- Move the encoding/decoding from the Filesystem implementation to the
individual handles.
- Move each handle into an core.apis.handles package from the main fs
API.
- Move the HTTP response to inherit from these handles.
- Allow binary handles' read function to accept a number, specifying
how many characters to read - these will be returned as a Lua string.
- Add readAll to binary handles
- Allow binary handles' write function to accept a string which is
decoded into the individual bytes.
- Add "binary" argument to http.request and friends in order to return
a binary handle.
- Ensure file handles are open when reading from/writing to them.
- Return the error message when opening a file fails.
table.unpack will often stop at the first nil value, meaning some event
arguments may be discarded. By storing the number of arguments through
table.pack, and then using that count when unpacking, we can ensure all
values are returned/resumed with.
