[PATCH] procfs.c: allocate saved_entryset, saved_exitset

[Kevin Buettner <kevinb at cygnus dot com>]

I've just committed the patch below as an "obvious" fix.

In my 2001-03-26 changes to procfs.c, I turned saved_exitset and
saved_entryset (which are both members of struct procinfo) into
pointers.  I needed to make these members pointers because the
type, sysset_t, does not have a fixed size on AIX 5.  Since it
doesn't have a fixed size, the size needs to to be determined
at runtime and the corresponding structs need to be dynamically
allocated.

Anyway... that's the part I forgot, the allocation and deallocation
of these structs when creating/destroying a struct procinfo.  The
patch below corrects that oversight.

Thanks to Peter Schauer for bringing this problem to my attention.

	* procfs.c (create_procinfo): Allocate space for saved_entryset
	and saved_exitset.
	(destroy_one_procinfo): Free space allocated to saved_entryset
	and saved_exitset.
