[RFC] [PATCH 5/5] tcrypt: Test algorithms by name

[Steffen Klassert <steffen.klassert@secunet.com>]

This adds the 'alg' module parameter to be able to test an
algorithm by name. If the algorithm type is not ad-hoc
clear for a algorithm (e.g. pcrypt, cryptd) it is possilbe
to set the algorithm type with the 'type' module parameter.
