Resolves: bug 471068

Bug Description: winsync doesn't recognize some changes
Reviewed by: nkinder (Thanks!)
Fix Description: Before sending updates to AD, first check to see if the updates still apply.  For modify/add operations, check to make sure the value to add doesn't exist.  If it does, remove it from the list of values in the mod.  If all values are removed, then just skip the modify/add op altogether.  For modify/del ops, check to see if the attribute exists.  If not, just skip the op.  If it does exist, check to see if the values exist, and remove the values from the mod/del op that do not exist anymore.  If all values have been removed, just skip the mod/del op.
I added a new slapi function - slapi_mod_init_valueset_byval - which will init a Slapi_Mod and init the list of values using a valueset.  Fortunately there was already a function for converting a Slapi_Value** to a berval**.
I also fixed a few compiler warnings.
Platforms tested: RHEL5
Flag Day: no
Doc impact: yes - add new function to slapi docs
