Subject: [PATCH] win/tty: don't touch insert mode or quick edit mode

This is a back-port of 4abad23, whichi is supposed to fix
joyent/node#4809.

The private `original_console_mode` field in the uv_tty_t struct has
been renamed, but couldn't be removed because changing the ABI isn't
allowed on stable branches.
