Re: #1463 (Third party media support). Tnitial work and it works, tested on Linux. Details:

• add PJSUA_MEDIA_HAS_PJMEDIA macro
• move pjmedia specific implementation in pjsua_media.c and pjsua_call.c into pjsua_aud.c
• add pjsip-apps/src/third_party_media sample containing:
  • alt_pjsua_aud.c
  • alt_pjsua_vid.c
• moved pjmedia_vid_stream_info_from_sdp() into pjmedia/vid_stream_info.c
• moved pjmedia_stream_info_from_sdp() into pjmedia/stream_info.c
• misc: fixed mips_test.c if codecs are disabled
