Linux ktls sendfile

This commit introduces support for Linux KTLS sendfile.
Sendfile semantics require the use of a kernel TLS socket to construct the TLS

KTLS sendfile improves performance by avoiding the copy of file data into user

Via the FIPS lab, NIST confirmed:

    The CMVP had a chance to discuss this inquiry and we agree that
    hashing the NDRNG block does meet the spirit and letter of AS09.42.

    However, the CMVP did have a few questions: what hash algorithm would
    be used in this application? Is it approved? Is it CAVs tested?

SHA256 is being used here and it will be both approved and CAVs tested.

This means that no raw entropy needs to be kept between RNG seedings, preventing
a potential attack vector aganst the randomness source and the DRBG chains.

asn1parse: avoid double free

|str| was used for multiple conflicting purposes.  When using
'-strictpem', it's used to uniquely hold a reference to the loaded
payload.  However, when using '-strparse', |str| was re-used to hold
the position from where to start parsing.

So when '-strparse' and '-strictpem' are were together, |str| ended up
pointing into data pointed at by |at|, and was yet being freed, with
the result that the payload it held a reference to became a memory
leak, and there was a double free conflict when both |str| and |at|
were being freed.

The situation is resolved by always having |buf| hold the pointer to
the file data, and always and only use |str| to hold the position to
start parsing from.  Now, we only need to free |buf| properly and not
|str|.

Fix calling convention bug in ecp_nistz256_ord_sqr_mont

The rep parameter takes an int in C, but the assembly implementation
looks at the upper bits. While it's unlikely to happen here, where all
calls pass a constant, in other scenarios x86_64 compilers will leave
arbitrary values in the upper half.

Fix this by making the C prototype match the assembly. (This aspect of
the calling convention implies smaller-than-word arguments in assembly
functions should be avoided. There are far fewer things to test if
everything consistently takes word-sized arguments.)

Separate the lookup test

This fixes the "verifying the alias" case.
Actually, while working on it, I realized that conceptually we were
testing the 2 different behaviours of `EC_GROUP_check_named_curve()` at
the same time, and actually not in the proper way.

I think it's fair to assume that overwriting the curve name for an
existing group with `NID_undef` could lead to the unexpected behaviour
we were observing and working around.
Thus I decided to separate the lookup test in a dedicated simpler test
that does what the documentation of `EC_GROUP_check_named_curve()`
suggests: the lookup functionality is meant to find a name for a group
generated with explicit parameters.

In case an alternative alias is returned by the lookup instead of the
expected nid, to avoid doing comparisons between `EC_GROUP`s with
different `EC_METHOD`s, the workaround is to retrieve the `ECPARAMETERS`
of the "alias group" and create a new explicit parameters group to use
in `EC_GROUP_cmp()`.
