[09/10] reftable/dump: move code into "t/helper/test-reftable.c"

Commit Message

Patrick Steinhardt Aug. 13, 2024, 6:24 a.m. UTC

The code in "reftable/dump.c" is only ever used by our test-tool to
implement the "reftable" subcommand. It also feels very unlikely that it
will ever be useful to any other potential user of the reftable library,
which makes it a weird candidate to have in the library interface.

Inline the code into "t/helper/test-reftable.c".
