It was computing the number of submenus in the branch, rather then the
maximum depth.

C++ doesn't like: GUID GUID; which is valid in C, so replace with
struct _GUID GUID;

secur32: Revert "secur32: Work around ntlm_auth in Samba 3.0.28a being broken for cached credentials".

This reverts commit 7788c8ed, as well
as commit ec443be7. Due to erroneous
user input, these commits actually broke more than they fixed.

This fixes a regression introduced by fb77678e.

Since the table row start is inserted after the rest of the table is
inserted, the cursor is saved, and temporarily moved to the start of the
row to insert the table row start paragraph.  Unfortunately the
paragraph in saved cursor becomes invalid during this insertion and
needs to be updated, so this code introduced a regression once
paragraphs started to be stored in cursors.
