Added Files:
glib/tests/iochannel-test-infile
* 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
for iochannel-test
* tests/unicode-collate.c tests/unicode-normalize.c:
Changed G_IO_FILE_MODE_READ to "r" to match API change
