Subject: [PATCH 1/5] Shared: add function combining lines using LineBreak

The `linesToBlock` function takes a list of lines and combines them by appending
a hard `LineBreak` to each line and concatenating the result, putting the result
it into a `Para`. This is most useful when dealing when converting `LineBlock`
elements.

Subject: [PATCH 2/5] Add support for the LineBlock element to writers

The following markup features are used to output the lines of the `LineBlock`
element:

  - AsciiDoc: a `[verse]` block,
  - ConTeXt: text surrounded by `\startlines` and `\endlines`,
  - HTML: `div` with an per-element style setting to interpret the content as
    pre-wrapped,
  - Markdown: line blocks if the `line_blocks` extension is enabled, a simple
    paragraph with hard linebreaks otherwise,
  - Org: VERSE block,
  - RST: a line block, and
  - all other formats: a paragraph, containing hard linebreaks between lines.

Custom lua writers should be updated to use the `LineBlock` element.

Subject: [PATCH 3/5] Parse line-oriented markup as LineBlock

Markup-features focusing on lines as distinctive part of the markup are read
into `LineBlock` elements. This currently means line blocks in reStructuredText
and Markdown (the latter only if the `line_block` extension is enabled), the
`linegroup`/`line` combination from the Docbook 5.1 working draft, and Org-mode
`VERSE` blocks.
