lxml-based doctest output comparison.

Note: normally, you should just import the `lxml.usedoctest` and
`lxml.html.usedoctest` modules from within a doctest, instead of this
one::

    >>> import lxml.usedoctest # for XML output

    >>> import lxml.html.usedoctest # for HTML output

To use this module directly, you must call ``lxmldoctest.install()``,
which will cause doctest to use this in all subsequent calls.

This changes the way output is checked and comparisons are made for
XML or HTML-like content.

XML or HTML content is noticed because the example starts with ``<``
(it's HTML if it starts with ``<html``).  You can also use the
``PARSE_HTML`` and ``PARSE_XML`` flags to force parsing.

Some rough wildcard-like things are allowed.  Whitespace is generally
ignored (except in attributes).  In text (attributes and text in the
body) you can use ``...`` as a wildcard.  In an example it also
matches any trailing tags in the element, though it does not match
leading tags.  You may create a tag ``<any>`` or include an ``any``
attribute in the tag.  An ``any`` tag matches any tag, while the
attribute matches any and all attributes.

When a match fails, the reformatted example and gotten text is
displayed (indented), and a rough diff-like output is given.  Anything
marked with ``+`` is in the output but wasn't supposed to be, and
similarly ``-`` means its in the example but wasn't in the output.

You can disable parsing on one line with ``# doctest:+NOPARSE_MARKUP``
