The reftable library aborts with a bug in case `reftable_record_cmp()` is invoked with two records of differing types. This would cause the program to die without the caller being able to handle the error, which is not something we want in the context of library code. And it ties us to the Git codebase. Refactor the code such that `reftable_record_cmp()` returns an error code separate from the actual comparison result. This requires us to also adapt some callers up the callchain in a similar fashion. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
