layoutLines() trimmed the trailing spaces of every line and kept
non-breaking spaces, which the DXF export used to write as plain spaces
(toPlainText()). A DXF R10 file has no code page, so a reader assuming
Windows-1252 could show them as 'Â '. Now a paragraph that does not
wrap gives exactly its line of toPlainText().split('\n') again
(trailing spaces and tabs kept, non-breaking spaces as plain spaces,
<br> as a line break). In a paragraph that wraps, every line loses its
trailing spaces, so spaces that wrap to a line of their own give an
empty line: not written, but it keeps the spacing of the next lines.
Test: tst_textlines compares with toPlainText() for trailing spaces,
tabs, non-breaking spaces, <br> and paragraphs, and checks wrapped
lines (fails before).

A symbol text with a width (text_width) is drawn wrapped on the folio,
but the DXF export split texts on '\n' only, so it was written as one
long line, running past its box and over the drawing. The export now
writes the lines of folio texts as they are laid out
(TextLines::layoutLines(), new header-only textlines.h). Texts without
a width give the same lines as before.
Tests: tst_textlines, tst_dxfwrappedtext (fails without this change).
