[PATCH master 38/39] console: introduce helper for printing binary buffers as-is

[Ahmad Fatoum]

Both console_putc(), console_puts() and console->puts always do
LF to CRLF conversion. For cases where this is not desired, code must
manually call console_putc in a loop.

Add a helper to simplify this.
