core: optimize the removal of lines in buffers (a lot faster to clear/close buffers with lot of lines)

Browse Source 
The update of variables "buffer_max_length" and "prefix_max_length" in struct
t_gui_lines is now delayed and made during the main refresh (in main loop).

For a buffer with 50K lines, it is up to 3300 times faster to clear/close it.
For a buffer with 4096 lines (default limit), it is up to 120 times faster.
