Fix broken embedded build (broken by the patch for Bug#12713, first part).

client/mysqltest.c:
  Remove a call to my_message() (server call) in case of a client error.
  It asserts in the embedded build now, since is called after send_ok().
libmysqld/emb_qcache.cc:
  Use net_send_eof (embedded implementation) in embedded query cache/
  send result to client, since send_eof currently does not
  send anything.
libmysqld/emb_qcache.h:
  Declare net_send_eof.
libmysqld/lib_sql.cc:
  Fix the main loop of the embedded server to use the new Diagnostics_area
  API.
sql/log.cc:
  Silence errors of open_performance_schema_table. This function
  is called for general logging, and it happens after the error
  has been sent to the client, and thus triggers an assert.
storage/myisam/ha_myisam.cc:
  Remove an old hack that broke repair.test in embedded build:
  unless we clear an error here, the server attempts to send OK after
  ERROR. This currently asserts.
