This commit recognizes an existing pattern: many operations need some combination of a set of variables, a way to detect cancellation, and sometimes a parser. For example, tab completion needs a parser to execute custom completions, the variable set, should cancel on SIGINT. Background autosuggestions don't need a parser, but they do need the variables and should cancel if the user types something new. Etc. This introduces a new triple operation_context_t that wraps these concepts up. This simplifies many method signatures and argument passing.
