We only needed proper glib enum types for having properties
and signal arguments. These got all converted to plain int,
so no longer generate such an enum type.
Had to rename "nm-enum-types.h" because it works badly with
"libnm/nm-enum-types.h". Maybe I could fix that differently,
but duplicate names is anyway error prone.
Note that "nm-core-enum-types.h" is already taken too, so
"nm-src-enum-types.h" it is.
... and make the structs NMAuthSubject and NMAuthSubjectClass
opaque types.
I don't want to do this for all our types, only for a few prominent
GObject instances that we create a lot and that are really not expected
to ever be subclassed.
NMAuthSubject is such a candidate. It is really a very simple object
containing a few information bits about the authentication request.
It is not ever expected to be extended/inherited or become more
complex. No need to do a full-fledged private-data implementation.
When mounting /proc with hidepid, we might fail to read the
start-time of the process from /proc/$PID/stat. In this case,
we should just accept a start-time of zero.
On the other side of authentication, polkit should accept a zero
start-time too.
nm_utils_get_start_time_for_pid() has other uses in NetworkManager,
mostly when killing a process from a PIDFILE or during
nm_utils_kill_process_sync(). In both these cases, this will only
succeed if we try to kill a process that also runs a root.
For processes started by the current instance, we don't care about the
PIDFILE and use nm_utils_kill_child_?sync() -- so there is no problem
with hidepid there.

- 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
Port remaining bits to gdbus and remove stray dbus-glib references
Drop the dbus-glib version check from configure, since nothing depends
on new dbus-glib any more.
Move nm-dbus-glib-types.h and nm-gvaluearray-compat.h from include/ to
libnm-util/ since they are now only used by libnm-util and libnm-glib.
Our gdbus generated types use the same names as their corresponding
"real" types, but with "NM" changed to "NMDBus".
Unfortunately, that means that introspection/nmdbus-manager.c (the
generated type for src/nm-manager.c) uses the same type name as the
entirely unrelated src/nm-dbus-manager.c.
Fix this by removing the "d" from src/nm-dbus-manager.c. (We could
rename the generated type instead, but then it becomes inconsistent
with all the other generated types, and we're already using it as
"NMDBusManager" in libnm/nm-manager.c.)
Rather than randomly including one or more of <glib.h>,
<glib-object.h>, and <gio/gio.h> everywhere (and forgetting to include
"nm-glib-compat.h" most of the time), rename nm-glib-compat.h to
nm-glib.h, include <gio/gio.h> from there, and then change all .c
files in NM to include "nm-glib.h" rather than including the glib
headers directly.
(Public headers files still have to include the real glib headers,
since nm-glib.h isn't installed...)
Also, remove glib includes from header files that are already
including a base object header file (which must itself already include
the glib headers).
kill(pid,sig) can return success for zombie processes. This
caused nm_utils_kill_process_sync() to hang indefinitely.
Fix it by also checking the process state.
config.h should be included from every .c file, and it should be
included before any other include. Fix that.
(As a side effect of how I did this, this also changes us to
consistently use "config.h" rather than <config.h>. To the extent that
it matters [which is not much], quotes are more correct anyway, since
we're talking about a file in our own build tree, not a system
include.)
Let the user completly disable polkit authentication by
building NM with configure option '--enable-polkit=disabled'.
In that case, configuring 'main.auth-polkit=yes' will fail all
authentication requests (except root-requests, which are always granted).
This reduces the size of the NetworkManager binary by some 26KB (16KB
stripped).

This makes NetworkManager independent of <polkit/polkit.h>
development headers and libpolkit-gobject-1.so library.
Instead communicate directly with polkit using its DBUS
interface.
PolicyKit support is now always compiled in. You can control
polkit authorization with the configuration option
[main]
auth-polkit=yes|no
If the configure option is omitted, a build time default
value is used. This default value can be set with the
configure option --enable-polkit.
This commit adds a new class NMAuthManager that reimplements the
relevant DBUS client parts. It takes source code from the polkit
library.

When an activation request requires secrets, if there is a secret
agent in the process that made the request, then prefer that to all
other secret agents.
