commit 77511a82b1efe2ecde013b3f20ff71605aa61971
Author: Alan Coopersmith <alan.coopersmith at oracle.com>
Date:   Sat Nov 19 00:55:38 2011 -0800

    Remove Malloc wrapper and its MallocFailed helper
    
    Only two calls left, one of which was already checking for failure.

commit 3570de4c260cf45d202e3577d13385d722d043d1
Author: Alan Coopersmith <alan.coopersmith at oracle.com>
Date:   Sat Nov 19 00:49:52 2011 -0800

    Replace many malloc(strlen)+strcpy calls with strdup calls
    
    Some used local Malloc wrapper that checked for a NULL return and
    exited, so had to add matching checks for strdup returning NULL.

commit c6b02069954ef83f8766d6a157b0a95939523d32
Author: Alan Coopersmith <alan.coopersmith at oracle.com>
Date:   Sat Nov 19 00:30:44 2011 -0800

    Remove unnecessary Realloc wrapper
    
    The one caller already checks for and handles failure, so having a
    wrapper that just adds another check for allocation failure isn't
    useful.

commit c44cb256ce8660c9d529374b7596531dad1a5376

    Remove a bunch of unnecessary casts with malloc, free & memcpy calls
    
    With modern compilers and headers, they cause more problems than they
    solve and just hide real issues.
