Subject: [PATCH 01/15] Support raw input data in apps/pkeyutl
Some signature algorithms require special treatment for digesting, such
as SM2. This patch adds the ability of handling raw input data in
apps/pkeyutl other than accepting only pre-hashed input data.
Beside, SM2 requries an ID string when signing or verifying a piece of data,
this patch also adds the ability for apps/pkeyutil to specify that ID
string.
