Mutil 1.76.5 release fixed

The Mutil 1.76.5 release had the wrong coreutils-7.6 patch (was still the patch for Mutil 1.76.4). The 1.76.5 patch was improperly named coreutil-7.6 (without an "s"). The release is now fixed to contain the correctly named files.

Mutil 1.76.3 released

- Added note about need for static version of libgpg-error
- Hash of stdin (i.e. piped input and file name "-") now works in msum
- Hash output format of mcp now exactly matches msum
- Added --check-tree option to isolate corruption
- Added --offset and --length options to mcp to copy specific portion
- Added file restriping to mcp based on file size for Lustre targets
- Added --print-stripe to mcp to print striping changes to stderr
- Fixed divide by 0 when hash leaf size is 0 due to default split size
- Changed hash output so non-standard output is reported in comments
- Now adjust split size to buffer size when 0 < split size < buffer size
- Fixed making of holes in mcp in double buffer case
- Split --fadvise into --fadvise-read and --fadvise-write
- Added --skip-chmod to mcp to retain temporary permissions used during copy
- Fixed --direct-read errors on some file systems due to last unaligned read
