8450ab8dec CMake: Make gui tests standalone projects
Add the boilerplate standalone test prelude to each test, so that they
can be opened with an IDE without the qt-cmake-standalone-test script,
but directly with qt-cmake or cmake.

Boilerplate was added using the following scripts:
https://git.qt.io/alcroito/cmake_refactor

Manual adjustments were made where the code was inserted in the wrong
location.

3f40a8b5b1 Add QTextListFormat::start: html and markdown ordered list index offset
This is useful for a lot of applications that render text coming from
sources which already support arbitrarily numbered lists (like chat
applications for example). Application-side workarounds usually have
significant overhead; and this feature has been requested multiple times.

It should be possible to both read and write HTML with the <ol start="x">
attribute, and read and write Markdown with arbitrary numbers for the
first item in a list.

[ChangeLog][QtGui] QTextList now supports specifying a start index using
the new QTextList::{setStart, start} functions. The HTML start attribute
on ordered lists in rich text documents is now parsed and used when
rendering a text list. Non-negative indices in markdown lists are now
also parsed and written properly. This allows starting a list with a
different number than 1.

846b314aaf Emit autolinks in QTextMarkdownWriter
When a markdown document contains a "naked" URL, or an angle-bracketed
<URL>, md4c recognizes it, and we set the AnchorHref charfmt property.
There's no need to expand it into the [text](url) form if the text is
the same as the url, there is no tooltip, and the url is valid.
QTextMarkdownWriter now writes a CommonMark "autolink" in that case:
https://spec.commonmark.org/0.30/#autolinks

[ChangeLog][QtGui][Text] QTextMarkdownWriter now writes an autolink
whenever a hyperlink has no custom text and no tooltip, including
when the document was parsed from Markdown containing a naked URL.

04a60bb033 Convert <pre> to Markdown ``` and vice-versa with nonBreakableLines
The HTML parser calls QTextBlockFormat::setNonBreakableLines(true) when
it sees a <pre> tag; so for symmetry, the markdown reader now does the
same when it sees a fenced code block, and the markdown writer honors
the nonBreakableLines property by writing a fenced code block. This
preserves the meaning better when reading HTML and writing markdown or
vice-versa, without modifying HTML reading or writing code.

Added a test tst_QTextMarkdownImporter::fencedCodeBlocks() which
unfortunately also highlights a known bug in the markdown reader: each
fenced code block ends with an extra empty block. That can be fixed
separately.

tst_QTextMarkdownWriter::fromHtml(preformats with embedded backticks)
that we re-enabled in 1abaf9d5d6 was not a
very useful test: ``` with a space and some words but no newline is not
a fence: it's just like a `monospace` span. We have had trouble with
those in CI because of missing monospace fonts, or inconsistency when
a supposedly mono font's QFontInfo::fixedPitch() returns false.
So just test proper <pre>/fence conversion for now.

1ad456c908 Un-blacklist markdown tests: QSKIP when fonts are scrambled
On QNX in CI we see
system fonts: fixed: monospace 9; general: Sans Serif 9
and "monospace" isn't really a fixed pitch font.
On B2Qt arm7 in CI we see
system fonts: fixed: monospace 9; general Sans Serif 9
and Sans Serif is actually fixed pitch.

So these tests can go wrong both ways; we need to skip them whenever
the fonts would lead QTextMarkdownWriter astray.

5e55297ee0 Markdown writer: indent fence consistent with code block
- Under a list item, we've been indenting code blocks:
  ```
  int main() ...
  ```
- But it's also ok *not* to indent (and github handles that better):
```
int main() ...
```
- There was a bug that when the code is not indented, the fence would be
  indented anyway:
  ```
int main() ...
  ```
  and that was not OK, neither for md4c nor for github.

Now with this change, either way is rewritable: you can read markdown
into QTextDocument, make small edits and write it back out again, with
the indentation being preserved (the code block is either part of the
list item, thus indented, or else it's outside the list completely).

b3cc9403c4 QTextMarkdownWriter: write fenced code blocks with language declaration
MD4C now makes it possible to detect indented and fenced code blocks:
https://github.com/mity/md4c/issues/81
Fenced code blocks have the advantages of being easier to write by hand,
and having an "info string" following the opening fence, which is commonly
used to declare the language.

Also, the HTML parser now recognizes tags of the form
<pre class="language-foo">
which is one convention for declaring the programming language
(as opposed to human language, for which the lang attribute would be used):
https://stackoverflow.com/questions/5134242/semantics-standards-and-using-the-lang-attribute-for-source-code-in-markup
So it's possible to read HTML and write markdown without losing this information.

It's also possible to read markdown with any type of code block:
fenced with ``` or ~~~, or indented, and rewrite it the same way.

280d679c55 QTextMarkdownWriter: fix some bad cases with word wrap
If any non-breakable content (such as a link) already went past
80 columns, or if a word ended on column 80, it didn't wrap the rest of
the paragraph following.

7224d0e427 QTextMarkdownImporter: don't keep heading level on following list item
When reading a document like

 # heading
 - list item

and then re-writing it, it turned into

 # heading
 - # list item

because QTextCursor::insertList() simply calls QTextCursor::insertBlock(), thus
inheriting block format from the previous block, without an opportunity to
explicitly define the block format.  So be more consistent: use
QTextMarkdownImporter::insertBlock() for blocks inside list items too.  Now it
fully defines blockFormat first, then inserts the block, and then adds it to
the current list only when the "paragraph" is actually the list item's text
(but not when it's a continuation paragraph).  Also, be prepared for applying
and removing block markers to arbitrary blocks, just in case (they might be
useful for block quotes, for example).

7dd71e8125 Markdown: blockquotes, code blocks, and generalized nesting
Can now detect nested quotes and code blocks inside quotes, and can
rewrite the markdown too.

QTextHtmlParser sets hard-coded left and right margins, so we need to do
the same to be able to read HTML and write markdown, or vice-versa,
and to ensure that all views (QTextEdit, QTextBrowser, QML Text etc.)
will render it with margins.  But now we add a semantic memory too:
BlockQuoteLevel is similar to HeadingLevel, which was added in
310daae539 to preserve H1..H6 heading
levels, because detecting it via font size didn't make sense in
QTextMarkdownWriter.  Likewise detecting quote level by its margins
didn't make sense; markdown supports nesting quotes; and indenting
nested quotes via 40 pixels may be a bit too much, so we should consider
it subject to change (and perhaps be able to change it via CSS later on).
Since we're adding BlockQuoteLevel and depending on it in QTextMarkdownWriter,
it's necessary to set it in QTextHtmlParser to enable HTML->markdown
conversion.  (But so far, nested blockquotes in HTML are not supported.)

Quotes (and nested quotes) can contain indented code blocks, but it seems
the reverse is not true (according to https://spec.commonmark.org/0.29/#example-201 )

Quotes can contain fenced code blocks.

Quotes can contain lists.  Nested lists can be interrupted with
nested code blocks and nested quotes.

So far the writer assumes all code blocks are the indented type.
It will be necessary to add another attribute to remember whether the
code block is indented or fenced (assuming that's necessary).
Fenced code blocks would work better for writing inside block quotes
and list items because the fence is less ambiguous than the indent.

Postponing cursor->insertBlock() as long as possible helps with nesting.
cursor->insertBlock() needs to be done "just in time" before inserting
text that will go in the block.  The block and char formats aren't
necessarily known until that time.  When a nested block (such as a
nested quote) ends, the context reverts to the previous block format,
which then needs to be re-determined and set before we insert text
into the outer block; but if no text will be inserted, no new block
is necessary.  But we can't use QTextBlockFormat itself as storage,
because for some reason bullets become very "sticky" and it becomes
impossible to have plain continuation paragraphs inside list items:
they all get bullets.  Somehow QTextBlockFormat remembers, if we copy it.
But we can create a new one each time and it's OK.

82b26444a4 Change QTextMarkdownWriter to pass by const pointer and QAIM
- QObjects are always passed by pointer not by reference, by convention
- writeTable() takes QAIM rather than QATM to make testing via
  QStandardItemModel possible in the future

040dd7fe26 Markdown: fix several issues with lists and continuations
Importer fixes:
- the first list item after a heading doesn't keep the heading font
- the first text fragment after a bullet is the bullet text, not a
  separate paragraph
- detect continuation lines and append to the list item text
- detect continuation paragraphs and indent them properly
- indent nested list items properly
- add a test for QTextMarkdownImporter
Writer fixes:
- after bullet items, continuation lines and paragraphs are indented
- indentation of continuations isn't affected by checkboxes
- add extra newlines between list items in "loose" lists
- avoid writing triple newlines
- enhance the test for QTextMarkdownWriter

23c2da3cc2 Add QTextMarkdownWriter, QTextEdit::markdown property etc.
A QTextDocument can now be written out in Markdown format.

- Add the QTextMarkdownWriter as a private class for now
- Add QTextDocument::toMarkdown()
- QTextDocumentWriter uses QTextMarkdownWriter if setFormat("markdown")
  is called or if the file suffix is .md or .mkd
- Add QTextEdit::toMarkdown() and the markdown property

[ChangeLog][QtGui][Text] Markdown (CommonMark or GitHub dialect) is now
a supported format for reading into and writing from QTextDocument.
