Fixes for BUG#10039 "MEMORY engine is reported as HEAP",

BUG#9738 "SHOW VARIABLES still displays the deprecated 'log_update' in 5.0",
BUG#9542 "MySQL dies with signal 11 when it is using non-existent location of binary logs"



mysql-test/r/create.result:
  MEMORY, not HEAP
mysql-test/r/ps_1general.result:
  order changed in SHOW STORAGE ENGINES
mysql-test/r/variables.result:
  MEMORY, not HEAP
sql/handler.cc:
  the array of storage engine names is searched in index order, so we must put the preferred name
  before the alias so that the preferred name is printed by MySQL instead of the alias.
sql/log.cc:
  TC_LOG::open(): don't try to open if the index (relevant only for binlog TC log)
  could not be opened.
sql/set_var.cc:
  --log-update is deprecated and replaced by --log-bin so don't show log_update in SHOW VARIABLES.
