ebc610e5bc [CRYPTO] templates: Pass type/mask when creating instances
This patch passes the type/mask along when constructing instances of
templates.  This is in preparation for templates that may support
multiple types of instances depending on what is requested.  For example,
the planned software async crypto driver will use this construct.

For the moment this allows us to check whether the instance constructed
is of the correct type and avoid returning success if the type does not
match.

73af07de3e [CRYPTO] hmac: Fix error truncation by unlikely()
The error return values are truncated by unlikely so we need to
save it first.  Thanks to Kyle Moffett for spotting this.

5f77043f0f [CRYPTO] hmac: Fix hmac_init update call
The crypto_hash_update call in hmac_init gave the number 1
instead of the length of the sg list in bytes.  This is a
missed conversion from the digest => hash change.

As tcrypt only tests crypto_hash_digest it didn't catch this.

8425165dfe [CRYPTO] digest: Remove old HMAC implementation
This patch removes the old HMAC implementation now that nobody uses it
anymore.

0796ae061e [CRYPTO] hmac: Add crypto template implementation
This patch rewrites HMAC as a crypto template.  This means that HMAC is no
longer a hard-coded part of the API.  It's now a template that generates
standard digest algorithms like any other.

The old HMAC is preserved until all current users are converted.

The same structure can be used by other MACs such as AES-XCBC-MAC.

055bcee310 [CRYPTO] digest: Added user API for new hash type
The existing digest user interface is inadequate for support asynchronous
operations.  For one it doesn't return a value to indicate success or
failure, nor does it take a per-operation descriptor which is essential
for the issuing of requests while other requests are still outstanding.

This patch is the first in a series of steps to remodel the interface
for asynchronous operations.

For the ease of transition the new interface will be known as "hash"
while the old one will remain as "digest".

This patch also changes sg_next to allow chaining.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
