The `rbuffer_consumed` was being passed a consumed count from another buffer, causing integer overflow in `rbuffer_relocate`. Fixes neovim#1343

changed the title
- Extract `process_interrupts` out of `convert_input` - Instead of waiting for os_breakcheck/os_inchar calls, call `convert_input` and `process_interrupts` directly from the read callback in input.c. - Remove the `settmode` calls from `job_wait`. Now that interrupts are processed in the event loop, there's no need to set the terminal to cooked which introduces other problems(ref 7.4.427)

Input buffer must be bigger than read buffer to ensure it always has space for converted data.
The `vim_feedkeys` must be deferred because it can potentially free the buffer passed to `os_inchar`(which in turns calls `vim_feedkeys` indirectly). The new `vim_input` function can be used to emulate user input(Since it does not mess with the typeahead, it is safe to execute without deferring).

This is also good because it will simplify handling ctrl+c in the middle of server->client msgpack-rpc calls
