Fix bug #7339 - MSDFS is non-functional in 3.5.x
In the refactoring around filename_convert, the split between the functions resolve_dfspath() and resolve_dfspath_wcard() was lost, leaving us only with resolve_dfspath_wcard(). Internally resolve_dfspath_wcard() calls dfs_redirect() only with a "allow_wcards" flag of true, wheras the old resolve_dfspath() would call with a value of false. The loss of this case causes dfs_redirect to always masquerade DFS links as directories, even when they are being queried directly by a trans2 QPATHINFO call. We should only masquerade DFS links as directories when called from a SMBsearch or trans2 findfirst/findnext - which was the intent of the "allow_wcards" flag. This patch adds back an allow_wcards bool parameter to resolve_dfspath_wcard(). This bool is set from the state of the ucf_flags when filename_convert() is called. I will follow this up with a new smbclient-based torture test that will prevent us from ever regressing our DFS support again. Jeremy.
