[RFC] warn people about the permanence of branches

[timeless]

What if we had a file ".hgbranchnaming" whose tip rules controlled
warning free branch names.

It could support regexp/glob/static.

No file = warn for all

A file with just "stable" would warn for any other names.

A file with "glob:rel-*" would allow any rel- branches but nothing
else (without warnings).

The file could be generic to apply to both tags and branches with
sections, or there could be two.
