costan 89af27bde5 Remove ssize_t from code that is not POSIX-specific. ssize_t is not standard C++. It is a POSIX extension. Therefore, it does not belong in generic code. This change tweaks the logic in DBIter to remove the need for signed integers, so ssize_t can be replaced with size_t. The impacted method and private member are renamed to better express their purpose. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=211471606		vor 6 Jahren
