This handle is already held onto when creating the safe wrapper object,
but is inconsistently required again in some but not all functions.
Remove it from every function and use the internal handle instead.
Closes: #377
Fixes: 05747b2 ("Update Vulkan-Headers to 1.2.162 with stable ray-tracing spec (#341)")
This new version marks `Library::new` as unsafe, because loading a
library invokes the libraries' entrypoint which may or may not have
certain preconditions and perform unsafe/undefined operations, just like
any other native function loaded through `libloading`.
`c_void` is not the same as Rust's void type, `()`, making function
pointers like `PFN_vkFreeFunction` pretty much impossible to implement
without casting. Instead of just turning this into `-> ()`, remove the
return type altogether, and add some asserts to prevent types of this
kind from being accidentally generated.
The `VK_KHR_ray_query` extension has no functions and this safe wrapper
(specifically to re-wrap functions) was added by accident (by me).
To prevent confusion, remove it before a new crate version is released.
Applications can easily access the name (which is the only useful thing
reexported here) from `ash::vk::extensions:KhrRayQueryFn::name()`.
In rust references to DSTs (Dynamically Sized Types) like slices and
trait objects are 16-bytes instead of 8 (leaking into the next parameter
of a function call). The static-sized array generated here has its size
known beforehand and will not suffer from this issue [1], but might be
confusing for future readers/authors: convert it to a raw pointer just
to be safe.

The API for vkCmdTraceRaysKHR mandates a single non-null pointer per SBT
region to a VkStridedDeviceAddressRegionKHR. While providing more than
one such region isn't harmful, passing a slice of length 0 will cause
reads in uninitialized memory and undefined behaviour.
Converting these parameters from slices to references rids the
unnecessary confusion and prevents zero regions from being passed.

ANativeWindow and AHardwareBuffer were [recently changed] to the
basetype category, but without an actual basetype, consequently failing
the Ident constructor with an empty name.
Since these types are already dealt with in platform_types, and there
doesn't seem to be anything sensical to define them to right now, just
ignore these cases.

According to specs for Device Memory (section 10.2), memory types are
topologically sorted by their property flags so the two-pass memory
type selection is unnecessary.

According to specs for vkGetPhysicalDeviceSurfaceFormatsKHR(), at least
one surface format must be returned, and returned formats must not be
VK_FORMAT_UNDEFINED.
This avoids an obnoxious error when attemting to use `dbg!()` while
debugging the generator.
Unfortunately there seems to be no way to import * except `dbg`, or
shadow `dbg` (using eg. `use nom::{dbg as _nom_dbg, *};`).
It is in some cases necessary to load a specific Vulkan dll/so with a
different name and/or from a different location.
Instead of copying this function to a downstream project (and making the
LoadingError constructor public to retain the same interface), split
Entry::new() such that downstream projects can easily specify and use an
alternate Vulkan implementation.
* Deprecate the DebugMarker and DebugReport extension modules
* Allow deprecated modules only in mod.rs, to suppress clippy warning

* Add ash-window as workspace member
* ash-window: fix repository link
* ash-window: Address CI fmt&clippy issues
* ash-window: Try fix SDL2 CI issues
* ash-window: Remove beryllium example
* Allow the generator to be run from project root dir
* Split vk.rs into multiple files
* Breakup and remove generated vk/prelude.rs
Generator changes:
- No longer convert current dir to a string when checking if the
path ends with 'generator'
- Pass the 'ash/src' dir instead of the 'vk.rs' path
Generated and generated output changes:
- The majority of prelude.rs has been moved to macros.rs
- The pointer chain and Handle are now included in vk.rs
- Platform types has been moved to its own file.
