[connman] log: allow disabling certain logs

Log patterns prefixed with ! disable the logging. That makes it
possible to enable logs everywhere except for the specific files
which don't interest the person doing the debugging.

[connman] service: plugged memory leak

The value returned by connman_storage_get_services() needs to be deallocated

[connman] allow user input request signal when using autoconnect.

If passphrase gets changed, it needs to pass on the user Input request
signal to clients to be able to re-autoconnect.
[connman] try connecting to failure state service.

Tries at least once regardless, if there still is invalid-key error,
send User Input Requested via agent. If user cancels that request,
stop trying to connect.

This helps when a wireless AP with same ssid/enc but unknown
comes within range. connman issues an invalid-key, as the passwords
are different. Which would cause connman to not try and connect when the
good, known AP comes within range.
[connman] fix crash and report error properly.

[connman] Increase maximum size of stats files.

The default maximum size of the stats files was 16 kB. However, now
that each record is approximately twice as big (due to the change from
32 bit to 64 bit data types) the number of records which can be stored
has halved. To compensate increase the default maximum size to 32 kB.
