569f7ce49e Merge branch 'improve-windows-networking' 
of https://github.com/BarabasGitHub/zig into
BarabasGitHub-improve-windows-networking

Conflicts:
 lib/std/os.zig

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.

0c355bef9e std: Slim down the error code path in initStaticTLS 
Calling @panic made the executable ~30x times bigger, use a simple
`abort()` and let the user figure out what went wrong.

Supporting ARMv6 (and earlier?) platforms is not a priority.

Closes #6676

96fe971051 std: Minor changes to startup code 
* Smaller startup sequence for ppc64
* Terminate the frame-pointer chain when executing _start
* Make the stack traces work on ppc64
* Make the stack traces coloured on ppc64, some ioctls numbers are
  different and the whole set of constants should be audited.

d87bd3d8af fixups regarding windows wide strings 
* remove GetModuleHandleA from kernel32.zig. use of A functions
   considered harmful.
 * make it a compile error to expose WinMain instead of wWinMain. same
   thing.
 * start code declares wWinMainCRTStartup instead of WinMainCRTStartup
   when it has the choice.

9be2941091 Split openat/close test into two separate tests 
If an older kernel fails the `openat` test because of `AT_FDCWD`
then we don't want to skip the `close` test.

69a55fc560 Allow for advanced non-sequential SQE allocation schemes 
Decouples SQE queueing and SQE prepping methods to allow for non-sequential
SQE allocation schemes as suggested by @daurnimator.

Adds essential SQE prepping methods from liburing to reduce boilerplate.

Removes non-essential .link_with_next_sqe() and .use_registered_fd().

a9b107045f Use load acquire semantics when reading the SQPOLL wakeup flag 
Ensures that the wakeup flag is read after the tail pointer has been
written. It's important to use memory load acquire semantics for the
flags read, otherwise the application and the kernel might not agree on
the consistency of the wakeup flag, leading to I/O starvation.
