Lazily allocate 'struct regsets_info'::disabled_regsets.
There's no need for every arch to pre-allocate disabled_regsets.
Chances are the array won't be used.
(I have a hunch that with some more work we could dispense with
initialize_regsets_info.)
Tested on x86_64 Fedora 17 w/ -lmcheck.

* linux-low.c (regset_disabled, disable_regset): New functions.
(regsets_fetch_inferior_registers)
(regsets_store_inferior_registers): Use them.
(initialize_regsets_info); Don't allocate the disabled_regsets
array here.
* linux-low.h (struct regsets_info) <disabled_regsets>: Extend
comment.
