[PATCH 0/8] Move nss_files into libc

[Florian Weimer]

I plan to use this to tackle the --enable-static-nss regression in glibc
2.33.

I plan to move nss_dns into libc as well, and then we can add a library
with dlopen stubs that blocks all dlopen calls.  If a programmer wants
to build a truly static binary, they can link with -lglibc-nodlopen (or
something like that), and the behavior will be as if glibc was
configured with --enable-static-nss.

Tested on i686-linux-gnu and x86_64-linux-gnu.  Built using
build-many-glibcs.py.

Thanks,
Florian
