8b4f5f039d Alternative strategy to avoid calling stat() 
This is an optimization as it avoids an extra syscall, but it's also a
workaround for fstat being not available on Windows.

0f248e0988 std: Make file copy ops use zero-copy mechanisms 
Use copy_file_range on Linux (if available), fcopyfile on Darwin,
sendfile on *BSDs (and on Linux kernels without copy_file_range).

fbde15fdf4 Fix compile error in os.renameatW 
Introduced in 5e3fa0e94f947c632aa584b9e13bfa2fe241fae1

5e3fa0e94f Add rename to std.fs API 
- 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

5e50d145d9 std: Limit the read/write size on Darwin 
It turns out that the kernel won't read or write more than 0x7fffffff
bytes in a single call, failing with EINVAL when trying to do so.

Adjust the limit and curse whoever is responsible for this.

Closes #6332

3e2e6baee5 Add std.os.getFdPath and std.fs.Dir.realpath 
`std.os.getFdPath` is very platform-specific and can be used to query
the OS for a canonical path to a file handle. Currently supported hosts
are Linux, macOS and Windows.

`std.fs.Dir.realpath` (and null-terminated, plus WTF16 versions) are
similar to `std.os.realpath`, however, they resolve a path wrt to this
`Dir` instance.

If the input pathname argument turns out to be an absolute path, this
function reverts to calling `realpath` on that pathname completely
ignoring this `Dir`.

bdda8fa7a8 Redo GetFinalPathNameByHandle using DeviceIoControl 
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.

747d46f22c Initial draft of GetFinalPathNameByHandle 
This commit proposes an initial draft of `GetPathNameByHandle` function
which wraps NT syscalls and strives to emulate (currently only
partially) the `kernel32.GetFinalPathNameByHandleW` function.
