In addition to adding missing `static' keywords: - bin/dd: Pull in `extern.h' to guarantee consistency with source file. - libexec/rpc.rusersd: Move shared globals into an extern.h. - libexec/talkd: Move `debug' and `hostname' into extern.h. - usr.bin/cksum: Put counters in extern.h, as they are used by ckdist/mtree. - usr.bin/m4: Move `end_result' into extern.h. - usr.sbin/services_mkdb: Move shared globals into an extern.h.
