Two more patches

[David Carter]

Both at: http://www-uxsup.csx.cam.ac.uk/~dpc22/cyrus/patches/2.3cvs/

sync_catch_null.patch
=====================

Companion to new reconstruct -u/-U options:

Don't replace messages on the replica if one or both of the UUIDs is NULL.

Also fixes a silly bug in find_reserve_messages(): sync_client will have 
been missing some messages on the server which could be RESERVEd and then 
copied by reference (UPLOAD COPY) rather than value (UPLOAD PARSED).

reconstruct.patch
=================

Trivial fix when reporting errors.
