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.

- Revert the following patch from 2.2.0:
When started from a non-Cygwin process, check if $HOME starts with a
slash (absolute POSIX path). Otherwise ignore it.
- Fix output of /proc/cpuinfo in terms of cpu topology and cache size for
modern CPUs and modern Windows OSes supporting more than 64 logical CPUs.
Don't perform RFC2307 account mapping without account DB * fhandler_disk_file.cc (fhandler_base::fstat_by_nfs_ea): Only try to map user and group info per RFC2307 if account info is fetched from Windows account DB. (convert_samba_sd): Ditto. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

Cygwin: Try to fix potential data corruption in pipe write * fhandler.cc (fhandler_base_overlapped::raw_write): When performing nonblocking I/O, copy user space data into own buffer. 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.
