When read is called on a tarsum with a two different read sizes, specifically the second call larger than the first, the dynamic buffer does not get reallocated causing a slice read error.

Not breaking the default cipher and algorithm for calculating checksums,
but allow for using alternate block ciphers during the checksum
calculation.

If a tar were constructed with duplicate file names, then depending on
the order, it could result in same tarsum.

Tarsum now correctly closes the internal TarWriter which appends
a block of 1024 zeros to the end of the returned archive.

this is to enhance the tarsum algorithm, but _MUST_ be done in lock step
with the same for docker-registry. (PR will be cited)

don't export the exsisting TarSum struct and call the interface 'TarSum'
instead.

This introduces Versions for TarSum checksums.
Fixes: https://github.com/docker/docker/issues/7526
It preserves current functionality and abstracts the interface for
future flexibility of hashing algorithms. As a POC, the VersionDev
Tarsum does not include the mtime in the checksum calculation, and would
solve https://github.com/docker/docker/issues/7387 though this is not a
settled Version is subject to change until a version number is assigned.

This commit makes tarsum buffer allocation dynamic. This change
is required to avoid allocating memory excessively after the archive
buffering changes.
