util.dbuffer: dynamic string buffer
Similar to util.ringbuffer (and shares almost identical API). Differences:
- size limit is optional and dynamic
- does not allocate a fixed buffer of max_size bytes
- focus on simply storing references to existing string objects where possible,
avoiding unnecessary allocations
- references are still stored in a ring buffer to enable use as a fast FIFO
Optional second parameter to new() provides the number of ring buffer segments. On
Lua 5.2 on my laptop, a segment is ~19 bytes. If the ring buffer fills up, the next
write will compact all strings into a single item.
