[svn-r13028] Description:

    Add first pass of "dense" attribute storage to objects.  Lots of parts of
this are stubbed out, but all the tests are passing and I'll work on the corner
cases soon.

    Eliminated several unused parameters from object header message callback
routines.

    Other, miscellaneous code cleanups, etc. (and probably some things I've
forgotten about... :-)

Tested on:
    FreeBSD/32 4.11 (sleipnir)
    Linux/32 2.4 (heping)
    AIX/32 5.? (copper)
