This reduces the amount of glue code, because we don't need a void
pointer or vtable within the structure.
The only snag is that reftable_index_record contain a strbuf, so it
cannot be zero-initialized. To address this, use reftable_new_record()
to return fresh instance, given a record type. Since
reftable_new_record() doesn't cause heap allocation anymore, it should
be balanced with reftable_record_release() rather than
reftable_record_destroy().
Thanks to Peff for the suggestion.

reftable: read reftable files2021-10-08T17:45:48ZHan-Wen Nienhuyshanwen@google.com2021-10-07T20:25:08Zurn:sha1:46bc0e731a70716485bc3c8bdaf7e6e6f88073a9
This supports reading a single reftable file.
The commit introduces an abstract iterator type, which captures the usecases
both of reading individual refs, and iterating over a segment of the ref
namespace.
