libc was added as a dependency to vnet for error mapping.
This breaks JS targets.
Removed the dependency, and removed the mapping functions.
Will be added again in the wasi crate.
- Removed generation_arena which was causing some serious leakages of files and sockets
- Added OsError for NetworkErrors so that "Too Many Open Files" is properly passed
- Local networking will now cap at 10 sockets in the backlog
- Added the missing shutdown error code
- Removed the inodes lock around most of the WASI syscalls
- Fixed some race conditions in the event notifications for WASI
- The polling loop will now only notify a closed socket once
- Event notifications now uses Wakers rather than MPSC
- Some socket errors now return the right codes which prevents panics in WASM
- Fixed a bug where the file read and write guards might release the file before the lock
- The inode seed is now much safer preventing overlaps
- The fd seed is now much safer preventing overlaps
- Closing files is now implicit rather than explicit reducing possibliities for error
- Forking of file descriptors is now much simplier
- Polling events will now be returned in random order to prevent some race conditions
- Removed a number of memory allocations which were wasting memory and performance
- Sockets now only copy the send and recv data once rather than multiple times
- Avoiding a memory copy on all socket reads and writes using a new `copy_from_slice` instead
- File openers no longer box the implementation avoiding a memory allocation on all file access
- Polling sockets rather than using an async function which significantly reduces locking contention and removes an box operation
- Futex now uses wakers rather than broadcasts which makes them more efficient and durable
- Converted many async functions into sync functions in vnet
- Sleeping no longer allocates memory
- Avoiding a number of WasiEnv clones which was impacting performance and memory efficiency

Removes the websocket support from wasix.
Websockets are a high level concept.
They should not be integrated so deeply into the core of wasix.
For client connections, we will want to add support for websocket
clients into the custom wasix_http_client bindings.
For servers, the support should go into the custom wcgi server bindings.
Removes the old wasix http request support from the vnet and wasi crates.
This was replaced by the recently introduces wasix_http_client_v1 bindings.
Motivation: http requests are a high level functionality, not a fundamental
networking concept.
They shouldn't be integrated this deeply into the networking stack.
Wasix modules can either bring their own http client that uses regular
sockets, or use the wasix http client bindings.
Additional upside is removal of quite a bit of http related code in the
networking stack.
Note: the same should probably be done for the WebSocket support in vnet.
- Implemented multi-threading for both JS and SYS, plus other WASIX implementations
- Added a longjmp capability required for bash and other WASIX implementations
- Added real signals to WASIX
- Added a stack unwinding and winding functionality
- Implemented memory forking which will be used for process forking
- Added the ability to fork the current process
- Added the vfork functionality
- Moved over to the WasiPipe implementation
- Added more syscalls needed for bash on WASIX
- Ported wasmer-os into wasmer
- Added a union file system and the character devices
- Moved the cursors to the file handles rather than the file so that they are multithread safe and can handle concurrent IO
- Reimplemented the poll_oneoff functionality to support full ASYNC
- Added support for mapping directories in the host file system into WASIX sandbox file systems
- Implemented fully ASYNC sockets and emulated ASYNC files
- Made the file locks more granular to allow for concurrent poll and accept operations
