Summary: SetScrollInfo incorrectly raises exception

Initial Comment:
I'm using win32all build 163 on Windows XP.  I just got 
an api exception with 0 error code when using 
win32gui.SetScrollInfo.  It looks like the reason for this 
is that PySetScrollInfo treats the result of the 
SetScrollInfo api call as a BOOL, with a false result 
indicating error.  My copy of the win32 api 
documentation states that SetScrollInfo returns the 
current position of the scroll box.  This position 
happened to be 0 in my case, so PySetScrollInfo raised 
an exception.

Also, I just discovered that win32gui.GetScrollInfo also 
generates an api error with a 0 error code.  Looking at 
the source, I note that PyGetScrollInfo does not fill in 
the fMask field before calling GetScrollInfo.  My 
documentation indicates the mask must be initialized to 
specify which members to retrieve.

I'm attaching a diff file to indicate the changes I think are 
needed.  I used the web CVS browser to get the win32gui.i 
file, so the date of the original is wrong, but it is revision 
1.31.  The changes included address both this report and 
report 838065.

Also concerning win32gui.GetScrollInfo, if it creates an 
exception because ok is false, it fails to return NULL.
