* ace/Signal.i: Changed to use new Object Manager member.

* ace/Object_Manager.cpp: Added a new member to the Object
Manager--default_mask.  This is the default signal mask employed
by ACE_Sig_Set.  Moving the object into the OM saves cycles b/c we
only construct it once and just re-use every time.

* ace/Handle_Set.cpp: Added two new macros--ACE_DIV_BY_WORDSIZE and
ACE_MULT_BY_WORDSIZE--which either divide or multiply the argument
by ACE_Handle_Set::WORDSIZE.  The manner in which this is
accomplished is governed by the #define
ACE_USE_SHIFT_FOR_EFFICIENCY--when defined, ACE tries to use
shifts to implement multiplication and division rather than actual
multiply and divide operations.  Currently this is disabled.
