* nss/Makefile (databases): New variable.
(routines, libnss_files-routines): Use it.
(subdir-dirs): Compute from $(services).
* sysdeps/unix/sysv/linux/syscalls.list (create_module, delete_module,
init_module, klogctl): Use EXTRA in the "caller" column so these get
added to unix-extra-syscalls and thus compiled in misc.

* string/strndup.c: New file.
* string/string.h: Declare strndup.
(strndupa): New macro.
* string/string.h: Declare __strdup.

KEEP_STREAM every time called.
(_nss_files_end): Reset KEEP_STREAM here instead.
(internal_getent): If STREAM == NULL try to open instead of
signalling error.
Use cast to prevent warning.
Terminate read line in case the buffer is too small.
