[connman] change all connman_info to DBG

connman_info does not have file names in it's output, so it would not
be included in the block out by doing -d '*:!src/rtnl.c'

This effectively makes the output more manageable and readable when
debugging.
This included stat and newlink info clogging the output.
[connman] ofono: set_property_calls table was destroyed too early

It should be kept alive until after we made all the calls that can call us back.
Otherwise we may end up accessing hashtable that has already been destroyed.
[connman] fix crash and report error properly

connect_service() calls __connman_service_connect() which may in turn call
reply_pending() which unrefs service->pending and sets it to NULL. Therefore,
connect_service() needs to check service->pending for NULL prior to calling
dbus_message_unref() on it.

Also, __connman_error_failed() expects a positive error code.

[connman] service: cancel agent requests prior to deleting wispr context

Calling __connman_wispr_stop() without connman_agent_cancel() allows pending
wispr requests to complete later which results in a read/write access to the
freed memory and a subsequent crash.

Calling connman_agent_cancel() without __connman_wispr_stop() stops the wispr
sequence which renders the wispr context useless. That makes no sense either.

[connman] Don't override user setting when setting auto proxy url via dh...
[connman] Enhance online check.

This enhances the online check by continusously checking for
connectivity if it fails. Previously it would check up to 12 times
and then give up. Don't give up, instead continue checking at the
maximum interval until it succeeds.

If the user changes the proxy configuration redo the online check.

Fixes issues with calling __connman_wispr_start() multiple times. If
there is a pre-existing wispr context it is cancelled, freed, and
recreated. However, no all network operations are cancelled or able to
be cancelled. Causes freed memory to be accessed when the network
operation completes.
