relrelb e9167cf43c swf: Add minimal offset table enforcement in `DefineFont2/3` 
Previously, the offset table and code table offset were completely
ignored. But as it seems, Flash does look into these offsets in
order to avoid exceedingly reading glyph shapes. For now, avoid
exceedingly reading empty and 1-byte glyph shapes, and add debug
assertions that verify the correctness of the offset table and code
table offset, to help diagnosing related bugs in the future.

Mike Welsh 55da3cd7d0 chore: Add .cargo/config.toml for workspace-level lint config 
Currently it is not directly possible to configure lints for the
entire workspace via TOML, which forced us to repeat `#![allow]`
blocks in each crate.

embark pointed out this workaround to configure lints at the
workspace level via RUSTFLAGS:

https://github.com/EmbarkStudios/rust-ecosystem/issues/22#issuecomment-947011395

Remove the common `#![allow]` blocks and switch to this method for
global lint config.

Temporarily allow `needless_borrow` lint, buggy pending this fix:

Mike Welsh b181debff6 swf: Use bitflags for `avm1::GetUrl2` 2022-01-17 21:35:57 -08:00
Mike Welsh 4c3e14eae5 core: Clean up `DefineFunction` action 
* Have `DefineFunction` and `DefineFunction2` go through the same
   code path by implementing `From<DefineFunction>` for
   `DefineFunction2`.
 * Change `register` to a `Option<NonZeroU8>` for size optimization.
 * Add `function::Param` to store param info instead of a tuple.

Mike Welsh 9141451ca1 swf: Use structs for avm1 `Action` variants 
Use a struct for all variants of `avm1::Action`.
This makes the style more consistent instead of using a mix of
struct and tuple variants, and allows the data to be easily passed
around.

* Use `TryFlags` instead of hard-coded binary literals.
* Rename `try_length`, `catch_length`, `finally_length` to `try_size`,
`catch_size`, `finally_size` to match SWF19 namings.
* Refactor write and fix a few bugs there:
    * The actions length should not include the try, catch, finally
    bodies, only the metadata of `flags`, `try_size`, `catch_size`,
    `finally_size` and catch variable (either as `u8` or `SwfStr`).
    * A placeholder byte should be written in place of the catch variable
    when there is no catch clause.

Also, gracefully handle malformed ClipActions that are only 1 or 0
