ARROW-7943: [C++][Parquet] Add code to generate rep/def levels for nested arrays There will be follow-up code to integrate this with the higher level writers. This takes a slightly more OO approach then LevelBuilder in writer.cc and also attempts to do more batching at each level when possible. No benchmarks have been run yet. There are likely a lot of typos given the hours that I've been working on it (but hopefully no logic bugs). I'm sorry. Also allow TypedBufferBuilder/BufferBuilder to take an initial ResizableBuffer to use so scratch can easily be reused. Closes #6490 from emkornfield/paths and squashes the following commits: 4c6892d0c <Wes McKinney> export symbols 23e6bfc52 <Wes McKinney> int16_t->int64_t 387adc85b <Wes McKinney> iwyu 3fc9e5cb2 <Wes McKinney> Simplify schema statements in tests.
