topic: allow unicode symbols in names as long as they are alphanumeric

I decided to relax this logic just a little bit to allow unicode "word
characters" (i.e. everything that a unicode regex \w matches). This is still
limiting cases that core allows (for branches and bookmarks): core only forbids
certain byte values (like null byte, see scmutil.checknewlabel function).

This extra check for topic names could be dropped altogether and we could rely
solely on checknewlabel(), but I don't know if there isn't some corner case
that topics can't handle. Needs more investigation (and tests).

This test amends a merge commit using various commands, including topics

  $ . $TESTDIR/testlib/common.sh

  $ cat >> $HGRCPATH << EOF
  > [extensions]
  > evolve =
