This will enables features like expo to maintain separate text-entry state without interfering with each other. The approach is to create a new struct vidconsole_ctx that holds per-client state, initially embedded in vidconsole_priv for the default context. Helper functions vidconsole_ctx() and vidconsole_ctx_from_priv() provide access to the context. Fields moved into vidconsole_ctx: - rows, cols, x_charsize, y_charsize (display metrics) - xcur_frac, ycur (cursor position) - last_ch (for kerning) - cli_index, xmark_frac, ymark (CLI entry state) - ansi, utf8_buf (parsing state) The series also adds ctx_new() and ctx_dispose() operations for drivers to allocate and free per-client context, with implementations for both the normal and truetype console drivers.
