The following helper functions have been added to aid with parsing mouse buttons from a string: 1. `get_mouse_bindsym`: attempts to parse the string as an x11 button (button[1-9]) or as an event name (ex BTN_LEFT or BTN_SIDE) 2. `get_mouse_bindcode`: attempts to parse the string as an event code and validates that the event code is a button (starts with `BTN_`). 3. `get_mouse_button`: this is a conveniency function for callers that do not care whether a bindsym or bindcode are used and attempts to parse the string as a bindsym and then bindcode. None of these functions are used in this commit. The sole purpose of this commit is to make the larger set more granular and easier to review/manipulate. There will be a series of commits following this one that will modify any command which uses a mouse button to use these helpers.
