Subject: char: use a const CharDriver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

No need to allocate & copy fields, let's use static const struct instead.

Add an alias field to the CharDriver structure to cover the cases where
we previously registered a driver twice under two names.
