From the files under "shared/nm-utils" we build an internal library
that provides glib-based helper utilities.
Move the files of that basic library to a new subdirectory
"shared/nm-glib-aux" and rename the helper library "libnm-core-base.la"
to "libnm-glib-aux.la".
Reasons:
- the name "utils" is overused in our code-base. Everything's an
"utils". Give this thing a more distinct name.
- there were additional files under "shared/nm-utils", which are not
part of this internal library "libnm-utils-base.la". All the files
that are part of this library should be together in the same
directory, but files that are not, should not be there.
- the new name should better convey what this library is and what is isn't:
it's a set of utilities and helper functions that extend glib with
funcitonality that we commonly need.
There are still some files left under "shared/nm-utils". They have less
a unifying propose to be in their own directory, so I leave them there
for now. But at least they are separate from "shared/nm-glib-aux",
which has a very clear purpose.

A NetworkManager client requires an API to validate and decode
a base64 secret -- like it is used by WireGuard. If we don't have
this as part of the API, it's inconvenient. Expose it.
Rename it from _nm_utils_wireguard_decode_key(), to give it a more
general name.
Also, rename _nm_utils_wireguard_normalize_key() to
nm_utils_base64secret_normalize(). But this one we keep as internal
API. The user will care more about validating and decoding the base64
key. To convert the key back to base64, we don't need a public API in
libnm.
This is another ABI change since 1.16-rc1.

That is slightly complex, because we need to (DNS) resolve the endpoints,
and we also have to retry periodically. For example, initially we may be
unable to resolve an endpoint, but later we may be.
What is also interesting is that during assume and reapply, we may not
have all information in the profile. Most notably, the private keys will
be missing. We need to cope with that and not reconfigure keys. However,
we still need to resolve names and update the endpoints.
For now only add the core settings, no peers' data.
To support peers and the allowed-ips of the peers is more complicated
and will be done later. It's more complicated because these are nested
lists (allowed-ips) inside a list (peers). That is quite unusual and to
conveniently support that in D-Bus API, in keyfile format, in libnm,
and nmcli, is a effort.
Also, it's further complicated by the fact that each peer has a secret (the
preshared-key). Thus we probably need secret flags for each peer, which
is a novelty as well (until now we require a fixed set of secrets per
profile that is well known).
