[meta]: Add long-term reference index to meta data

Browse source 
This meta data is used for SVC/TSVC encoding / decoding.

Cases and meaning when using KEY_LONG_REF_IDX:

1. On decoder output frame
Represents the long-term reference frame index of the output frame.

2. On encoder input frame
Represents the long-term reference frame which should be used as
reference frame for current encoding frame.

3. On encoder output packet
Represetns the long-term reference frame index of the output packet.
