- One has to think about lifetimes if a type has one:
- `<&'a Node<'tree>>::language` now returns `LanguageRef<'tree>` instead of
`LanguageRef<'a>`, as it should;
- Remove explicit "outlives" requirements from `QueryMatches`, `QueryCaptures`,
and their impl blocks, because they're inferred
- Removed unnecessary `&mut` from `cst_render_node`'s `cursor` parameter
System endian conversion macros are gated behind this feature flag for
older versions of GLIBC. `_BSD_SOURCE` and `_SVID_SOURCE` were
deprecated and replaced with `_DEFAULT_SOURCE` starting with GLIBC 2.19.
Instead of returning an undocumented boolean flag, use a
core::ops::ControlFlow object. At the expense of being a bit more
verbose, this is a type that should be self-explanatory in the context
of a callback, as an indication of whether to continue processing or
stop.
Problem: When using alternations, the `#eq?` predicate does not always use the same capture name.
Solution: Iterate the left and right captured nodes more independently.
**Problem:** When encountering an invalid symbol at the beginning of the
file, the rust bindings attempt to index the character at position -1 of
the query source, which leads to an overflow and thus invalid character
index which causes a panic.
**Solution:** Bounds check the offset before performing the subtraction.
Since cargo 1.63, $CARGO_PKG_RUST_VERSION is set in the build
environment to the value of the rust-version Cargo.toml field.
This removes the need to manually invoke cargo from build.rs during a
build of the tree-sitter crate with the bindgen feature enabled.
Removing the cargo invocation also ensures the build doesn't write to
the current directory when the target directory has been redirected
elsewhere. "cargo metadata" will attempt to update Cargo.lock, which
will fail if the source tree is read-only.
This allows users to bail parsing if an error was *definitely* detected
using the progress callback, as all possible stack versions have a
non-zero error cost.

Introduces a new function that takes in a supertype symbol and returns
all associated subtypes. Can be used by query.c to give better errors
for invalid subtypes, as well as downstream applications like the query
LSP to give better diagnostics.
