d984b2ce4a shared: move most of "shared/nm-utils" to "shared/nm-glib-aux"
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.

e1c7a2b5d0 all: don't use gchar/gshort/gint/glong but C types
We commonly don't use the glib typedefs for char/short/int/long,
but their C types directly.

    $ git grep '\<g\(char\|short\|int\|long\|float\|double\)\>' | wc -l
    587
    $ git grep '\<\(char\|short\|int\|long\|float\|double\)\>' | wc -l
    21114

One could argue that using the glib typedefs is preferable in
public API (of our glib based libnm library) or where it clearly
is related to glib, like during

  g_object_set (obj, PROPERTY, (gint) value, NULL);

However, that argument does not seem strong, because in practice we don't
follow that argument today, and seldomly use the glib typedefs.
Also, the style guide for this would be hard to formalize, because
"using them where clearly related to a glib" is a very loose suggestion.

Also note that glib typedefs will always just be typedefs of the
underlying C types. There is no danger of glib changing the meaning
of these typedefs (because that would be a major API break of glib).

A simple style guide is instead: don't use these typedefs.

No manual actions, I only ran the bash script:

  FILES=($(git ls-files '*.[hc]'))
  sed -i \
      -e 's/\<g\(char\|short\|int\|long\|float\|double\)\>\( [^ ]\)/\1\2/g' \
      -e 's/\<g\(char\|short\|int\|long\|float\|double\)\>  /\1   /g' \
      -e 's/\<g\(char\|short\|int\|long\|float\|double\)\>/\1/g' \
      "${FILES[@]}"

54356ac8c7 shared: don't use nm_str_hash() in "nm-enum-utils.c"
This was only used for some extra assertions. It' is not essential.
If this would be for real usage, we should add a dependancy so that
nm-utils/nm-enum-utils.c requires nm-hash-utils.h. But as it is,
this is not necessary.

This fixes build for meson, which wrongly tries to build nm-enum-utils.c
for libnm-util, but then fails to include nm-hash-utils.c. That should
be fixed independently.

84a6eff106 shared: don't allow aliases re-numbering in _nm_utils_enum_from_str_full()
For _nm_utils_enum_to_str_full(), we always first look whether we have
an alias/nick for the numeric value, and preferably use that. That makes a
lot of sense, as it allows the caller to provide better names (aliases),
which are preferred over the name from the GLib type. It renames the
numeric value.

For the reverse conversion, this makes less sense. A name should have a
unique numeric value. That is, we should not use one name that maps to
a different numeric value based on value_infos and GLib type. IOW, we
should not re-number names.

Add an assertion that we don't provide such a value_infos parameter,
that conflicts with names from GLib type.

Also, although the case where GLib type and value_infos disagree is now
forbidden by an assert, reorder the statements in _nm_utils_enum_from_str_full()
too. There is no difference in practice, but it mirros what we do in the
to-str case.

3021a8cf6b shared/trivial: rename local variable class
There is no real problem with using "class" in C. However, it would
be a keyword in C++. Just avoid it, and use "klass" instead.

9800b1dccc libnm: move public nm_utils_enum_*() functions back to libnm-core
Commit a8730c51c8 moved the enum
utils from libnm-core to shared/nm-utils.

However, three of those functions are part of public API in libnm.
So, when statically linking against "shared/nm-utils/nm-enum-utils.c"
and dynamically linking against libnm.so, those symbols are present
twice and cause a linker failure.

Fix that by moving the public API back to libnm-core.

a8730c51c8 libnm: move enum utils to new shared file shared/nm-utils/nm-enum-utils.h
libnm contains the public function nm_utils_enum_from_str() et al.
The function is not flexible enough for nmcli's usecase. So, I would
need another public function like nm_utils_enum_from_str_full() that
has an extended API.

That was already required previously for ifcfg-rh writer, but in that
case I could just add it as internal API as libnm-core is linked statically
with NetworkManager.

I don't want to commit to a public API for an utility function. So move
the code instead to the shared directory, so that nmcli may link
statically against it and use the internal API.
