The new API now covers the entire character driver protocol, while hiding all the message details. It should therefore be used by all new character drivers. All existing drivers that already made use of libchardriver have been changed to use the new API. As one of the most important API changes, support for scatter and gather transfers has been removed, as several key drivers already did not support this, and it could be supported at the safecopy level instead (for a future readv/writev). Additional changes include: - respond to block device open requests to avoid hanging VFS threads; - add support for sef_cancel. Change-Id: I1bab6c1cb66916c71b87aeb1db54a9bdf171fe6b
