Include files are outdated comparing to current 5.5 server or MySQL connector C

I noticed that include/mysqld_error.h didn't contain ER_UNSUPPORTED_PS, and simple diff shows that there is a lot of stuff that is also missing, comparing to one from maria/5.5 or from mysql-connector-c-6.0.2. I don't know whether it only concerns mysqld_error.h or it's a common problem with the include/* files, but in any case it's better to synchronize them with current 5.5 which we are supposed to support.
