/***************************************************************************
* msr_pack:
*
* Pack data into SEED data records. Using the record header values
* in the MSRecord as a template the common header fields are packed
* into the record header, blockettes in the blockettes chain are
* packed and data samples are packed in the encoding format indicated
* by the MSRecord->encoding field. A Blockette 1000 will be added if
* one is not present.
*
* The MSRecord->datasamples array and MSRecord->numsamples value will
* not be changed by this routine. It is the responsibility of the
* calling routine to adjust the data buffer if desired.
*
* As each record is filled and finished they are passed to
* record_handler which expects 1) a char * to the record, 2) the
* length of the record and 3) a pointer supplied by the original
* caller containing optional private data (handlerdata). It is the
* responsibility of record_handler to process the record, the memory
* will be re-used or freed when record_handler returns.
*
* If the flush flag != 0 all of the data will be packed into data
* records even though the last one will probably not be filled.
*
* Default values are: data record & quality indicator = 'D', record
* length = 4096, encoding = 11 (Steim2) and byteorder = 1 (MSBF).
* The defaults are triggered when the the msr->dataquality is 0 or
* msr->reclen, msr->encoding and msr->byteorder are -1 respectively.
*
* Returns the number of records created on success and -1 on error.
