I'm getting crashes in Akonadi processes due to libproxy. I don't have
direct evidence that this was caused by a threading condition, but it's
clear from the source code of libproxy that the plugins it runs for
expanding PAC scripts are not thread-safe. To overcome this problem, we
only run libproxy functions in one thread only.

The pacrunner implementation of libproxy uses libdbus-1 which
(officially) is thread-safe, but experience tells that it has
problems. Since it is not running a JS engine, we don't need a thread,
but we do need to lock around it.

A macro name ending in R might expand to a string; if this precedes a
string constant, we're juxtaposing the strings. My first parser for
raw strings would mistake it for a raw string instead, ignoring the
part of the identifier before R. Re-worked the exploration of what
came before the string to catch these cases, too.
The backwards parsing would also allow any messy jumble of [RLUu8]* as
prefix for the string; but in fact R must (if present) be last in the
prefix and *it* can have at most one prefix, [LUu] or u8. Anything
else is an identifier that happens to precede the string. Reworked
the parsing to allow only one prefix and not treat R specially unless
it's immediately (modulo BSNL) before the string's open-quotes.
Add link to the cppreference page about string literals, on which the
grammar now parsed is based.
Added a test for the issue this addresses.
Verified that this fails on 5.6, dev and 5.9 without the fix.
Expanded the existing test to cover R-with-prefix cases.

When calling resize() from showEvent(), we'd set the full geometry
on the widget's QWindow. This resulted in the top-level window
being moved to the top-left corner, even though no other call to
move() or setGeometry() had happened before.
The solution consists on calling the proper QWindow methods depending
on whether setGeometry_sys() is called for a move, a resize or both.
Furthermore, this needs QWindow::resize() to set its position policy
to frame-exclusive. The documentation states that is already the case
and we're setting the full geometry on the platform window, so we need
to convey that bit of information.
This also solves the age-old conundrum: "### why do we have isMove as
a parameter?"
