ChangeLog, Makefile.in, initialize.c, .del-io.h~72680822, openfs.c:
Makefile.in (ELF_SO_VERSION): Bump version to be 2.4 since we've added
a new field to the io_channel (app_data).
io.h: Add a new element to the io_channel structure, app_data.
initialize.c, openfs.c: Set io->app_data to point at the filesystem handle.
