The recent put*ent hardening changes broke the build for i386. i386
defines internal_function to __attribute__ ((regparm (3), stdcall)),
which affects type compatibility, so requiring internal_function to be
used consistently on declarations and definitions. This patch adds
internal_function to the definitions of the new functions using it on
their declarations.
Tested for i386 that this fixes the build.
* nss/rewrite_field.c (__nss_rewrite_field): Use
internal_function.
* nss/valid_field.c (__nss_valid_field): Likewise.
* nss/valid_list_field.c (__nss_valid_list_field): Likewise.

This prevents injection of ':' and '\n' into output functions which
use the NSS files database syntax. Critical fields (user/group names
and file system paths) are checked strictly. For backwards
compatibility, the GECOS field is rewritten instead.
The getent program is adjusted to use the put*ent functions in libc,
instead of local copies. This changes the behavior of getent if user
names start with '-' or '+'.
