console: add a flag to prepend '\r' in the multi-console framework
Currently, console drivers prepend '\r' to '\n' by themselves. This is
common enough to be supported in the framework.
Add a new flag, CONSOLE_FLAG_TRANSLATE_CRLF. A driver can set this
flag to ask the framework to transform LF into CRLF instead of doing
it by itself.
