Add new video codec priority policy, that gives preference to hardware codecs on mobile platforms, in order to preserve battery and improve framerate.

Free mConferenceFactoryAddressCstr in AccountParameters destructor

Make ChatMessagePrivate::setState private because the chat message state
can only be set by ChatMessagePrivate::setParticipantState if has to be
changed from outside of the ChatMessage object

A message can only reach an IMDN controlled state when the core receives
an IMDN. This avoid moving a message to NotDelivered when resending it
as all participants are in NotDelivered state

 Caught exception in MainDb::updateEvent(sqlite3_statement_backend::prepare: no such column: event_id while preparing "SELECT sip_address.value FROM sip_address WHERE event_id = :eventId AND sip_address.id = chat_message_participant.participant_sip_address_id" with :1=5.).

Remove useless jazzy stuff + Rename ENABLE_JAZZY_DOC option to ENABLE_SWIFT_DOC + Fix line returns in swift doc template.

Enable tests that only enable STUN and/or ICE in account parameters

- SQLite doesn't allow to modify contraints of tables therefore a
workaround to do so is to recreate the table from scratch.
The old table is therefore cloned and the values are copied tot he newly
created table.
The cloning is done through the CREATE statement specifying the type of
every column in order to keep it unchanged. If we were to clone and
populate the table in one line using query "CREATE TABLE IF NOT EXISTS
clone AS SELECT * FROM original", we might incur in a data type change.
For example DATE columns are converted to NUM column in the clone table.
The cloned table is populated using the INSERT statememnt and then the
old table can be deleted.
A new table with the desired contraints is then created and populated
one line at a time or in one query.

[MainDb]
- Catch soci exception in the init or updateSchema function and
pass them on to the calling function to be handled.
- Make MainDb::isInitialized() return FALSE if the database
  initialization failed
- In AbstractDb::connect(), catch soci exception and reset DB session if
  they are of type invalid_staement or constraint_violation as an attempt to reconnect to the database won't fix the issue.
- After initializing the database, clean up clone tables in a separate
  SQL statemment to avoid the following error
  'sqlite3_statement_backend::loadOne: disk I/O error while executing "<statement>"'

[MainDbTester]
- Verify that the database has been correctly initialized
- Do not attempt to retrieve data if the database has not been correctly
  initialized

   Set it as Address in account parameters and core in order to easily
   take advantage of address comparison, parameter management and
   compliance with RFC3261

Conference:
  Allow applications to directly mute licrophone and get input device
  volume through the conference object.
  This will ensure that whatever type of confenrece is and regardless if the
  device is hosting or being a participant, the application will have only
  one interface to use and the SDK will work under the hood.

Deprecated methods:
  Delete linphone_core_mute_mic and linphone_core_is_mic_muted
  Add LINPHONE_DEPRECATED to deprecated Account parameter methods

Tester:
  Pass conference factory uri to ClientConference constructor instead of
  focus identity

Memory leaks:
  Free data of list returned by linphone_friend_get_phone_numbers

the remote contact address if not null when the call state is
StreamRunning or Paused and the conference is in state Created or
CreationPending

Add "LeaksMemory" to "Core restarts as soon as chat room is created"

Adapt video call quality tests to take into account changes in network simulator and available bandwidth estimator.
Fix initialization of NatPolicy that could be left orphaned in case of remote provisionning with default_values.

Removed code delaying rotation update in Core (no longer needed) + improved use of handlers to use the same one the Core was created on and thus prevent deadlocks

Fix bug where the push_parameters string read from the configuration files for accounts was deleted and replaced by the core's push notification config all the time, instead of only by default

Allow NULL particiant device joining time. This is required because the
joining time is the time the device state switches to Present, therefore
it is NULL when the device is added to the chatroom or conference

- Add table conference_info_participant_params to store participant parameters instead of putting them as a string in conference_info_participant
  Change participant role from Unknown to Speaker during the migration
- Do not use table conference_info_organizer anymore and move its content to table conference_info_participant
- Delete MainDbPrivate::selectConferenceCallEvent as unused

ChatMessagePrivate::setParticipantState and
ChatMessagePrivate::setState.

All event regarding a chat message will now chat the state of a
participant and then if neecesary the state of the chat message will
follow.

For IMDN controlled stats (i.e. DeliveredToUser, NotDelivered and
Displayed), the state of the chat message will be deduced based on the
states of all participants

For non-IMDN controlled states, the state of the chat message will
follow the state of the me of the chat room the message it associated
with
