- All internal source files (except "examples", which are not internal)
should include "config.h" first. As also all internal source
files should include "nm-default.h", let "config.h" be included
by "nm-default.h" and include "nm-default.h" as first in every
source file.
We already wanted to include "nm-default.h" before other headers
because it might contains some fixes (like "nm-glib.h" compatibility)
that is required first.
- After including "nm-default.h", we optinally allow for including the
corresponding header file for the source file at hand. The idea
is to ensure that each header file is self contained.
- Don't include "config.h" or "nm-default.h" in any header file
(except "nm-sd-adapt.h"). Public headers anyway must not include
these headers, and internal headers are never included after
"nm-default.h", as of the first previous point.
- Include all internal headers with quotes instead of angle brackets.
In practice it doesn't matter, because in our public headers we must
include other headers with angle brackets. As we use our public
headers also to compile our interal source files, effectively the
result must be the same. Still do it for consistency.
- Except for <config.h> itself. Include it with angle brackets as suggested by
https://www.gnu.org/software/autoconf/manual/autoconf.html#Configuration-Headers
- "gsystem-local-alloc.h" and <gio/gio.h> are already included via
"nm-default.h". No need to include them separately.
- include "nm-macros-internal.h" via "nm-default.h" and drop all
explict includes.
- in the modified files, ensure that we always include "config.h"
and "nm-default.h" first. As second, include the header file
for the current source file (if applicable). Then follow external
includes and finally internal nm includes.
- include nm headers inside source code files with quotes
- internal header files don't need to include default headers.
They can savely assume that "nm-default.h" is already included
and with it glib, nm-glib.h, nm-macros-internal.h, etc.
VPN plugins are usually split into different packages. It might
be that the plugin file is simply not installed. We want the caller
to be able to recognize that conditation to fail gracefully.
Thus return a certain error code.
Originally, nm-applet loaded the vpn plugins by passing the filename
to g_module_open(). Thereby, g_module_open() allowed for missing file
extension and tries to complete the name with a system-dependent suffix.
When porting to libnm, we kept that behavior but did more elaborate
checks on the file, like checking owner and permissions.
Change to no longer trying to append the system suffix, but require
an exact path. That is no usability problem, because the plugin path
is specified in the .name files, and we just require them now to be the
full path (including the .so extension).
Note also, that this only affects new, libnm-based vpn plugins, thus there
is no change in behavior for legacy libnm-glib based plugins.

The localization headers are now included via "nm-default.h".
Also fixes several places, where we wrongly included <glib/gi18n-lib.h>
instead of <glib/gi18n.h>. For example under "clients/" directory.
Split the content of libnm/nm-vpn-editor-plugin.h and
move NMVpnEditorPlugin to libnm-core/nm-vpn-editor-plugin.h.
VPN plugins allow us to extend functionality about VPNs.
This can be also useful for NetworkManager core, hence
move that part to libnm-core.
The name NMVpnEditorPlugin is slightly misleading but not completely
wrong. The "editor" part stands no longer for bringing nm-applet
functionality (alone), but enable general VPN functionality in
the client.
Especially because we already have NMVpnPluginOld with a different
meaning (i.e. a base class of the plugin server implementation).
