Update routines to write out SOS DC  info to ntuple

1) Move call h_dc_ntuple_keep to g_keep_results so that it is called for all event types
2) Update h_dc_ntuple_keep
    a) put SOS DC variables into ntuple
    b) have HMS variables start with hdc
    c) hardwire to only write out SOS events (evtype =2)
3) Update h_dc_ntuple_open
    a)  have HMS variables start with hdc
    b)  add SOS DC variables under SDCINFO common block
    c) add iquest(10)=65000 to allow larger ntuple file size
4) In h_keep_results : remove call h_dc_ntuple_keep
5) In gen_pawspace.cmn increase size of G_sizeHBOOK to 8000000
6) Update h_dc_ntuple.cmn
    a)  have HMS variables start with hdc
    b)  add SOS DC variables under SDCINFO common block
