* Rename corpus test functions to allow easy filtering by language
* Use usize for seed argument
* Avoid retaining useless stack versions when reductions merge
We found this problem when debugging an infinite loop that happened
during error recovery when using the Zig grammar. The large number of
unnecessary paused stack versions were preventing the correct recovery
strategy from being tried.
* Fix leaked lookahead token when reduction results in a merged stack
* Enable running PHP tests in CI
* Fix possible infinite loop during error recovery at EOF
* Account for external scanner state changes when detecting changed ranges in subtrees

Instead of having users declare the extern function themselves, they can
pass in the language to `Language.create` in the zig bindings. If they
really want, they can always opt into the `extern fn tree_sitter_LANG()
*const ts.Language` approach.
**Problem:** When resetting the parser during subtree balancing, an
error is thrown:
```
parser.c:2198: ts_parser_parse: Assertion `self->finished_tree.ptr' failed.
```
**Solution:** Reset `canceled_balancing` to false in
`ts_parser_reset()`.
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.

This patch allows users to include the parser by the same path from
local build as well as installed location. Previously it was not
possible to include the header prior to installing the built parser.
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.
