[PATCH 3/9] reftable/block: better grouping of functions

[Patrick Steinhardt <ps@pks.im>]

[-- Attachment #1: Type: text/plain, Size: 4026 bytes --]

Function definitions and declaration of `struct block_reader` and
`struct block_iter` are somewhat mixed up, making it hard to see which
functions belong together. Rearrange them.
