Register HandsfreeAudioManager straight away at startup

See merge request !277

To ensure that all D-Bus objects which should be available straight
after startup are there when the first incoming D-Bus call arrives.

Those functions are called by ofono_handsfree_audio_ref/unref which
ensure that initialization is only done once.

Otherwise it's not clear how the client is supposed to wait for
org.ofono.HandsfreeAudioManager to appear and how to figure out
whether it's ever going to appear.

Don't try to connect HFP AG if bluetooth service is not available.

See merge request !276

Trying to connect too soon will result in profile interface registration
failure with timeout error, effectively blocking for dbus timeout (25s
by default).

[ril] Calculate signal strength based on rsrp value correctly. JB#50995.

See merge request !275

All the dBm values are converted to qdbm (multiply by 4) but rsrp which
results in incorrect signal strength representation on some devices.

[ril] Add config options for cell info update interval. JB#50608

See merge request !273

According to ril.h, a value of 0 means invoke RIL_UNSOL_CELL_INFO_LIST when
any of the reported information changes.

It's not obvious where it actualy comes from, let's have it in the build log.

[ofono] Don't support '.' as a DTMF pause character. Contributes to JB#50214

[aarch64] Use macros for unitdir. Contributes to JB#49681

Tweak CBS request retry logic

See merge request !270

I swear I've seen such cases!

There's no need for RIL_REQUEST_GSM_GET_BROADCAST_SMS_CONFIG, since we
are not using its result anyway. Better just register for notifications
which would simply never arrive if CBS doesn't work at all.

Important requests, however, better be retried on RIL_E_INVALID_STATE.

Allow the last CBS fragment to be truncated.

See merge request mer-core/ofono!269

That does happen in real life.

Refactring radio caps code

See merge request !261

The radio caps manager will not do anything until the roles are assigned
to modems, so data manager must select the modem with highest capabilities
for LTE instead of the first one.

At startup, the device may have an inconsistency between data and voice
network modes, so it needs to be asserted.

Workaround for bogus operator names in network scan

See merge request !152

Fix parsing of NEW_BROADCAST_SMS packet

See merge request !268

It's 4-byte length followed by the specified number of bytes
zero-padded to 4-byte boundary. Kind of like a string.

Some RILs (e.g. Sony Xperia X, MediaTek) report bogus operator names
in response to QUERY_AVAILABLE_NETWORKS request. We can make user's
life easier by looking up possible operator name in MBPI database
based on MCC and MNC (assuming those are reported correctly) in case
if weirdness is detected.

To turn this feature on, add this to /etc/ofono/ril_subscription.conf
config file:

replaceStrangeOperatorNames=true

Provide SmsHistory interface for all modems.

See merge request !266

The SmsHistory plugin uses a global variable to determine if it is already
registered. Because of that, Ofono provides org.ofono.SmsHistory only for
the first modem, and SMS delivery notifications do not work on the others.
After this commit is applied, the plugin will be registered for each modem.

Even though it's RIL specific, it makes sense to reuse the
existing access control mechanism.
