We already have Update(), UpdateUnsaved() and Save(), which serve
similar purposes. We will need a form of update with another argument.
Most notably, to block autoconnect while doing the update.
Other use cases could be to prevent reapplying connection.zone and
connection.metered, to to reapply all changes.
Instead of adding a specific update function that only serves that
new use-case, add a extensible Update2() function. It can be extended
to cope with future variants of update.
At startup the manager tries to create virtual devices without a
specific order and spits warnings when a device can't be realized
because the parent device is not yet created. These failures are not
something the user should worry about because the creation will be
retried when the parent appears.
A better approach is to return an error code from the device's
create_and_realize() telling that it failed because the parent doesn't
exist. In this way, the manager knows that the device isn't ready and
can avoid printing warning messages.
Moving the PPP manager to a separate plugin that is loaded when needed
has the advantage of slightly reducing memory footprint and makes it
possible to install the PPP support only where needed.

Add new Reload D-Bus command to reload NetworkManager configuration.
For now, this is like sending SIGHUP to the process. There are several
advantages here:
- it is guarded via PolicyKit authentication while signals
can only be sent by root.
- the user can wait for the reload to be complete instead of sending
an asynchronous signal. For now, we operation completes after
nm_config_reload() returns, but later we could delay the response
further until specific parts are fully reloaded.
- SIGHUP reloads everything including re-reading configuration from
disk while SIGUSR1 reloads just certain parts such as writing out DNS
configuration anew.
Now, the Reload command has a flags argument which is more granular
in selecting parts which are to be reloaded. For example, via
signals the user can:
1) send SIGUSR1: this writes out the DNS configuration to
resolv.conf and possibly reloads other parts without
re-reading configuration and without restarting the DNS plugin.
2) send SIGHUP: this reloads configuration from disk,
writes out resolv.conf and restarts the DNS plugin.
There is no way, to only restart the DNS plugin without also reloading
everything else.
This breaks API and ABI for the functions related to Reapply,
which got introduced in the current 1.1 development phase.
The version-id is here to allow users to error out if the connection
on the device was changed by a concurrent action.

Update the docs build to include and exclude the correct files.
Fill in some missing documentation, and fix problems in the existing
docs. (In particular, "<" can't appear as a literal in documentation,
so change it to "<". Also, "PKCS#12" has to be written as
"PKCS#<!-- -->12", or gtk-doc will think "#12" is a reference to a
type named "12".)
Move the definition of NMVpnPluginError to nm-errors and register it
with D-Bus. Rename GENERAL to FAILED, and CONNECTION_INVALID to
INVALID_CONNECTION, for consistency.
(As with the NMSecretAgentError renamings, the renaming here is not an
ABI break, because the daemon currently never checks for any specific
error codes other than INTERACTIVE_NOT_SUPPORTED.)
Move the definition of NMSecretAgentError to nm-errors, register it
with D-Bus, and verify in the tests that it maps correctly.
NM_SECRET_AGENT_ERROR_INTERNAL_ERROR is renamed to
NM_SECRET_AGENT_ERROR_FAILED, and NM_SECRET_AGENT_ERROR_NOT_AUTHORIZED
to NM_SECRET_AGENT_ERROR_PERMISSION_DENIED, for consistency with other
error domains. While NMSecretAgentError, unlike most other error
domains, has always been correctly mapped across D-Bus, the renaming
is not an ABI break, because the daemon never checks for either of
those values, so all versions of the daemon will treat
"org.freedesktop.NetworkManager.SecretAgent.InternalError" and
"org.freedesktop.NetworkManager.SecretAgent.Failed" the same (by just
ignoring the error name and keeping only the error message).
Move the definition of NMSettingsError to nm-errors, register it with
D-Bus, and verify in the tests that it maps correctly.
Remove a few unused error codes, simplify a few others, and rename
GENERAL to FAILED and HOSTNAME_INVALID to INVALID_HOSTNAME, for
consistency.
NMManagerError has other operation-specific errors (like
NM_MANAGER_ERROR_ALREADY_ASLEEP_OR_AWAKE), so it makes sense to move
NM_LOGGING_ERROR_UNKNOWN_LEVEL and NM_LOGGING_ERROR_UNKNOWN_DOMAIN
there too rather than having them in their own tiny error domain.
Move the definition of NMManagerError to nm-errors, register it with
D-Bus, and verify in the tests that it maps correctly.
NM_MANAGER_ERROR_INTERNAL gets renamed to NM_MANAGER_ERROR_FAILED for
consistency. NM_MANAGER_ERROR_UNMANAGED_DEVICE is dropped since that
name doesn't really describe the one place it was previously used in.
NM_MANAGER_ERROR_SYSTEM_CONNECTION is dropped because it was't being
used. NM_MANAGER_ERROR_UNSUPPORTED_CONNECTION_TYPE is dropped because
it can be replaced with an NM_CONNECTION_ERROR.
NM_MANAGER_ERROR_AUTOCONNECT_NOT_ALLOWED is turned into the more
generic NM_MANAGER_ERROR_CONNECTION_NOT_AVAILABLE.
Also, remove the <tp:possible-errors> sections from nm-manager.xml,
since they were completely out of date.
Most NMDevice types defined their own error domain but then never used
it. A few did use their errors, but some of those errors are redundant
with NMDeviceError, and others can be added to it.
Merge libnm's NMDeviceError and the daemon's NMDeviceError into a
single enum (in nm-errors.h). Register the domain with D-Bus, and add
a test that the client side decodes it correctly.
The daemon's NM_DEVICE_ERROR_CONNECTION_INVALID gets absorbed into
libnm's NM_DEVICE_ERROR_INVALID_CONNECTION, and
NM_DEVICE_ERROR_UNSUPPORTED_DEVICE_TYPE gets dropped, since it was
only returned from one place, which is now using
NM_DEVICE_ERROR_FAILED, since (a) it ought to be a "can't happen", and
(b) the only caller of that function just logs error->message and then
frees the error without ever looking at the code.
Register NMConnectionError with D-Bus on both sides, so that, eg,
connection validation failures in the daemon will translate to the
correct error codes in the client.
Add nm-errors.[ch], and move libnm-core's two error domains
(NMConnectionError and NMCryptoError) there.
NMCryptoError wasn't previously visible, but it can be returned from
some public API, so it should be.
