[PATCH v7] win32: prefer beginthreadex over CreateThread

["Rose via GitGitGadget" <gitgitgadget@gmail.com>]

From: Seija Kijin <doremylover123@gmail.com>

Use _beginthreadex instead of CreateThread
since we use the Windows CRT,
as Microsoft recommends _beginthreadex
over CreateThread for these situations.

Finally, check for NULL handles, not "INVALID_HANDLE,"
as _beginthreadex guarantees a valid handle in most cases

    win32: prefer beginthreadex over CreateThread
    
    Use pthread_exit instead of async_exit.
    
    This means we do not have to deal with Windows's implementation
    requiring an unsigned exit coded despite the POSIX exit code requiring a
    signed exit code.
