[v3] libstdc++/49829

- Subject: [v3] libstdc++/49829
This modularizes the libstdc++ sources such that the resulting library
binaries are now composed of three convenience libraries. In short:
libstdc++.[a, so] == libc++98 + libc++11 + libsupc++
Arguably, this is the way it should have been done all along. And
certainly since the C++11 support hit 5 or more files....
In any case, this helps resolve the knots gcc/libstdc++ config and
build get themselves into when gcc requires static libstdc++, but the
build says no-static (--disable-static).
There are some warts that need addressing by a proper build maintainer.
1) dependency tracking for libstdc++convenience.la. Help. It's not
installed and not really used in most cases, so this isn't crucial.
But, perfection is a cruel mistress, and I'd like to get this right.
2) I suppose the docs should be updated to reflect this. To-do.
I'm trying to get over my fear of using git for check-ins that require
a bunch of renames etc etc. So, this is my first one of these. If I did
it all wrong, please let me know gently and I'll try to fix it.
This patch is huge due to all the re-names. Please check out the patch
posted in bugzilla instead.
best,
benjamin
