commit 37daf101007e92038560913b56ac0330fce3d230

    Windows: define AFS_IHANDLE_PIO_ENV for ihandle pio
    
    Support for positional i/o in the ihandle package was added to the
    windows platform in commit 50b6a116a1c412d0e6d7442d13d6e92c9dbb35ee
    using native windows functions.  That commit also defined HAVE_PIO in
    the windows version of the afsconfig.h file. Unfortunately, that
    definition of HAVE_PIO is not limited to the ihandle package.
    
    Remove the project-wide HAVE_PIO definition from the windows afsconfig.h
    file and define the new AFS_IHANDLE_PIO_ENV symbol when position i/o
    support is available in the ihandle package.
    
    Build the fallback ih_pread and ih_pwrite functions (which use lseek)
    only when positional i/o is not available in the ihandle package for the
    current platform.
    
    Use AFS_IHANDLE_PIO_ENV instead of HAVE_PIO in ih_open() to determine
    when it is is safe to share ihandles among threads.
