Initial commit re #1263 (PJSUA-LIB Video API):
 - API designed and reviewed (pjsua.h)
 - Implemented these APIs and added to pjsua sample application:
   - video device enums API
   - video capture preview API
 - refactoring in PJSUA-LIB:
   - video stuffs go to pjsua_vid.c
   - call dump goes to pjsua_dump.c

We're still missing:
 - video call API implementation
 - media info and statistic API implementation
