git-svn: avoid fetching files twice in the same revision

SVN is not entirely consistent in returning log information and
sometimes returns file information when adding subdirectories,
and sometimes it does not (only returning information about the
directory that was added).  This caused git-svn to occasionally
add a file to the list of files to be fetched twice.  Now we
change the data structure to be hash to avoid repeated fetches.

As of now (in master), this only affects repositories fetched
without deltas enabled (file://, and when manually overriden
with GIT_SVN_DELTA_FETCH=0); so this bug mainly affects users of
1.4.4.1 and maint.

Thanks to Florian Weimer for reporting this bug.
