WIP tool to rewrite cfiles

Adds a tool to rewrite cfiles while skipping cblocks that have been
corrupted. This cannot be the final solution, since any positional
indexing on the CFile is ruined due to the skipped cblocks, but it's a
start.

Nullable and key CFiles are not supported.

Example:
$ kudu file rewrite_cfile src_cfile dst_cfile

WIP: in skipping corrupted blocks, we're not doing some accounting of
last_prepared_idx_, leading to a DCHECK failure, though I think this
works as expected for a healthy block.

not sure quite how useful this will be with automated CFile checksum error handling
