Fixed compiler warnings and other bugs found by buildbot.

client/mysqltest.cc:
  Free mutex after usage (fixes valgrind warnings in embedded server)
mysql-test/include/gis_keys.inc:
  Fixed failure in innodb.gis_test
mysql-test/r/gis.result:
  Updated result
mysql-test/suite/innodb/r/innodb_gis.result:
  Updated results
mysql-test/suite/innodb/t/innodb_bug38231.test:
  Added handling of timeouts (happend on some servers in buildbot)
mysql-test/suite/innodb_plugin/r/innodb_gis.result:
  Updated results
mysql-test/suite/innodb_plugin/t/innodb.test:
  Use error names instead of numbers
mysql-test/suite/innodb_plugin/t/innodb_misc1.test:
  This test requires utf8
mysql-test/suite/innodb_plugin/t/innodb_mysql.test:
  This test requires Xtradb
sql/sql_base.cc:
  Don't print table names for placeholders.
sql/sql_show.cc:
  Temporary fix:
  Save and restore db and table_name in mysqld_show_create (to get rid of valgrind warning)
  A better solution that needs to be investgated is to not change these fields in mysql_derived_prepare()
sql/sql_view.cc:
  Fixed valgrind warning
storage/xtradb/handler/ha_innodb.cc:
  Don't access THD directly
