- e8f1b1a8 'Do not send TextInputEvent for control characters': set
K_ESC, K_BKSP, K_ENTER to '\0' in all keymaps (US, GB, Dvorak, Azerty,
Bepo, IT). Control characters are now produced via fbcond's
scancode handler (0x1C -> \n, 0x0E -> \x7F) instead of via the
character field. This pairs with the fbcond 0x1C Enter fix.
- c3789b4e 'only perform a single write and assert the amount written':
add assertion in write_event that the kernel returned the full
expected byte count. Prevents silent short writes in the input
event path.
