This is a series of 11 patches, centralizing Mutt screen drawing inside windows (mutt_window_t structures). Currently, the screen drawing and cursor positioning logic is distributed all over the code, resulting in many files having the same logic of where the help, status, message windows are. Additionally, the code directly uses move and mvadd*/mvprint* functions, which means if the layouts are changed, the row/column computation logic needs to be changed all over the place. The patch creates a (very simple) mutt_window_t structure and functions for moving, addch/str/printw, along with clearing the line. The windows keep track of where they are on the screen, allowing the Mutt code to simply position elements relative to the window. During curses initalization, and when the window is resized, the window sizes and positions and recomputed. Also, a new option flags, R_REFLOW is added for options that need to force a reflow when they are changed. Thanks to Richard Russon for pointing out the slang compilation issue.
