/**
* NOTES:
* Fileystem APIs are required for WASI libc support. If you don't need to
* support WASI libc, there is no need to implement these APIs. With a
* few exceptions, each filesystem function has been named after the equivalent
* POSIX filesystem function with an os_ prefix.
*
* Filesystem types
*
* os_raw_file_handle: the underlying OS file handle type e.g. int on POSIX
* systems and HANDLE on Windows. This type exists to allow embedders to provide
* custom file handles for stdout/stdin/stderr.
*
* os_file_handle: the file handle type used in the WASI libc fd
* table. Filesystem implementations can use it as a means to store any
* necessary platform-specific information which may not be directly available
* through the raw OS file handle. Similiar to POSIX file descriptors, file
* handles may also refer to sockets, directories, symbolic links or character
* devices and any of the filesystem operations which make sense for these
* resource types should be supported as far as possible.
*
* os_dir_stream: a directory stream type in which fileystem implementations
* can store any necessary state to iterate over the entries in a directory.
