When a virtual device fails, its state goes to FAIL and then
DISCONNECTED. In DISCONNECTED we call schedule_activate_check() to
schedule an auto-activation if needed. We also schudule the deletion
of the link through delete_on_deactivate_check_and_schedule(). The
auto-activation attempt fails because the link deletion unmanages the
device; as a result, the device doesn't try to auto-activate again.
To fix this:
- don't allow the device to auto-activate if the device deletion is
pending;
- check again if the device can be auto-activated after its deletion.

With LTO we get a compiler warning:

"XXX" is used for tagging parts of code that still need work before
merging a patch. If you want to highlight/mark a comment which is merged
use either "TODO" or "FIXME".
Of course, even "TODO" and "FIXME" should be avoided in favor of just
doing/fixing it. Such things tend to never be done/fixed.
nm_setting_ip4_config_get_dhcp_vendor_class_identifier() was
backported to nm-1-26 branch, and will be released as 1.26.4.
As such, on the stable branch the symbol will be placed in a
separate symbol version ("libnm_1_26_4").
To support the upgrade path from 1.26.4+ to 1.28+, we
want this symbol also present on master.

Use a macro that uses NM_CAST_STRV_CC() to cast the strv argument. Note that
NM_CAST_STRV_CC() uses C11's _Generic() to check whether the argument is
of a valid type.
Add a new `main.rc-manager=auto` setting, that favours to use
systemd-resolved (and not touch "/etc/resolv.conf" but configure
it via D-Bus), or falls back to `resolvconf`/`netconfig` binaries
if they are installed and enabled at compile time.
As final fallback use "symlink", like before.
Note that on Fedora there is no "openresolv" package ([1]). Instead, "systemd"
package provides "/usr/sbin/resolvconf" as a wrapper for systemd-resolved's
"resolvectl". On such a system the fallback to resolvconf is always
wrong, because NetworkManager should either talk to systemd-resolved
directly or not but never call "/usr/sbin/resolvconf". So, the special handling
for resolvconf and netconfig is only done if NetworkManager was build with these
applications explicitly enabled.
Note that SUSE builds NetworkManager with
--with-netconfig=yes
--with-config-dns-rc-manager-default=netconfig
and the new option won't be used there either. But of course, netconfig
already does all the right things on SUSE.

Arguably, a fixme comment isn't useful. It would be better to fix it.
On the other hand, nowadays these modes are not very popular and usually
not used. If somebody cares, please provide a patch.
glib's is{alnum,alpha,ascii,...}() functions perform the check based
on the current locale. Probably using isascii() would be fine anyway,
but add a NM version that just checks that the upper bit is zero.
The kernel of Ubuntu 16.04 doesn't support IFLA_BR_VLAN_STATS_ENABLED.
If we want to run on such old kernels (which we probably do), we need to
detect that, and act accordingly.
Add nm_platform_kernel_support_get_full() to allow fetching the support
state without setting it to the compile time default.
Also, use g_atomic_int_get() to access _nm_platform_kernel_support_state
values. We should not access static variables without synchronization.
Better get it correct in any case than fast.
With Fedora 33, LTO will be enabled by default via CFLAGS in
redhat-rpm-config ([1]).
That basically sets "CFLAGS=-flto -ffat-lto-objects".
Note that we have our own configure/meson option to enable LTO.
With "--with-lto" we set CFLAGS="-flto -flto-partition=none". This
is necessary due ([2], [3]).
So, disable Fedora's automatism, but turn on the suitable configure
option to get working LTO.
