Subject: [PATCH 1/2] ghmac: Split off wrapper functions into ghmac-utils.c
Prep for adding a GnuTLS HMAC implementation; these are just
utility functions that call the "core" API.

Subject: [PATCH 2/2] Add a gnutls backend for GHmac
For RHEL we want apps to use FIPS-certified crypto libraries,
and HMAC apparently counts as "keyed" and hence needs to
be validated.
Bug: https://bugzilla.redhat.com/show_bug.cgi?id=1630260
Replaces: https://gitlab.gnome.org/GNOME/glib/merge_requests/897
This is a build-time option that backs the GHmac API with GnuTLS.
Most distributors ship glib-networking built with GnuTLS, and
most apps use glib-networking, so this isn't a net-new library
in most cases.
However, a fun wrinkle is that the GnuTLS HMAC API doesn't expose
the necessary bits to implement `g_hmac_copy()`; OpenSSL does.
I chose to just make that abort for now since I didn't find
apps using it.
