LemonBoy 58ee5f4e61 std: Fix metadata corruption in HeapAllocator 
HeapAllocator stores the pointer returned by HeapAlloc right after the
data block and, after the recent allocator refactoring, the space for
this pointer was not taken into account in the calculation of the final
block size.

Fixes #5830

Joran Dirk Greef 4bc1b7a7ac Fix io_uring_sqe to use the names of the first member of each union 
Now we're really future-proof... no more `opflags` creeping in.

When anonymous unions land, we can start using `accept_flags` etc.

Until then, code using this struct won't break when the kernel adds features.

Ryan Liptak 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

LemonBoy 27adb82fda std: Respect user-specified alignment when formatting ints 
This implementation tries to do the right thing (TM) by treating the
sign as part of the number itself, therefore the alignment parameter
applies to both the sign and the digits.

In other words the format string `{:>4}` with -1 as input will not
output `-  1` but `  -1`.

And let's default to right alignment for everything as that's what users
want, especially when printing numbers. Many implementations use
different defaults for numeric vs non-numeric types, let's strive for a
consistent behaviour here.

Joran Dirk Greef b340bbfc1d std: add io_uring library 
This brings io_uring helper methods to Zig for kernels >= 5.4.

We follow liburing's design decisions so that anyone who is comfortable with
liburing (https://unixism.net/loti/ref-liburing/index.html) will feel at home.

Thanks to @daurnimator for the first draft.
