We should make sure these are all intended to be public

auth_getval() is a compatibility stub, we can drop it now (it will be provided by the misc/compat14x port's copy of libutil.so.9)
checkpath_allow_file() is undocumented but used by mount(8)
domainset_parselist() does have a man page in main (but not in 14)
getmnt_silent is documented in mntopts(3), we don't usually have MLINKs for variables (with notable exceptions such as errno(2) and environ(7))
gr_*() are undocumented but used by pw(8)
kinfo_getswapvmobject() is undocumented but used by systat(8)
login_getcapenum() is documented but missing an MLINK
login_hostok(), login_strinlist(), login_str2inlist(), login_timelist(), login_ttyok() are undocumented and only used internally, but going by code comments, clearly intended to be public
pidfile_signal() is undocumented but clearly intended to be public, and used by mount(8)
pw_initpwd() is documented but missing an MLINK
quota_check_path(), quota_convert(), quota_maxid(), quota_off(), quota_on() are documented but missing MLINKs
setclasscpumask() is documented but missing an MLINK
