Alex Orlenko 121971f54e Add Lua::set_memory_category and Lua::heap_dump functions to profile Luau memory usage.
This functionality uses Luau private api to dump heap mempory in JSON format for inspection.
The new type `HeapDump` represents memory snapshot with some basic API to calculate stats.

Alex Orlenko a2728928cf Temporary disable some send tests on nightly
Aparently there is a regression in the compiler and sync detection does not work correctly

Alex Orlenko 0619f264de Add Lua::traceback function to generate stack traces at different levels
This is similar to `debug.traceback`, through does not require debug module.

Alex Orlenko 1152519074 Add add_method_once and add_async_method_once UserData methods (experimental).

userdata instance during the call.

Alex Crichton 6e353d6c9f Build/test wasm32-wasip2 in CI (#649)
This is a follow-up from mlua-rs/lua-src-rs#13 which verifies/tests that
mlua/lua all work when compiled for a WASI target. While this doesn't
have formal documentation yet it also codifies in CI configuration how
to build for WASI and get tests passing (notably C compiler
configuration and some misc Rust flags).

This moves some `dev-dependencies` that don't compile for
`wasm32-wasip2` to a different section of the manifest. This
additionally annotates panicking tests with `#[cfg(not(panic =
"abort"))]` to skip those tests on WASI.

This does not test either the `send` or `async` feature at this time.
Testing `send` requires threads which WASI does not yet support, and
testing `async` requires more support in Tokio which is not currently
there yet.

Alex Orlenko 09da7a41e5 Add new serde option "detect_mixed_tables"
This option would allow detecting mixed tables (with array-like and map-like entries or several borders)
to encoding them chosing the best method (as a map or as a table).

Alex Orlenko d399559d30 Add Lua::yield_with to allow yielding Rust async functions and exchange values between Lua coroutine and Rust.
This functionality is similar to `coroutine.yield` and `coroutine.resume` without C restrictions.

Alex Orlenko 30735d5ff1 Fix thread recovery when pushing a bad arg
We should not erase thread stack if a bad argument is pushed before resuming the thread.

Alex Orlenko 347856b806 Do not try to yield at non-yielable points in Luau interrupt
In particular we cannot yeild across metamethod/C-call boundaries.
This behaviour matches with Lua 5.3+ yielding from hooks only at safe points.
Closes #632

Alex Orlenko 774a63bece Add Buffer::cursor() method

Alex Orlenko f0806a6d62 Lower fastpath table creation limit to 1 << 26
When Lua is configured without memory restrictions, we use fastpath for table creation (unprotected mode).
In generally it's safe as long as we `abort()` on allocation failure.
However some Lua versions have additional restrictions on table size that we need to adhere in mlua too.
Probably Luau has the lowest limits.
Fixes #627

Alex Orlenko cb153a52b2 Make Luau registered aliases case-insensitive
Executing `require("@my_module")` or `require("@My_Module")` should give the same result and use case-insensitive name.
See #620 for details

Alex Orlenko b1c69d3005 Use to_bits comparison to check if a float value can be represented as an integer losslessly.
This allows to simplify the code while still maintaining "negative zeros" edge case.
Thanks @JasonHise for the suggestion.

Alex Orlenko 815d1bd7c9 Better handling negative zeros to match Lua 5.3+ behavior
In Lua 5.3+ the function `lua_isinteger` returns "false" for -0.0 numbers.
In earlier Lua versions we should follow the same behavior to avoid losing the sign when converting to Integer.

Alex Orlenko b1f73ec29d Update Luau Compiler methods to better control extra options:
- Add `add_mutable_global`
- Add `add_userdata_type`
- Replace `set_library_constants` with `add_library_constant`
- Add `add_disabled_builtin`

Alex Orlenko 25955893e0 (Luau Require) Resolve Lua file path relative to the current directory
and unrelated to Rust source file location.
When a Lua file is required inside a Rust file (in a chunk), we should resolve the Lua file relative to the current directory,
instead of relative to the Rust chunk path.
The Rust file location is an internal information that does not exist when the compiled binary runs.
