SPF API Linkage and Visibility #10

Open wahern opened 8 years ago

Copy linkage and visibility improvements from dns.c to spf.c. Specifically, qualify API functions with SPF_PUBLIC in spf.h, and move extern objects behind a function interface so visibility can be easily controlled using the simple SPF_PUBLIC macro.
