Will 6b16dafb4d Add metadata_max and inline_file_max to config ...

We have seen poor read performance on NAND flashes with 128kB blocks.
The root cause is inline files having to traverse many sets of metadata
pairs inside the current block before being fully reconstructed. Simply
disabling inline files is not enough, as the metadata will still fill up
the block and eventually need to be compacted.

By allowing configuration of how much size metadata takes up, along with
limiting (or disabling) inline file size, we achieve read performance
improvements on an order of magnitude.
