The ODT reader is supposed to detect blockquotes by checking a paragraph
style's indentation level. But it's broken for two reasons:
* The parser fails on non-integers. So "1in" will get read as 25mm, but
"1.0in" fails. By default, the Quotations style is "0.3937in".
* The reader doesn't check indentation levels of parent styles.
In my test documents, LibreOffice often creates child styles for
individual paragraphs, so it's important to check parents (ODT files
created by the Pandoc ODT writer don't have this issue though).
I added a new test "blockquote2" whose ODT file is generated directly
from the corresponding Markdown file with pandoc.
Fixes#3437.
- Writers.Native is now adapted to the new Table type.
- Inline captions should now be conditionally wrapped in a Plain, not
a Para block.
- The toLegacyTable function now lives in Writers.Shared.
