://github.com/woodpecker-ci/woodpecker/issues/1181#issuecomment-1347253585
continues to work as expected, but couldn't think of any legitimate use
cases for it.

Fixes #1181

Fix wrong drone env vars (#1419)
Provide up to date drone compatibility environment variables to each step execution.

closes #1416

Before a step is executed, some environemnt variables are updated.
This ensures, that the updated environment variables are copied to their corresponding `DRONE_` environemt variables.

Side effect is that the `DRONE_` environemnt variables are no longer available in the metadata which should not harm as they are not used inside woodpecker.

add support for DRONE_COMMIT_SHA alias (#1421)
[The docker plugin
uses](d0e7d7f01b/cmd/drone-docker/main.go (L43))
the `DRONE_COMMIT_SHA` variant. According to [drone
reference](https://docs.drone.io/pipeline/environment/reference/) doc,
`DRONE_COMMIT_SHA` and `DRONE_COMMIT` are the same thing (although the
default value in the docker plugin suggests the 8-char short form).

Add option to ignore failures on steps (#1219)
closes #1181
closes #834 

Adds `ignore_failure` to pipeline steps. When it's set to true,
if the step fails the following steps continue to execute as if no failure had occurred.

---

failure enums idea:
* fail (default) = if other steps run in parallel, wait for them and
then let workflow fail
* cancel = if other steps run in parallel, kill them
* ignore = we mark the step as failed but it wont have any impact
