Subject: [PATCH 1/2] audit: move extern declarations to audit.h

Leave audit_sig_{uid|pid|sid} protected by #ifdef CONFIG_AUDITSYSCALL.

Noticed by sparse:
kernel/audit.c:73:6: warning: symbol 'audit_ever_enabled' was not declared. Should it be static?
kernel/audit.c:100:8: warning: symbol 'audit_sig_uid' was not declared. Should it be static?
kernel/audit.c:101:8: warning: symbol 'audit_sig_pid' was not declared. Should it be static?
kernel/audit.c:102:6: warning: symbol 'audit_sig_sid' was not declared. Should it be static?
kernel/audit.c:117:23: warning: symbol 'audit_ih' was not declared. Should it be static?
kernel/auditfilter.c:78:18: warning: symbol 'audit_filter_list' was not declared. Should it be static?
