Increase it in a linear way instead.
Helps reduce memory usage, especially on long, non fragmented output.

An alternative is using av_fast_realloc(), in a similar fashion as
ff_add_index_entry(), which will keep the memory usage more closely tied to the
amount of entries needed, but the amount of reallocations will be much higher,
so i don't know if the tradeof is beneficial.
