Feature/create object initial value backup (#1223)

* Added example Device object and property value backup using create-object list-of-initial-values and writable properties. Initiated using ReinitializeDevice with STARTBACKUP command. Added backup and restore required properties to the Device object.

* Fixed fwrite parameters in bacfile_posix_write_stream_data to return the correct number of bytes written.

* Added Device Management-Backup and Restore-B (DM-BR-B) conversion to Wireshark PCAP format command line utility in apps/dmbrcap which decodes and provides a view of the binary backup file.
