Protocol and build system change ...

* Use autoheader
* Add --enable-minmem
* Add OS code. Bin archive and protocol changed accordingly
* Add instance flags in hostinfo frame. Bitfield util added for this
* Add org_id in hostinfo for lineage record
* SQL schema change: store integer value of hostinfo arch and os
* Remove config.c
* prne_index_nybin() now sets errno
* Instance ids are now preserved for lineage record
* Proone: remove arguments after init
* Fix bug in prne_htbt_ser_bin_meta(): alloc_len is not checked
