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

**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.
See https://github.com/gfx-rs/wgpu/pull/666 for an example.
If you can add a unit/integration test here in `wgpu`, that would be best.

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.

Tested on wgpu-rs examples

853: Implement TEXTURE_COMPRESSION_BC extension r=kvark a=cwfitzgerald
**Connections**
Closes#852.
**Description**
Adds support for BCn textures as specified in the upstream issue. This also shores up the validation and copy logic to work well with the block oriented nature of compressed textures. ETC2 and ASTC should fall out of this easily.
**Testing**
No wgpu-rs changes were needed, however I tested it with the following changes in wgpu-rs: 96c05ef4bf.

845: Finish error model refactor r=kvark a=GabrielMajeri
**Connections**
I think this is the last part of #638. I've reviewed all the remaining `unwrap`s and `assert`s in the code, and these should be the last ones left which ought to return errors (the remaining ones seem to uphold internal invariants).
**Description**
Implements error handling for various conditions, which are then returned to the caller. Including, but not limited to:
- running out of memory when creating a command pool
- running out of memory when creating a frame buffer for a render pass
- invalid dimensions when creating a texture
**Testing**
Tested with core and player.

838: wait for buffer to be done in the player r=cwfitzgerald a=kvark
**Connections**
Fixes our code enough to replay #834 without issues. Doesn't help to solve the original problem though.
**Description**
There are two things in here:
1. don't deduplicate the BGLs if we are not generating new IDs at this layer. This helps Servo/Gecko/player. cc @kunalmohan
2. have an option in `buffer_destroy` to *actually* kill it, at the cost of blocking on GPU sometimes. This is required for the player, since the very next command may try to reuse the ID.

Tested on the trace in #834

832: Return errors from device functions r=kvark a=GabrielMajeri
**Connections**
Part of #638
**Description**
Lots of changes, but they should be easily reviewable commit-by-commit.
- Error types for most of the fallible resource creation errors in `device/mod.rs`
- Removed assertions and replaced them with error types
- All of the `BufferMap`, `BufferNotMapped` etc. errors were united in a single `BufferAccessError`, since it was pretty weird to have so many overlapping error types.
- Removed all `unwrap`s of `gfx-hal` errors - they are now returned to the caller.
**Testing**
Checked with core and tested with `wgpu-rs` (see https://github.com/gfx-rs/wgpu-rs/pull/469)
