Cover letter [PATCH 0/3 v3] chunkd on-disk checksumming

Changes from v2:
- Do not drop sendfile(2). Instead, make sendfile(2) work with new file format (checksum table in each on-disk file).

We will turn off sendfile(2) only for ranged GET requests.

Non-SSL, whole-object GET requests can still use sendfile(2).

Patches are against hail.git commit 68f68e3630cae4bb2ca651b577c1d4d0292687b1.
