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.

At other places, we already use __BYTE_ORDER define to detect endianness.
We don't need multiple mechanisms.
Also note that meson did not do the correct thing as AC_C_BIGENDIAN,
so meson + nss + big-endian was possibly broken.
We need to (and already did) define our own identifier for ciphers,
because the gnutls/nss identifiers must be abstracted.
Don't use a string for that. The number of supported ciphers
is not generic but fixed and known at compiler time. An enum
is better suited.
- avoid "const gsize" as type for function arguments.
- consistently use "guint8 *" type for binary data, instead
of "char *", which indicates a NUL terminated C string.
- drop nm_crypto_encrypt(). It's not actually used outside of
"nm-crypto.c".
- rename internal _nm_crypto_*() functions that are only used
in tests. It's so much nicer to visually recognize functions
that are used for testing only.
Rename _nm_crypto_verify_cert() to _nm_crypto_verify_x509().
Also, don't let it return a NMCryptoFileFormat result. This
function only checks for a particular format, hence it
should only return true/false.
Also, fix setting error output argument when the function fails.
Follow our convention, that items in headers are all named with
an "NM" prefix.
Also, "nm-crypto-impl.h" contains internal functions that are to be implemented
by the corresponding crypto backends. Distinguish their names as well.
There are two aspects: the public crypto API that is provided by
"nm-crypto.h" header, and the internal header which crypto backends
need to implement. Split them.
