Bug Fixes
---------
Fix /proc/cpuinfo topology and cache size info * autoload.cc (GetLogicalProcessorInformationEx): Import. (SetThreadGroupAffinity): Import. * fhandler_proc.cc (add_size): New macro. (get_msb): New inline function. (mask_bits): Ditto. (format_proc_cpuinfo): Drop handling of old CPUs. Check if we're running on a OS version supporting porcessor groups. If so, use SetThreadGroupAffinity to set thread affinity. Improve cache info to include 3rd level cache on Intel CPUs. Improve multi core info. * wincap.h (wincaps::has_processor_groups): New element. * wincap.cc: Implement above element throughout. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

Don't call LsaLookupSids if we're not utilizing Windows account DBs * grp.cc (internal_getgrfull): Drop asking caches. Explain why. (internal_getgroups): In case we're not utilizing the Windows account DBs, don't call LsaLookupSids but iterate over the group SIDs in the token and call internal_getgrsid for each of them. Explain why. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

- Don't call LsaLookupSids to fetch group information and don't perform RFC2307

Add longish comment to explain why. * fhandler.h (fhandler_base_overlapped::atomic_write_buf): New member. (fhandler_base_overlapped::fhandler_base_overlapped): Initialize atomic_write_buf. (fhandler_base_overlapped::fhandler_base_overlapped): New destructor, free'ing atomic_write_buf. (fhandler_base_overlapped::copyto): Set atomic_write_buf to NULL in copied fhandler.

- Precautionally fix a potential data corruption problem in pipe I/O, only
actually observered in Wine yet. However, MSDN language indicates this
might be a problem on real Windows as well.
