Sunil Thaha	a484a83d4a	fix: panic when checkpoint directory is empty (#9687 ) Calling `wal.NewSegmentBufReader()` without any segments would cause a `panic` resulting in prometheus crashing. This patch fixes the panic by making segmentBufReader return a EOF if there are not segments. This also means an empty checkpoint directory which should never be the case unless it has been tampered with (or has issues due to the underlying filesystem e.g. NFS) would be ignored by Prometheus and would continue to run instead of the current behaviour which is to panic.

Chris Marchbanks	7c7dafc321	Do not snappy encode if record is too large (#8790 ) Snappy cannot encode records larger than ~3.7 GB and will panic if an encoding is attempted. Check to make sure that the record is smaller than this before encoding. In the future, we could improve this behavior to still compress large records (or break them up into smaller records), but this avoids the panic for users with very large single scrape targets.

Chris Marchbanks	bedcd88343	Compress records before checking segment size (#8501 ) Right now a new segment might be created unnecessarily if the uncompressed record would not fit, but after compression (typically reducing record size in half) it would.
