Jonathan Clark 43cd683230 tdf#36709 Add loext:text-indent supporting font-relative units 
This change adds an ODF font-relative first-line indent paragraph style
attribute as a LibreOffice extension. The corresponding ODF standard
change is tracked by OFFICE-4165.

This change only implements what is minimally necessary to serialize,
deserialize, and check for ODF files containing this attribute. Further
changes are necessary.

* Added cssLength to schema, which is equivalent to length but also
  allows ic and em as units.
* Added loext:text-indent to schema as a paragraph style attribute. This
  attribute is equivalent to fo:text-indent, but accepts cssLength
  instead of length.
* Added XML_TYPE_UNIT_MEASURE to the ODF parser, which currently accepts
  only the font-relative measures and forces fallback in other cases.
* Added loext:text-indent to the ODF parser. This attribute accepts
  font-relative metrics, and will behave as an import-only alias for
  fo:text-indent in other cases.
* Updated SvxFirstLineIndentItem to handle unit-denominated measures.
* Added proof-of-concept indentation handler to Writer. This
  implementation is incomplete and temporary, and will be revised in
  future changes.
