commit: remove special handling of IOError (actually dead code)

In the past, IOError was used to mark a file as removed. The differentiation
between OSError and IOError in this place was introduced in e553a425751d, to
avoid that “normal” OSErrors / IOErrors accidentally mark files as removed.
This weird internal API was removed in 650b5b6e75ed. It seems like that
changeset should have removed the differentiation, at least I don’t see any
reason for keeping it.

On Python 3, OSError and IOError are aliased. Therefore the removed code was
actually dead.

Now test that it works with trunk/tags layout, but no branches yet.

Initial svn import

  Checked out revision 1.
  $ cd B
  $ echo hello > 'letter .txt'

Convert to hg once and also test localtimezone option

NOTE: This doesn't check all time zones -- it merely determines that
the configuration option is taking effect.

An arbitrary (U.S.) time zone is used here.  TZ=US/Hawaii is selected
since it does not use DST (unlike other U.S. time zones) and is always
a fixed difference from UTC.

Test converting empty heads (issue3347).
Also tests getting logs directly without debugsvnlog.

Test that a too-new repository format is properly rejected:
  $ mv svn-empty/format format
  $ echo 999 > svn-empty/format
It's important that this command explicitly specify svn, otherwise it
can have surprising side effects (like falling back to a perforce
depot that can be seen from the test environment and slurping from that.)
