Fix problem with strange printout of line numbers, detected on aix52, but...

Fix problem with strange printout of line numbers, detected on aix52, but existing on all platforms, just being masked by init of vars to zero.


client/mysqltest.c:
  Remove lineno_stack, instead use the already existing file_stack and add a new variable lineno to keep track of what line in the file we are at.
mysql-test/r/mysqltest.result:
  Correct test result, "At line 1" should be printed
