Changes since 1.8: +4 -2 lines

Add bunch of missing includes of namespace.h in libc

The NetBSD Standard C Library uses internally some of its functions with
a mangled symbol name, usually "_symbol". The internal functions shall not
use the global (public) symbols.

This change eliminates usage of the global changes of the following symbols:
 - strlcat -> _strlcat
 - sysconf -> __sysconf
 - closedir -> _closedir
 - fparseln -> _fparseln
 - kill -> _kill
 - mkstemp -> _mkstemp
 - reallocarr -> _reallocarr
 - strcasecmp -> _strcasecmp
 - strncasecmp -> _strncasecmp
 - strptime -> _strptime
 - strtok_r -> _strtok_r
 - sysctl -> _sysctl
 - dlopen -> __dlopen
 - dlclose -> __dlclose
 - dlsym -> __dlsym
