New API: hb_buffer_[sg]et_replacement_codepoint()
With this change, we now by default replace broken UTF-8/16/32 bits
with U+FFFD. This can be changed by calling new API on the buffer.
Previously the replacement value used to be (hb_codepoint_t)-1.
Note that hb_buffer_clear_contents() does NOT reset the replacement
character.
