The default implementation of write_register keeps DC low for the first
byte only. SH1106 requires DC to be low for all bytes of a multi-byte
command. To deal with this limitation we currently use a separate call
to write_reg for each single command byte what is not really efficient.

Therefore override the default implementation of write_register with an
own one which keeps DC low for all bytes.

code is shared, only the read function has to behave differently in

speakup: convert screen reading to 16bit characters

This adds 16bit character support to most of the screen reading by
extending characters to u16 throughout the code.

Non-latin1 characters are assumed to be alphabetic type for now.

non-latin1 vt_notifier_call-provided characters are not ignored any
more, and the 16bit character returned by get_char is not truncated any
more. For simplicity, speak_char still only supports latin1 characters.
Its direct mode however does support 16bit characters, so in practice
this will not be a limitation, non-latin1 languages will be handled by
the synthesizer. spelling words does not support direct mode yet, for
simplicity for now it will ignore 16bit characters.

For simplicity again, speakup messages are left in latin1 for now.

This extends the synth buffer slots to 16bit, so as to hold 16bit

synth_buffer_getc and synth_buffer_peek now return 16bit characters.
Speech synthesizers which do not support characters beyond latin1 can
use the synth_buffer_skip_nonlatin1() helper to skip the non-latin1
characters before getting or peeking. All synthesizers are made to use
it for now.

This makes synth_buffer_add take a 16bit character. For simplicity for

synth_putwc, synth_putwc_s, synth_putws and synth_putws_s helpers are
