        * glib/giochannel.c: API changes, fixes to
        error handling, some internal restructuring
        * glib/giochannel.h: API changes, documentation for
        elements in GIOChannel structure
        * glib/giounix.c: Matched API changes, implemented
        backend to set is_readable, is_writeable, is_seekable
        flags, added a test to catch large values of count
        for which the behavior of write() is undefined
        * glib/giowin32.c: Changed to match new prototypes for
        io_close() and io_seek(), removed references to
        G_IO_STATUS_INTR, set is_seekable flag in channel
        creation functions
        * glib.def: Renamed g_channel_error_quark() and
        g_channel_error_from_errno() to g_io_channel_error_quark() and
        g_io_channel_error_from_errno(); added new functions
        g_io_channel_get_buffered() and g_io_channel_set_buffered()
        * docs/reference/glib/glib-sections.txt: Modified iochannel
        section to reflect new functions and API changes
        * tests/iochannel-test.c: Fixed to work with API changes
        * tests/iochannel-test-infile: New file; input file
