oleaut32: MSFT_DoFuncs: "reclength" of the function information record is stored

in a 16 bit int and not in a 8 bit int as previously supposed, using a 0x1ff
mask. Upper 16 bits contains the ordinal number of the function. 
Allocation of the "recbuf" must be modified, to support larger data
(based on a patch by White Snake <whitesnake78(a)mail.com>).
