While looking at PR100731, I have noticed the copyright years are 2020-ish
only. This patch adds it to update-copyright.py and updates those.

With the introduction of C++20 modules and libcody, cc1plus and
cc1objplus gained a dependency on the socket functions. Before those
were merged into libc in Solaris 11.4, one needed to link with -lsocket -lnsl
on Solaris, so that merge broke the Solaris 11.3 build.
While we already have 4 different checks for those libraries in the
tree, I decided to import autoconf-archive's AX_LIB_SOCKET_NSL macro
instead. At the same time, the patch only links libcody and the
networking libs where needed (cc1plus, cc1objplus).
Bootstrapped without regressions on i386-pc-solaris2.11 (Solaris 11.3
and 11.4), sparc-sun-solaris2.11, and x86_64-pc-linux-gnu.

This adds --enable-default-pie support to c++tools, so that the sample
server is build -fPIE if requested.

When breaking out the sample server from the gcc/cp directory, it lost
its check for mmap, and the sample resolver just assumed it was there.
Fixed thusly. The non-mapping paths in module.cc weren't (recently)
excercised, and led to a signedness warning. Finally I'd missed
c++tools's config.h.in in the gcc_update script. There I took the
opportunity of adding a 'tools' segment of the dependency lists.

Seems c++tools doesn't honor --with-gcc-major-version-only.
Our distro uses that flag and so everything is installed in
/usr/lib/gcc/<target>/11/...
/usr/libexec/gcc/<target>/11/...
except
/usr/libexec/gcc/<target>/11.0.0/g++-mapper-server
The following patch should fix that.

Part of our module implementation adds a sample mapper server, the
guts of which are used by the default in-process mapping of cc1plus.
Rather than add another executable to gcc/cp/, this creates a new
c++tools directory where this and any other c++ tools might live.
The toplevel changes are a subsequent commit, because ... git.
