additional limits

[Ulrich Drepper]

Recent Linux kernels have resource limits which are currently not
covered by the ulimit builtin.  The attached patch is a proposal for
adding support.  Beside the question whether the support should be added
in the first place I think the only remaining issue is the character
used to denote the limit on the command line.  I tried to be as
reasonable as possible.

Please let me know whether you agree and if yes, what you intend to add
to your sources?  Thanks,
