To mitigate this, introduce a libcasper service that is responsible for fetching and returning new, requested resources to syslogd. Some resources must be packed into an nvlist to be properly transferred between syslogd and the libcasper process. The filed_to_nvlist() and nvlist_to_filed() functions are included to ease the packing process for filed structures. Two additional syslogd.h and syslogd_cap.h header files are included with shared declarations.
