PowerPreference::Default will now prefer discrete GPUs
when on AC power and will prefer integrated GPUs while
on battery power (i.e. the battery is discharging).
418: Hotfix deadlocks on resource cleanup r=kvark a=LaylConway
This resolves resource cleanup causing deadlocks with `maintain`, because of `Device::pending` being locked in reverse order.
I'm calling this a "hotfix" because I don't think this is a scaleable approach to resolve how the issue happened in the first place, but it alleviates current deadlocking isssues.
I'm not quite sure how `Token` works, so I don't know if I used that right here.
This fixes#417

412: Another big tracking refactor r=later a=kvark
Fixes#409
Note: there is way more code that had to be thrown out in the process of this PR than there is in the PR itself.
Also fixes [this comment](04e17b3f4f/wgpu-core/src/track/texture.rs (L29)):
> //TODO: make this less awkward!
## Logic
Instead of having a run-time per-operation control over what state is being used for stitching (with `Stitch` enum), we are now deriving this automatically on a per-subresource level. Whenever we are detecting a transition for a sub-resource, and we know there wasn't any "first" state associated with it in the current tracker, we are saving this "first" state. Unlike previous code, where it was confusing what of `Unit` fields (`init`, `last`) are valid, now `first` is `Option<>`, so we know we should be using it if it's there.
This allows us to have this hybrid tracking state of a render pass, where all resources are immutable (and their usage is extended), except for the output attachments. This, together with a whole lot of refactoring, gets us #409.
I'm actually quite happy with the tracking code now. It's finally taking shape we aren't afraid to tell others about :)
Note: this was tested on wgpu-rs examples and vange-rs.

416: Makefile package command and travis github releases r=kvark a=Korijn
Closes#414
Approach mostly mimicked from [gfx-portability](https://github.com/gfx-rs/portability) as recommended to me by @kvark. I needed a number of commits to iron out some kinks for the Windows builds, so I would recommend using squash merge when accepting this PR.
Note that the Windows rust=nightly build fails, but it's also broken on master, so it's unrelated to the changes in this PR.

# Questions
- [x] Would it make sense to also regenerate the `ffi/wgpu.h` and `wgpu-remote.h` header files and include them in the zip archive?
# Todo for maintainers
- [x] Configure encrypted `api_key`
As in [gfx-portability](https://github.com/gfx-rs/portability/blob/master/.travis.yml#L61) you will need to create an API key and commit it to the `.travis.yml` file. I've checked "allow edits from maintainers" so you should be able to commit to this branch directly. You may want to reference the [Travis instructions](https://docs.travis-ci.com/user/deployment/releases/#authenticating-with-an-oauth-token) as well.
- [ ] Tag revisions
Previous versions (`v0.1` - `v0.4`) have not been tagged on the master branch, you will want to do so retroactively. Also, when releasing in the future, make sure to tag the commit before pushing. Alternatively, you can schedule a travis build manually after applying the tag retroactively.

Fixes#419
424: swapchain creation: check if selected present mode is supported r=kvark a=Veykril
Implements a simple check as talked about in #350 to fallback to `FIFO` should the selected present mode not be available on the system.

To make later bind group layout compatibility checks simpler (and
cheaper), deduplicate them on creation. If two bind group layouts with
same descriptors are requested, only one is created and the same id is
returned for both.
387: Stop dynamic offset iteration when the bind groups stop r=grovesNL a=kvark
Fixes#386
I imagine the code is not performance-optimal and could be improved. This PR focuses on correctness.
