dlfcn: Guard __dlerror_main_freeres with __libc_once_get (once) [BZ# 24476]
dlerror.c (__dlerror_main_freeres) will try to free resources which only
have been initialized when init () has been called. That function is
called when resources are needed using __libc_once (once, init) where
once is a __libc_once_define (static, once) in the dlerror.c file.
Trying to free those resources if init () hasn't been called will
produce errors under valgrind memcheck. So guard the freeing of those
resources using __libc_once_get (once) and make sure we have a valid
key. Also add a similar guard to __dlerror ().
* dlfcn/dlerror.c (__dlerror_main_freeres): Guard using
__libc_once_get (once) and static_bug == NULL.
(__dlerror): Check we have a valid key, set result to static_buf
otherwise.

When computing the length of the converted part of the stdio buffer, use
the number of consumed wide characters, not the (negative) distance to the
end of the wide buffer.
nss: Turn __nss_database_lookup into a compatibility symbol
The function uses the internal service_user type, so it is not
really usable from the outside of glibc. Rename the function
to __nss_database_lookup2 for internal use, and change
__nss_database_lookup to always indicate failure to the caller.
__nss_next already was a compatibility symbol. The new
implementation always fails and no longer calls __nss_next2.
unscd, the alternative nscd implementation, does not use
__nss_database_lookup, so it is not affected by this change.

iconv: Remove public declaration of __gconv_transliterate
Commit ba7b4d294b01870ce3497971e9d07ee261cdc540 ("Complete the
removal of __gconv_translit_find") added a declaration of the
GLIBC_PRIVATE function, __gconv_transliterate, to the installed
header <gconv.h>. It should have been added to the internal
<gconv_int.h> header.
