Mechanical class renaming:

Protocol_simple->Protocol_text; Protocol_prep->Protocol_binary
and also THD::protocol_simple->THD::protocol_text,
THD::protocol_prep->THD::protocol_binary.
Reason: the binary protocol is not bound to be used only with
prepared statements long term (see WL#3559 "Decouple binary protocol
from prepared statements"). Renaming now is pressing because
the fix for BUG#735 "Prepared Statements: there is
no support for Query Cache" will introduce a new member
in class Query_cache_flags telling about the protocol's nature.
Other reason: "simple" is less accurate than "text".
Future patches for BUG#735 will rely on this cset.
