[PATCH 06/33] tty: vt: use sane types for userspace API

["Jiri Slaby (SUSE)" <jirislaby@kernel.org>]

As discussed earlier (see the Link below), use the preferred ioctl types
in vt.h (__u8, __u16, ...).

These types are already used for the new VT_GETCONSIZECSRPOS.
Therefore, the necessary includes are already present. Since now, the
types are used for every structure defined in the header now.

Note the kernel is built with -funsigned-char, therefore 'char' becomes
'__u8' in here.
