pg_combinebackup had various problems: * strncpy was used in various places where strlcpy should be used instead, to avoid any possibility of the result not being \0-terminated. * scan_for_existing_tablespaces() failed to close the directory, and an error when opening the directory was reported with the wrong pathname. * write_reconstructed_file() contained some redundant and therefore dead code. * flush_manifest() didn't check the result of pg_checksum_update() as we do in other places, and misused a local pathname variable that shouldn't exist at all. In pg_basebackup, the wrong variable name was used in one place, due to a copy and paste that was not properly adjusted. In blkreftable.c, the loop incorrectly doubled chunkno instead of max_chunks. Fix that. Also remove a nearby assertion per repeated off-list complaints from Tom Lane. Per Coverity and subsequent code inspection by me and by Tom Lane.
