... and mem.copy operations. Requires slightly larger input buffers than result length. Add helper functions std.mem.alignInBytes and std.mem.alignInSlice.
The NtQueryInformationFile with .FileNormalizedNameInformation is only available in Windows 10 1803 (rs4) and later, however there is probably still another route we can go via ntdll.
Make it behave like the read() wrapper for unix systems.
Reading the whole buffer breaks some use-cases like buffered readers
over sockets.

This commit resolves conflicts with the changes to std.os which removed
the EAGAIN error handling interactions with the event loop. The solution
to the conflict was to apply EAGAIN => return error.WouldBlock into the
improved windows networking branch.
This was causing the Dir.readLink test to fail for me locally with error.Unexpected NTSTATUS=0xc0000022. Not sure if PRIVILEGE_NOT_HELD is actually possible or not.
- Moves fs.rename functions to fs.renameAbsolute to match other functions outside of fs.Dir
- Adds fs.Dir.rename that takes two paths relative to the given Dir
- Adds fs.rename that takes two separate Dir's that the given paths are relative to (for renaming across directories without having to make the second path relative to a single directory)
- Fixes FileNotFound error return in std.os.windows.MoveFileExW
- Returns error.RenameAcrossMountPoints from renameatW
+ Matches the RenameAcrossMountPoints error return in renameatWasi/renameatZ
This commit reimagines `std.os.windows.GetFinalPathNameByHandle`
using `DeviceIoControl` to query the OS mount manager for the DOS
(symlink) paths for the given NT volume name. In particular,
it uses `IOCTL_MOUNTMGR_QUERY_POINTS` ioctl opcode to query the
manager for the available moount points.
Favour newer API which uses `NtQueryInformationFile` with class flags
`FileNormalizedNameInformation` and `FileVolumeNameInformation`
instead of lower-level `NtQueryObject`. `NtQueryObject` is still
used as a fallback in case the former are unavailable.
This commit proposes an initial draft of `GetPathNameByHandle` function
which wraps NT syscalls and strives to emulate (currently only
partially) the `kernel32.GetFinalPathNameByHandleW` function.
