[PATCH] rename ->open and ->close ops in struct_io_manager

[Eric Sandeen <sandeen@redhat.com>]

glibc recently added for -D_FORTIFY_SOURCE=2 error checking
open/open64/openat/openat64 macros that verify proper use, including
checking that a mode is supplied with O_CREAT.

These macros re-#define "open," which does not play nice
when that name is used elsewhere.

Renaming open (and for symmetry, close) in struct_io_manager
seems like one way to go.  On the one hand I hate to have to
change code for this, but on the other hand it may not be worth
fighting.  Any thoughts?

Thanks,
-Eric

----

rename struct_io_manager's ->open and ->close members so that
recent glibc's redefined "open" for -D_FORTIFY_SOURCE=2 does
not clash with it.
