Noticed that GetLastError() could return 0 (error code for a successful operation) -- probably due to win32 calls performed during logging --> Store the result in a variable before writing log messages, just in case ... Signed-off-by: Jyrki Gadinger <nilsding@nilsding.org>
Also added some extra logging when InitializeAcl fails, and a regression test. Signed-off-by: Jyrki Gadinger <nilsding@nilsding.org>

When changing the ACL to read-write, the size of the ACL struct does not increase as all previously defined (and -- due to a bug in < 4.0.2 -- wrongfully duplicated)
ACCESS_DENIED_ACEs are dropped.In case the current ACL size is already too big to fit a new
ACCESS_DENIED_ACE(e.g. when trying to make a folder read-only again), assume the ACL is full of duplicate entries and just™ reuse the same ACL size...Also added a test to verify that the client no longer fails modifying ACLs with too many of these access denied ACE entries. And logs printing
WindowsErrors are fixed once again -- seems like using it directly from withinqDebugwill end up changing the value returned by theGetLastError()function...Related previous PRs: #9109, #9157; may resolve #8860
