Add a "monitor-connection-files" config option, which can be set to
"false" to disable automatic reloading of connections on file change.
To go with this, add a new ReloadConnections method on
o.fd.NM.Settings that can be used to manually reload connections, and
add an nm-cli command to call it.
Some plugins may emit :new-connection or :unmanaged-specs-changed
while reading connections, so don't connect to those signals until
after the initial load_connections() (and just unconditionally emit
:unmanaged-specs-changed at that point).
In ifcfg-rh's get_unmanaged_specs(), don't bother to try to read the
connections first; if they haven't been read yet, just return NULL;
NMSettings will call it again after the connections have been read.
ifcfg-rh didn't let you unmanage an InfiniBand device by hardware
address because it was recording the hardware address with uppercase
letters, while nm_match_spec_hwaddr() required lowercase. Fix this by
making nm_match_spec_hwaddr() match case-insensitively (and remove the
manual lowercasing that several other places were doing to work around
this.)
keyfile didn't let you unmanage an InfiniBand device by hardware
address because it only accepted ARPHRD_ETHER hardware addresses. Fix
that by using nm_utils_hwaddr_valid() instead.
We don't always want to immediately write new connections to disk, to
facilitate "runtime" or "temporary" connections where an interface's
runtime config isn't backed by on-disk config. Also, just because
an interface's configuration is changed doesn't necessarily mean
that new configuration should be written to disk either.
Add D-Bus methods for adding new connections and for updating existing
connections that don't immediately save the connection to disk.
Also add infrastructure to indicate to plugins that the new connection
shouldn't be immediately saved if the connection was added with the
new method.
GObject creation cannot normally fail, except for types that implement
GInitable and take a GError in their _new() method. Some NM types
override constructor() and return NULL in some cases, but these
generally only happen in the case of programmer error (eg, failing to
set a mandatory property), and so crashing is reasonable (and most
likely inevitable anyway).
So, remove all NULL checks after calls to g_object_new() and its
myriad wrappers.

When determining the system hostname, /etc/hostname should override
/etc/sysconfig/network, so monitor both files.
When setting the hostname, set it in /etc/hostname, and delete the
/etc/sysconfig/network HOSTNAME entry if present.

Changing NM_CONTROLED from "no" to "yes" worked just the first time.
Fix that by storing unmanaged spec when interface becomes unmanaged
and adjust condition identifying "no-change" updates to the ifcfg
file.
When a connection changes on-disk, the in-memory copy of it may contain
transient secrets (agent-owned or not saved) that dont' get written out
to disk. When comparing the on-disk copy to the in-memory copy make sure
transient secrets are ignored so that we don't re-read the on-disk copy
needlessly.
The signal was emitted in case the removed connection was managed instead of
for unmanaged connection. Thus the signal had no effect.
That caused incorrect behaviour in case of changing NM_CONTROLLED=no to yes.
That didn't enable the device; only after the file was changed for the second time.
