7e68d7f61a libseckey: Adjustments for OpenSSL v4.0.0 API changes and deprecations
With OpenSSL 4.0.0 function X509_NAME_get_entry() returns a const pointer.
Make the local variable also const to avoid compile warnings like:

  warning: assignment discards ‘const’ qualifier from pointer target type
  [-Wdiscarded-qualifiers]

fcfd4a6158 libseckey: Fix error checking when building ECDSA signatures
OpenSSL function i2d_ECDSA_SIG() returns a negative value in case of
an error, so check the returned length for <= zero to detect an error.

e70cde2c5d libseckey: Add a secure key library
The libseckey is a secure key library to perform secure key operations
with OpenSSL. It provides a framework to create OpenSSL PKEYs with a
secure key attached. Such a PKEY contains the public key parts in clear,
but the private key as secure key blob. Only the private key operations
are actually performed with the secure key, public key operations are
performed in software by OpenSSL. It supports CCA and EP11 secure
keys for RSA and ECC crypto operations.

Because many PKEY method related functions are deprecated since OpenSSL
3.0, two versions of the OpenSSL secure key support are needed. One (using
a PKEY method override) for OpenSSL 1.1.1, and another one (using an own
OpenSSL provider) for OpenSSL 3.0 and later. The desired implementation is
selected automatically at compile time, using OpenSSL version defines. The
interface of both implementations is the same, so a user does not need to
care which one is used.
