Create replacement header files inside openbsd-compat for common headers
that are missing on a given platform. Usually these are just empty,
but in some cases they'll include the equivalent file. This avoids
having to wrap those includes in '#ifdef HAVE_FOO_H' and reduces the
diff vs OpenBSD.
If we create any such headers, add the path to includes.
Initially just stdint.h, more to follow.

The PKCS#11 code in OpenSSH used the libcrypto public key method API
(e.g. the delightfully named RSA_meth_free()) to delegate signing
operations to external keys. This had one advantage - that it was
basically transparent to callers, but also had a big disadvantage -
that we'd manually have to track the method implementations, their
state and their relationships to the underlying PKCS#11 objects.
This rips this out and replaces it with explicit delegation to
PKCS#11 code for externally hosted keys via the ssh-pkcs11-helper
subprocess. This is very similar to how we handle FIDO keys in
OpenSSH (i.e. via ssh-sk-helper). All we need to track now is a
much simpler mapping of public key -> helper subprocess.
Kicking our libcrypto meth dependency also makes it much easier
to support Ed25519 keys in PKCS#11, which will happen in a subsequent
commit.

While freezero() returns early if the pointer is NULL the tests for
NULL in callers are left to avoid warnings about passing an
uninitialised size argument across a function boundry.

New key API: refactor key-related functions to be more library-like,
existing API is offered as a set of wrappers.

New buffer API; the first installment of the conversion/replacement
of OpenSSH's internals to make them usable as a standalone library.
This includes a set of wrappers to make it compatible with the
existing buffer API so replacement can occur incrementally.
