Prior to this fix, fish was rather inconsistent in when $status gets set in response to an error. For example, a failed expansion like "$foo[" would not modify $status. This makes the following inter-related changes: 1. String expansion now directly returns the value to set for $status on error. The value is always used. 2. parser_t::eval() now directly returns the proc_status_t, which cleans up a lot of call sites. 3. We expose a new function exec_subshell_for_expand() which ignores $status but returns errors specifically related to subshell expansion. 4. We reify the notion of "expansion breaking" errors. These include command-not-found, expand syntax errors, and others. The upshot is we are more consistent about always setting $status on errors.
