Log Message:
Updated sofia-sip to upstream version 1.12.11. According to the release notes:
- Added functions auth_digest_ha1(), auc_save_credentials(), and
  auc_copy_credentials()
- Added function msg_fragment_clear_chain().
- Added tag SOATAG_DELAYED_OFFER_ENABLE().
- Added tags NUTAG_AUTO302(), NUTAG_AUTO305().
- Added functions nta_outgoing_magic(), nta_agent_tports(),
  nta_leg_client_reroute().
- Added functions su_home_parent(), su_root_clone(),
  su_root_set_max_defer(), su_root_get_max_defer(),
  su_timer_deferrable(), su_timer_is_set(), su_timer_latest(),
  su_task_deferrable(), su_task_wakeup().
- Added locale-independent, NULL-safe string comparison, matching and
  searching functions:
    su_strcmp(), su_strncmp(), su_strcasecmp(), su_strncasecmp(),
    su_strmatch(), su_strnmatch(), su_casematch(), su_casenmatch(),
    su_strncspn(), su_strnspn(), su_strcasestr(), su_memspn() and
    su_memcspn().
- The mp_len type was changed from usize_t to unsigned.
  The change is binary-incompatible on 64-bit platforms when compiled with
  the configure option --disable-size-compat
- Removed globals which should have been static in first place:
  - su_t64_to_time()
  - mutex_trylocker()
  - su_port_set_system_preferences()
  - t_null_next(), t_null_move(), t_null_dup(), t_null_copy(), t_null_find()
  - t_skip_next(), t_skip_move(), t_skip_len(), t_skip_dup(), t_skip_filter()
  - t_next_next(), t_next_move(), t_next_len(), t_next_dup(), t_next_filter()
  - t_filter_with(), t_any_filter()
  - sres_record_class(), urandom
  - u2s_alloc()
  - memmem (on platforms that do not support memmem)
- This release is ABI/API compatible with applications linked against
  any 1.12.x release. However, applications built against this release won't
  work against an older library. The ABI has been tested with the nua module
  unit test (test_nua) built against original 1.12.0 release.

libsofia-sip-ua-glib:
- No ABI/API changes, compatible with 1.12.0. Note, libsofia-sip-ua-glib
  interface is not considered stable and may change in a future 1.12.x
  release.
