875: Add labels to pipelines r=trivial a=kvark
This isn't functional until gfx-hal-0.6 is published, but the API is there.

873: Grand cleanup and refactor of the descriptors in the API r=cwfitzgerald,grovesNL a=kvark
**Connections**
Cleanup follows https://github.com/gfx-rs/wgpu-rs/pull/501Fixes#871Fixes#848
**Description**
There is a lot of small and big things crumbled in here.
The major one is where descriptors live, and how they are parametrized. Logic is the following:
- if something is useful by wgpu-rs's API leave it in `wgpu-types`
- if *in addition* it's useful to `wgpu-native`(i.e. has `repr(C)`), we possibly parametrize it (currently, only label is).
- otherwise, the type is moved to `wgpu-core` and stripped of generics
- remove all the builders
Some medium-sized things:
- moves the subscriber out (#871)
- moves the `RenderCommand` into the `draw` module (which is meant to contain shared things)
- makes `TextureViewDescriptor` fields optional, but receives it directly now (#848)
- moves stencil stuff out into `StencilStateDescriptor`, so that we can derive `Default` for it
- stop accepting raw strings for labels in the `Device` API: neither the clients, or gfx-rs need that shape, and it can't be safe
Some smaller things:
- using NonZeroU8 for anisotropy
- using NonZeroU32 for descriptor count
- putting sampler addressing modes into an array
- add labels to command buffers and pipeline layouts
- improves errors for exceeding binding limits

502: Expose get_bind_group_layout r=grovesNL a=kvark
Returning a new object is fine for BGLs specifically and for these cases in particular because we made sure the refcount is bumped (and BGL has a special kind of refcount) in f164fd1f46

872: Respect texture view aspect on creation r=cwfitzgerald a=kvark
**Connections**
Fixing https://github.com/gfx-rs/wgpu-rs/issues/498 (but needs wgpu-rs update then)
**Description**
We added the aspect field to texture view descriptor but didn't respect it properly.
We do that now, and also disallow Depth-Stencil sampled views
**Testing**
Used the modified water example for testing.

870: Implicit layout r=cwfitzgerald a=kvark
**Connections**
Closes#868
**Description**
The implementation can be split into 3 parts:
1. reflecting the shader for binding expectations, and building a bind entry map from it, merging them between stages. This is only done for shaders that can be reflected, and we error on the rest, for now.
2. based on this info, create new bind group layouts and pipeline layouts. The tricky part here is that we can't generate the ID out of thin air, so we have to pass them into the `create_xx_pipeline` function, which now also returns the number of IDs it consumed, allowing the client to free the rest.
3. API changes in the descriptors, new methods to obtain the bind group layouts from a pipeline
**Testing**
This isn't tested, but I think it's fine: it doesn't affect the old path, and we'll be testing the new path while improving Naga and our reflection anyway.

866: Streghten the multi-ref-count on BGLs r=cwfitzgerald a=kvark
**Connections**
Fixes#834
**Description**
Bind group layouts (BGLs) have to be somewhat uniquely tracked, and there was a synchronization issue with their use of `MultiRefCount`. What would happen in multi-thread environment is that we'd see `bind_group_layout_drop`, which first decreases the refcount, and then adds the ID to the list of suspected resources for deletion. But between these operations, something else may have triggered the triage of suspected resources, and if BGL was already there previously, it would be removed earlier than expected.
The solution I came up with is deferring the "dec()" call until the triage itself. That guarantees no gaps, and in fact it goes in line with the other resources we are tracking. I'm fairly confident that the new method works correctly at all times.
**Testing**
Tested extensively on https://github.com/gfx-rs/wgpu/issues/834#issuecomment-669362572

865: Replace u32 with NonZeroU32 in TextureView r=kvark a=kunalmohan
**Connections**
_Link to the issues addressed by this PR, or dependent PRs in other repositories_
**Description**
_Describe what problem this is solving, and how it's solved._
We now expose separate methods under `Global` to register error/invalid resources. So the check for `mip_level_count = 0` and `array_layer_count = 0` can be made on the client-side in Servo, and directly register an error resource instead of trying to create a real one.
**Testing**
_Explain how this change is tested._
Not yet tested. Will be done wgpu-rs examples.

Non-trivial functional changes would need to be tested through:
- [wgpu-rs](https://github.com/gfx-rs/wgpu-rs) - test the examples.
- [wgpu-native](https://github.com/gfx-rs/wgpu-native/) - check the generated C header for sanity.
Ideally, a PR needs to link to the draft PRs in these projects with relevant modifications.

If you can add a unit/integration test here in `wgpu`, that would be best.

**Description**
Removes the `power.rs` module. If the user wants to detect the battery status and choose between low-power and high-performance, they can do so themselves.

857: Separate valid internal IDs from external ones r=cwfitzgerald a=kvark
**Connections**
Closes#638
wgpu-rs update - https://github.com/gfx-rs/wgpu-rs/pull/494
**Description**
The core change here is to allow user-specified IDs to be in the "Error" state that was introduced in #776 .
This is done by defining an internal `Valid<I>` wrapper. Now, the hub storages can be indexed by this valid wrapper only. For regular IDs, we have to go through `storage.get(index)`, which returns a `Result`. It still panics if the ID is totally garbage though, we don't want to handle what can't be expected here.
All the other changes come mostly as a consequence of that:
- new "Invalid*" error variants are added
- the error types are undergone sever refactoring
- new `command/draw.rs` module for stuff shared between render passes and bundles
- functions to generate error IDs for all the types
- various renames, e.g. `comb` -> `cmd_buf`
The expected use by wgpu-rs is unchanged. So far, I don't think we'd be generating Error IDs, but we can always reconsider.
For browsers though, if `device_create_xxx` failed, they would generate and error ID. It will occupy the slot up until the corresponding JS object is dropped.
**Testing**
Tested on wgpu-rs examples
