Rename the DEFAULT_SIZE macro to VECTOR_DEFAULT_SIZE and hard-code the size value (10) in the macro rather than use a (-1) flag. This makes room for the 'Vector.size' member to migrate to an unsigned type. Signed-off-by: Kang-Che Sung <explorer09@gmail.com>
Use a goto label when a table row should be removed. No changes to code behavior.
Remove the 'dirty_index' and 'dirty_count' members of Vector object. Instead, let the callers of the Vector_softRemove() operation track the 'dirtyIndex' and pass it to Vector_compact() when needed. (The new 'dirtyIndex' local variables are safe to migrate from 'int' to 'size_t' because no negative value is used.) 'dirty_index' is supposed to have shorter lifespan than a Vector instance, and by removing the member we can reduce object size. 'dirty_count' is redundant and thus removed as well. A boolean 'isDirty' member is added to a Vector object for ease of debugging. Signed-off-by: Kang-Che Sung <explorer09@gmail.com>

This frees up the need of
dirty_indexanddirty_countmembers ofVectorobject. These two members are not supposed to last long and are only useful in keeping the state between thesoftRemove()andcompact()operations.Rework the two operations so that the caller would keep the
dirtyIndexwhen callingsoftRemove()and passdirtyIndexto thecompact()in the final step.The new
dirtyIndexis safe to migrate to usingsize_tas I don't use any negative value of it.
