push: add --publish flag to change phase of pushed changesets

This flag is copied from topic extension, where it proved to be useful. It
makes all pushed changesets public on both ends if the push succeeds.

Doesn't currently work for any subrepos that are implicitly pushed together
with their owner repo.

# Read the output of a "svn log --xml" command on stdin, parse it and
# print a subset of attributes common to all svn versions tested by
# hg.
