-linphone_call_error_info_to_sal_op into linphone_error_info_to_sal as there is no LinponeCall object  involved here.
- linphone_call_terminate_with_error into linphone_call_terminate_with_error_info
Fixes in linphone_call_terminate_with_error_info.

Adding checks in sal_call_terminate_with_error

Adding new API int linphone_call_terminate_with_error_info(LinphoneCall *call, const LinphoneErrorInfo *ei) and other functions to handle  RFC3326 reason header.

Make LinphoneErrorInfo a belle-sip object. Add new accessors, and make it able to take Reason headers in incoming requests (feature to be tested)

Added linphone_call_get_params to get local call params used.
Added tests .

fix parsing of report blocks in linphone_call_stats_get_sender_loss_rate() and linphone_call_stats_get_receiver_loss_rate()

Perform an ICE reset instead of an ICE restart when recovering from a connection loss (it has the effect to also clear the previous local candidates).

- can use expression like 1W, 2M or 3d instead of number of seconds

make sure that rtp statistics reported from LinphoneCall are updated after a stream terminates, so that it really says the exact number of packets that were received and sent.
