[Scudo] Delete unused flag 'rss_limit_mb'.

[hctim]

Summary

EOM.

[cryptoad]

I should implement that someday, but nobody seems to have a need for it.

SCUDO_FLAG(bool, delete_size_mismatch, true,
            "Terminate on a size mismatch between a sized-delete and the actual "
            "size of a chunk (as provided to new/new[]).")
 
 SCUDO_FLAG(bool, zero_contents, false, "Zero chunk contents on allocation.")

            "Pattern fill chunk contents on allocation.")

-           "values disable the feature.")

 SCUDO_FLAG(bool, may_return_null, true,
            "Indicate whether the allocator should terminate instead of "
            "returning NULL in otherwise non-fatal error scenarios, eg: OOM, "
            "invalid allocation alignments, etc.")

            "Interval (in milliseconds) at which to attempt release of unused "
            "memory to the OS. Negative values disable the feature.")
