A lot of the default.c module code was refactored. The patch is needed
for the IM.


include/my_sys.h:
  Definitions added.
mysys/default.c:
  Added new api call: process_default_option_files. Also some coments
  changed to reflect current state of the code. It takes Basename for
  config file and the function to process options. The function is called
  everytime when we find an option. This way it is possible to get and
  process options from several groups in one file traversal.
BitKeeper/etc/logging_ok:
  Logging to logging@openlogging.org accepted

Putting initialization into .cc will reduce compiler's abilities
to optimize this constant away.
Defines are not OK as they bloat global namespace.
Looking for a way to declare an efficient named constant in reduced
namespace (i. e. in  a class).
Let's try enums: normally they should be implicitly casted to int.
Let's see if we really have a compiler which won't do that.




libmysqld/lib_sql.cc:
  Added explicit cast to int for Protocol::{SEND_DEFAULTS,SEND_NUM_ROWS,
  SEND_EOF}
  flags argument of send_fields() is now int.
sql/protocol.cc:
  flags argument of send_fields is now int.
sql/protocol.h:
  Catch22: Microsoft VC++ won't compile 
  class C { static const int I=1; }.

  Setting dependency on outer tables was added for the above cases.
