This adds service discovery via SDP and RFCOMM tty management to
NetworkManager, as it was dropped from Bluez.
Based on work by Dan Williams <dcbw@redhat.com>.
The SDP discovery is based on code from Bluez project.
We'll need it for bluez5 DUN support.
[lkundrak@v3.sk: Turn the addresses to strings from guint8[ETH_ALEN], as that
is what rest of NetworkManager uses for MAC addresses and what Bluez utility
functions expect as well.]
Previously, nm_setting_diff() (and thus nm_connection_diff()), returned
only properties that are different AND not set to the default value.
However, if the opposite setting 'B' was missing, it would always
include all properties from 'A', even the default ones.
This behaviour was asymetric. Add two new compare flags
@NM_SETTING_COMPARE_FLAG_DIFF_RESULT_WITH_DEFAULT and
@NM_SETTING_COMPARE_FLAG_DIFF_RESULT_NO_DEFAULT to control the
behaviour of whether to include default properties.

When secret providers return the connection hash in GetSecrets(),
this hash should only contain secrets. However, some providers also
return non-secret properties.
for_each_secret() iterated over all entries of the @secrets hash
and triggered the assertion in nm_setting_get_secret_flags() (see
below).
NM should not assert against user provided input. Change
nm_setting_get_secret_flags() to silently return FALSE, if the property
is not a secret.
Indeed, handling of secrets is very different for NMSettingVpn and
others. Hence nm_setting_get_secret_flags() has only an inconsistent
behavior and we have to fix all call sites to do the right thing
(depending on whether we have a VPN setting or not).
Now for_each_secret() checks whether the property is a secret
without hitting the assertion. Adjust all other calls of
nm_setting_get_secret_flags(), to anticipate non-secret flags and
assert/warn where appropriate.
Also, agent_secrets_done_cb() clears now all non-secrets properties
from the hash, using the new argument @remove_non_secrets when calling
for_each_secret().

Add configuration option NMSettingConnection:autoconnect-priority.
This new option is only relevant for connections that are set to
autoconnect. When having more then one candicate for autoconnect, this
new setting allows to always prefer one connection over the other.
If both connections have the same priority setting, the previous
automatism is used to choose the best candidate. That is, NM will
choose the least recently connected candidate.
See also the still unresolved but related bug bgo#737356 that asks
for providing a different automatism.

nm_device_get_best_auto_connection() was only used at one place.
It was a very simple function, just iterated over a list finding
the first can_auto_connect() connection. At the very least, the name
was misleading, because it did not return the 'best', but the 'first'
connection.
Get rid of the function altogether.

The autoconnect priority has only any relevance, if the connection
is autoconnect too.
The priority defaults to zero, with higher numbers meaning preferred.
The valid range is limited to [-999,999].

If the assertion in verifies_without_normalization() fails due to
@was_modified, the error message is not helpful.
Assert first against the content of the connection. This prints
most likely the settings that were actually modified.

nm_client_new_async() got broken in the NMManager split. Fix it, and
use it from one of the tests in test-nm-client to make sure it's
getting tested in the future.
NMActiveConnection:connection was an object path rather than an
NMRemoteConnection because in the past the NMObject property system
wasn't capable of handling NMRemoteConnection-valued properties.
NMActiveConnection:master was an object path rather than an NMDevice
entirely by accident. Fix both.
NMActiveConnection:specific-object can't currently be converted to an
object, because we don't know ahead of time what object type it is,
and NMObject can't deal with that. Instead, we rename it to
:specific-object-path (and likewise for its get function), both to
emphasize that it doesn't behave like other properties, and to leave
the old name open for an actual object-valued property later on.
Add a single function to check if NM is running and set a GError if
not, then use it as appropriate.
Don't bother to check if NM is running in get_*() functions if
nm_running_changed_cb() would have reset the field anyway (and fix
that up to reset a few more fields).
Rearrange the NMClient function declarations and the functions
themselves, and group them into "general", "device", and "active
connection" sections.
No code changes, just moving things around.
All callers only pass a PID that previously was returned from
spawning a process. AFAIS, there is no officially reserved range
for lower PIDs that would enforce valid PIDs to be larger then 25.
Relax this check.
