crypto: Make QCryptoTLSCreds* structures private

Code consuming the "crypto/tlscreds*.h" APIs doesn't need
to access its internals. Move the structure definitions to
the "tlscredspriv.h" private header (only accessible by
implementations). The public headers (in include/) still
forward-declare the structures typedef.

Note, tlscreds.c and 3 of the 5 modified source files already
include "tlscredspriv.h", so only add it to tls-cipher-suites.c
and tlssession.c.

Removing the internals from the public header solves a bug
introduced by commit 7de2e856533 ("yank: Unregister function
when using TLS migration") which made migration/qemu-file-channel.c
include "io/channel-tls.h", itself sometime depends on GNUTLS,
leading to a build failure on OSX:

crypto: introduce new base module for TLS credentials

Introduce a QCryptoTLSCreds class to act as the base class for
storing TLS credentials. This will be later subclassed to provide
handling of anonymous and x509 credential types. The subclasses
will be user creatable objects, so instances can be created &
deleted via 'object-add' and 'object-del' QMP commands respectively,
or via the -object command line arg.

If the credentials cannot be initialized an error will be reported
as a QMP reply, or on stderr respectively.

The idea is to make it possible to represent and manage TLS
credentials independently of the network service that is using
them. This will enable multiple services to use the same set of
credentials and minimize code duplication. A later patch will
convert the current VNC server TLS code over to use this object.

The representation of credentials will be functionally equivalent
to that currently implemented in the VNC server with one exception.
The new code has the ability to (optionally) load a pre-generated
set of diffie-hellman parameters, if the file dh-params.pem exists,
whereas the current VNC server will always generate them on startup.
This is beneficial for admins who wish to avoid the (small) time
sink of generating DH parameters at startup and/or avoid depleting
entropy.
