Ticket History #3940: Disable MSLSA: ccache in WOW64 on pre-Vista Beta 2 systems

Microsoft did not finish implementing the WOW64 Lsa functions required
for use by the MSLSA: krb5_ccache. When the Lsa functions are called,
they return success but do not return valid data structures. As a
result the calling application crashes.

When building 32-bit versions of the krb5 library we must add a version
check to the MSLSA resolve function that prevents the ccache from being
accessed when the operating system is 64-bit Windows and the version
number is less than Vista/LH Beta 2.

cc_mslsa.c: The WOW64 environment on 64-bit versions of
Windows prior to Vista Beta 2 did not implement the Lsa
functions used by the MSLSA: ccache. This patch disables
the MSLSA: ccache in broken WOW64 environments by checking
the Windows version and the existence and response of the
IsWow64Process API.
