Updates the afalg hash driver to support the new accumulative
hashing changes as part of the patch series.
Implements opening/closing of contexts, updating hash data
and finalizing the hash digest.
In order to support the update function, a flag needs to be passed
to the kernel via the socket send call (MSG_MORE) to notify it that more
data is to be expected to calculate the hash correctly.
As a result, a new function was added to the iov helper utils to allow
passing a flag to the socket send call.
