    Support handing off socket write permission to external code.
    
    Libraries like Xlib, some XCB language bindings, and potentially others
    have a common problem: they want to share the X connection with XCB. This
    requires coordination of request sequence numbers.  Previously, XCB had an
    Xlib-specific lock, and allowed Xlib to block XCB from making requests.
    Now we've replaced that lock with a handoff mechanism, xcb_take_socket,
    allowing external code to ask XCB for permission to take over the write
    side of the socket and send raw data with xcb_writev.  The caller of
    xcb_take_socket must supply a callback which XCB can call when it wants
    the write side of the socket back to make a request.  This callback
    synchronizes with the external socket owner, flushes any output queues if
    appropriate, and then returns the sequence number of the last request sent
    over the socket.

    Track 64-bit sequence numbers internally.
    
    External APIs that used 32-bit sequence numbers continue to do so.

    Use sequence number ranges in pending replies
    
    This allows optimizing adjacent pending replies with the same flags, and
    will help support default flags for a range of future requests.

    Inline _xcb_lock_io, _xcb_unlock_io, and _xcb_wait_io.
    
    These functions are once again a single pthread call, so just make that
    call directly.
