svn: initial "master" points to trunk if possible

Since "trunk" is a convention for the main development branch in
the SVN world, try to make that the master branch upon initial
checkout if it exists.  This is probably less surprising based
on user requests.

t9135 was the only test which relied on the previous behavior
and thus needed to be modified.
