Fixes BUG#60976 "Crash, valgrind warning and memory leak with partitioned archive tables"

Browse Source 
Noted that there was no memory leak, just a lot of used partitioned tables.
Fixed old bug: 'show status' now shows memory usage when compiled with safemalloc.
Added option --flush to mysqlcheck.c to run a 'flush tables' between each check to keep down memory usage.
Changed '--safemalloc' options to mysqld so that one can use --safemalloc and --skip-safemalloc.
Now skip-safemalloc is default (ie, we only do checking of memory overrun during free()) to speed up tests.


client/client_priv.h:
  Added OPT_FLUSH_TABLES
client/mysqlcheck.c:
  Added option --flush to mysqlcheck.c to run a 'flush tables' between each check to keep down memory usage.
mysql-test/mysql-test-run.pl:
  Always run tests with --loose-skip-safemysqld for higher speed
sql/mysqld.cc:
  Changed '--safemalloc' options so that one can use --safemalloc and --skip-safemalloc.
  Now skip-safemalloc is default (ie, we only do checking of memory overrun during free()) to speed up tests
sql/sql_parse.cc:
  Fixed old bug: 'show status' now shows memory usage when compiled with safemalloc.
storage/archive/archive_reader.c:
  Changed all malloc() calls to use my_malloc()/my_free()
  Added checks of malloc() calls.
storage/archive/ha_archive.cc:
  Detect failure if init_archive_reader() and return errno. This fixed assert crash in my_seek().
  Changed all malloc() calls to use my_malloc()/my_free()
