Hack! Compile fix to provide a "typedef" for "u_int32_t" where it is missing.

Should be replaced by a cleaner solution.


sql/mysqld.cc:
  Hack!  "u_int32_t" is typically defined by system include files, but not everywhere.
  Replacement declaration taken from "libedit/sys.h".
  It might be better to include the BDB header file where this is done more elaborate,
  but I would rather not do this larger change.
