This script automates some updates that should be made when branching
from trunk. Putting them in a script makes it much easier and means I
won't forget what should be done.

Any suggestions for doing this differently?

Anything I've forgotten that should be added here?

We could add an entry to the lists of versions at
https://gcc.gnu.org/onlinedocs/libstdc++/manual/abi.html#abi.versioning.goals
but that should really be done when bumping the libtool version, not
when branching from trunk.

This should be run on a release branch after branching from trunk.
Various links and references to trunk in the docs will be updated to
refer to the new release branch.
