Subject: Fix a parsing problem with little data at startup

* parser.c: inkscape extension loader (and possibly others) feed
  data to the parser very slowly, 0 at start, 4 bytes on first GROW
  and this broke after the fix for
  https://bugzilla.gnome.org/show_bug.cgi?id=566012
  http://git.gnome.org/cgit/libxml2/commit/?id=7e385bd4e28a0cc12b6b26ed178c620e3c3ab8d8
  leading to another bug
  https://bugzilla.redhat.com/show_bug.cgi?id=523002
  this detects the situation and GROW when needed for proper processing.
