[PATCH 1/2] Add the DTV_ISDB_TS_ID property for ISDB_S

[PATCH 1/2] Add the DTV_ISDB_TS_ID property for ISDB_S

[hiranotaka]

Add the DTV_ISDB_TS_ID property for ISDB-S

In ISDB-S, time-devision duplex is used to multiplexing several waves
in the same frequency. Each wave is identified by its own transport
stream ID, or TS ID. We need to provide some way to specify this ID
from user applications to handle ISDB-S frontends.

This code has been tested with the Earthsoft PT1 driver.

Committed, thanks. I had to fix a merge conflict with the ISDB-T API additions.

I also added an "s" after ISDB to use the same name convention used on other
API functions.



Cheers,
