WL#2930 mysqltest++

 - Updated after valgrinding


client/mysqltest.c:
  Move initialisation of dynamic strings to top of function so that variables are always inited before free
  The workaround for 15518 moved to last in function
  Add check for "--" comments without any comment,. to avoid read of uninit memory
mysql-test/mysql-test-run.sh:
  Add printout of valgrind errors from mysqltest when test with valgrind  has completed
