Routine Description:

    This function is called as an NTSD extension to format and dump
    an object attributes structure.

Arguments:

    hCurrentProcess - Supplies a handle to the current process (at the
        time the extension was called).

    hCurrentThread - Supplies a handle to the current thread (at the
        time the extension was called).

    CurrentPc - Supplies the current pc at the time the extension is
        called.

    lpExtensionApis - Supplies the address of the functions callable
        by this extension.

    lpArgumentString - Supplies the asciiz string that describes the
        ansi string to be dumped.

Return Value:

    None.

  Description:
    This function takes the WAM_REQUEST object and prints out
    the details for the same in the debugger. The granularity of the
    deatils are controlled by the verbosity flag

  Arguments:
    pwreqOriginal - pointer to the location where the original WAM_REQUEST
                  object is located.
                  Note: pwreqOriginal points to object inside debuggee process
    pwreq         - pointer to the WAM_REQUEST object that is a copy
                  of the contents located at [pwreqOriginal]
                  Note: pwreq points to object inside the debugger process
    Verbostiy   - level of details requested.

  Returns:
