LU-1214 ldlm: splits server specific lock handling from client

Splits/removes these server-side specific lock handlings:
1. Server-side blocking/completion/glimpse AST
2. ldlm_cancel_service
3. Resource policy functions
4. ldlm_handle_enqueue /ldlm_handle_convert etc.

Uses "HAVE_SERVER_SUPPORT" to comment out those server-side codes.
