Fixed compiler warnings.

client/mysql_upgrade.c:
  Fixed problem with mysql_upgrade being dependent
  on local my.cnf files and problem with memory not being freed.
client/mysqltest.c:
  Changed type to avoid warning.
cmd-line-utils/readline/xmalloc.c:
  Fix to avoid warning.
include/my_dbug.h:
  To disable parts from code in non-debug more.
sql/field.cc:
  Fixed warning.
sql/ha_archive.cc:
  Fixed warning.
sql/ha_berkeley.cc:
  Added casts to avoid warnings.
sql/ha_ndbcluster.cc:
  Fixed warnings.
sql/log.cc:
  Added casts to avoid warnings.
sql/slave.cc:
  Avoid warning.
sql/sql_repl.cc:
  Avoid warning.
support-files/compiler_warnings.supp:
  Added disabled warnings to compiler_warnings.supp file.
  These are backported mainly from 5.1 suppress file, but there
  are some additional new ones.
