In QML, one can use XMLHttpRequest. Not so with a plain JS engine. The
reason for that lies in the fact that a JS engine did not have any
network access, because all network functionality was in the type
loader, and the type loader was coupled to the QV4::Engine.
This has changed in d2bc4a4330254c0c68a0ade51b59a71c4b67b470, but we
stil don't expose XMLHttpRequest to a plain QJSEngine.
Nevertheless, it conceptually lives in the global object, and we need to
collect information about it to enable code completion and linting.
Consequently, expose a function in QV4::Engine, which allows us to
manually trigger the registration, and call it in qmljsrootgen.
Going forward, we should arguably have a QJSEngine::Extension for
XMLHttpReuqest, after which we could remove the hack.
Note that as before, qmljsrootgen prints a few warnings, because we call
functions in contexts in which they must not be called. As before, we
ignore this for now.
As a side-effect, this adds a few more entries to the qmltypes file for
new entries on the global Qt object.

Use QHash/QMap's constFind() instead of non-const find() where
applicable to avoid unnecessary detaches.

Additionally, improved the error message for missing output path.

This is a semantic patch using ClangTidyTransformator to convert
sequences of Q_UNREACHABLE() + return into Q_UNREACHABLE_RETURN(),
newly added to qtbase.
const std::string unr = "unr", val = "val", ret = "ret";
auto makeUnreachableReturn = cat("Q_UNREACHABLE_RETURN(",
ifBound(val, cat(node(val)), cat("")),
")");
auto ignoringSwitchCases = [](auto stmt) {
return anyOf(stmt, switchCase(subStmt(stmt)));
};
makeRule(stmt(ignoringSwitchCases(stmt(isExpandedFromMacro("Q_UNREACHABLE")).bind(unr)),
nextStmt(returnStmt(optionally(hasReturnValue(expr().bind(val)))).bind(ret))),
{changeTo(node(unr), cat(makeUnreachableReturn,
";")), // TODO: why is the ; lost w/o this?
changeTo(node(ret), cat(""))},
cat("use ", makeUnreachableReturn));
a.k.a qt-use-unreachable-return.
subStmt() and nextStmt() are non-standard matchers.
There was one false positive, suppressed it with NOLINTNEXTLINE.
It's not really a false positiive, it's just that Clang sees the world
in one way and if conditonal compilation (#if) differs for other
compilers, Clang doesn't know better. This is an artifact of matching
two consecutive statements.

They're not needed for the inlining of Math methods in qmlcachegen.
qmlcachegen itself detects the Math object and its methods and assumes
they shall always deal with numbers.
Furthermore, the types in jsroot.qmltypes are actually wrong. Using JS
"number" does not help here because we need C++ types.

Previously calling a JavaScript function with variable arguments could
cause the linting process to error out because of a lack of matching
function arguments.
This is now handled by defaulting to a JavaScript method if no matching
function signature can be found.

This gives us type information for a few extra properties, among which
is ArrayBuffer. We also declare ArrayBuffer as extension to QByteArray,
which we can now test with qmllint.

Methods on the "Math" object preferably deal with numbers, and if we
pass them numbers, they also return numbers. Model this as overrides of
the generic methods.

This way it actually generates interesting data about the JavaScript
types, for example the functions of the String prototype. Add a helper
method to create a symbol to QJSEngine. This should be generally useful.

This change adds jsroot.qmltypes which represents QJSEngine's global / root object and a tool to generate it (qmlsjrootgen).
If you wish to regenerate jsroot.qmltypes run the following commands:
qmljsrootgen jsroot.json
qmltyperegistrar jsroot.json --generate-qmltypes src/imports/builtins/jsroot.qmltypes --import-name QJSEngine --major-version 1 --minor-version 0
