Cygwin: wincap: add wincap_10_1709, add has_posix_file_info item Various new file info class members adding important POSIX semantics have been added with W10 1709. We may want to utilize them, so add a matching wincaps. Rearrange checking the W10 build number to prefer the latest builds over the older builds. Rename wincap_10 to wincap_10_1507 for enhanced clarity. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

Cygwin: Allow accessing 48 bit address space in Windows 8.1 or later 64 bit Windows started out with a 44 bit address space due to a restriction of the AMD64 CPUs at the time. Starting with Windows 8.1, these CPUs are not supported anymore and Windows switched to the full 48 bit address space supported by AMD64. Cygwin didn't follow suit yet so mmaps are still restricted to the lower 44 bit address space. Fix that by using a system-specific upper address for mmap allocations, 44 bit up to Windows 8, 48 bit starting with Windows 8.1. While at it, move the heap by another 8 Gigs to leave some space for a potential extension of DLL address space, and restrict the mmap lower address so the heap can grow to 32 Gigs before colliding with mmaps.

The assumption that Windows 8 is the same as Windows 8 was not correct, it requires PROCESS_QUERY_INFORMATION as well. Fix that by splitting the Windows 8 wincaps into one for Windows 8 and one for Windows 8.1. Set needs_query_information for Windows 8. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

Cygwin: Allow accessing 48 bit address space in Windows 8.1 or later 64 bit Windows started out with a 44 bit address space due to a restriction of the AMD64 CPUs at the time. Starting with Windows 8.1, these CPUs are not supported anymore and Windows switched to the full 48 bit address space supported by AMD64. Cygwin didn't follow suit yet so mmaps are still restricted to the lower 44 bit address space. Fix that by using a system-specific upper address for mmap allocations, 44 bit up to Windows 8, 48 bit starting with Windows 8.1. While at it, move the heap by another 8 Gigs to leave some space for a potential extension of DLL address space, and restrict the mmap lower address so the heap can grow to 32 Gigs before colliding with mmaps.

Cygwin: Allow accessing 48 bit address space in Windows 8.1 or later 64 bit Windows started out with a 44 bit address space due to a restriction of the AMD64 CPUs at the time. Starting with Windows 8.1, these CPUs are not supported anymore and Windows switched to the full 48 bit address space supported by AMD64. Cygwin didn't follow suit yet so mmaps are still restricted to the lower 44 bit address space. Fix that by using a system-specific upper address for mmap allocations, 44 bit up to Windows 8, 48 bit starting with Windows 8.1. While at it, move the heap by another 8 Gigs to leave some space for a potential extension of DLL address space, and restrict the mmap lower address so the heap can grow to 32 Gigs before colliding with mmaps.

Add comment. Originally, using RtlGetVersion instead of GetVersionEx was supposed to fix the fact that GetVersionInfo returns the wrong kernel version if the executable has been built with an old manifest (or none at all), starting with Windows 8.1. Either this never really worked as desired and our testing was flawed, or this has been changed again with Windows 10, so that RtlGetVersion does the kernel faking twist as well. Since we're only reading the value in the first process in a process tree. the entire process tree is running with a wrong OS version information in that case. Fortunately, the (undocumented) RtlGetNtVersionNumbers function is not affected by this nonsense, so we simply override the OS version info fields with the correct values now.

Cygwin: fork: fix child process permissions, take 3 Per MSDN VirtualQueryEx requires PROCESS_QUERY_INFORMATION. Testing showed that PROCESS_QUERY_LIMITED_INFORMATION is sufficient since Windows 8.1. The assumption that Windows 8 is the same as Windows 8 was not correct, it requires PROCESS_QUERY_INFORMATION as well. Fix that by splitting the Windows 8 wincaps into one for Windows 8 and one for Windows 8.1. Set needs_query_information for Windows 8. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
