Summary:
Release notes: https://blog.rust-lang.org/2023/10/05/Rust-1.73.0.html
This release is coupled with an update of the `anyhow` and `thiserror` crates because the unstable standard library API for backtraces has changed.
Fbcode changes:
- `feature(default_free_fn)` deleted (D50300881)
- `noop_method_call` lint becomes warn-by-default (D50486032, D50516201)
- stronger `invalid_reference_casting` detection (D50488164)
- `feature(unix_chown)` has been stabilized
- `feature(provide_any)` and `std::provider` deleted
- `clippy::unwrap_or_else_default` renamed to `clippy::unwrap_or_default`
- type inference ambiguities (D51780425)
- `nu-command` build error (D51779062)

Summary:
anyhow-1.0.73 [uses][1] the new `Error::provide` API. This API is
available starting in Rust 1.73. This means that if you want backtraces,
you need one:
- anyhow-1.0.72 & Rust 1.72
- anyhow-1.0.73 & Rust 1.73
Since we're still on 1.72, pin the version to avoid accidentally losing
backtraces.
There are no real changes between anyhow-1.0.71 and anyhow-1.0.72. But
update to anyhow-1.0.72 so that we're right up until the point where we
get backtrace support.

Summary:
On ARM64 I have been seeing test failures:
```
test vdso::tests::vdso_can_find_symbols_info ... FAILED
test vdso::tests::vdso_patch_info_is_valid ... FAILED
```
Looking closer, this was caused by the debug assertion in vdso_get_symbols_info() which asserts that all symbols found in the VDSO are ELF STT_FUNC symbols. Unfortunately, this is not the case on ARM64, because the VDSO's `__kernel_rt_sigreturn` is special and does appear as STT_NONE symbol.
Fixup the debug assertion by special-casing for this special function.
Note: I shortly considered adding an expected symbol type to the `VDSO_SYMBOLS` hashes, but that didn't seem to make sense just to fix this one special case.

Summary:
The code that is injected into the tracee processes' VDSO needs to be 8 byte aligned in order to satisfy conditions imposed by the ptrace interface on 64 bit architectures. There have been reproducible reports of that not always being the case:
https://github.com/facebookexperimental/hermit/issues/41. Use an explicitly aligned data structure to enforce this.

Summary:
Everything in Reverie is super Linux-specific, so we should just skip compilation if we're not targetting Linux.
This is helpful for consumers of the library when it gets published to crates.io. With this, they don't need to have a special case for this in the `[dependencies]` section of `Cargo.toml`.

```
These implementations just `jmp` to another internal function. The dynamic symbol table reports that these functions are 5 bytes in size, but we can see that they are aligned up to 16 bytes and they are still safe to patch. Thus, our patcher should take this padding and alignment into account.

Summary: The `getcpu` VDSO was just returning 0 unconditionally. This was an old hack to determinize the getcpu syscall, but we don't need this anymore because we just intercept it and determinize it instead. Reducing the size of this vdso function will make it more compatible with various VDSO implementations.
