Solution for wrong behaviour of RegGetValue

While configuration "The Bat!" for Wine I found out a problem with
"RegGetValueA" and "RegGetValueA".
In case dwFlags contains the Bits (RRF_RT_REG_EXPAND_SZ | RRF_RT_REG_SZ) and
not the bit RRF_NOEXPAND the function will return ERROR_INVALID_PARAMETER. This
is wrong behaviour, because expansion will transform a result of type
RRF_RT_REG_EXPAND_SZ into RRF_RT_REG_SZ which satisfies the request.

This behaviour causes "The Bat!" to be unable to access some of its registry
settings, including the registration code. So it refuses to work after the
trial period expired and the code need to be entered manually every time the
program starts up.
Other programs may be affected ass well, especially because the flag RRF_RT_ANY
won't work.

I built a patch for wine 1.1.1 wich solves this issue. This patch applies to
advapi32.
