Some bug fixes and a feature add to mysql-test-run

client/mysql.cc:
  Fixed Bug#981  ".mysql_history is lost if mysql clinent exit when out of space"
client/mysqlbinlog.cc:
  Fix for mysqlbinlog, mysql_close() needs to be called.
libmysql/Makefile.shared:
  Added use of my_rename()
mysql-test/mysql-test-run.sh:
  Added possibility to add file t/testname.disabled. This will disable a
  test with same base name. Additionally, if the .disabled file contains text,
  it will be appended as a comment after the test during run.
