[Clas_offline] C function to force flushing of BOS buffer?

[boiarino at jlab.org]

Hello all,
BOS originally had several bank lists, assuming that 'E' will be used
to store raw data banks, 'C' for calibration banks and so on. I think
we assume that 'E' list is for data, others are not specified, although
can be used, and maybe used somewhere in our software.
'0' is a special case, forcing last buffer to be written, as it was pointed
by Gagik.
