the replacement value may well constitute the whole output string - this
is in fact common, given this rather typical usage pattern:
BAR = $$replace(FOO, -flag, -otherflag)
this must be considered when constructing the return value.
compare 3c8134958c.
as of now, this is irrelevant, as QString::replace(QRegExp, QString) will
always memcpy the replacement into a detached copy of the target, but one
never knows.

it's not clear why detaching would be necessary; there is no danger of a

concatenating a QStringRef with a non-empty QLatin1String (the only
expected use of this overload) will yield a detached QString anyway, so
this makes little difference in practice.

QRegExp saves a copy of the matched string, so it's necessary to
alternate between two temporaries to avoid detaching. we already

The strings remember in which file they were created/assigned.
However, this used a non-counting reference to a ProFile, which could
become dangling. If a subsequent ProFile re-used the exact same address,
a string's source would be mis-identified, which would be fatal in
conjunction with discard_from().
Since we actually need only a unique id for comparison, let's use an
integer for that.

the arguments after '--' are by definition meant only for the top-level
project, as that's where configure is invoked from. passing them to
sub-projects just adds noise to the make output and misleads users.
note that this specifically does not support qmake -r, which will break
if the subprojects rely on the arguments being absent. this isn't a
problem, because the qt build doesn't support qmake -r anyway.

this moves us another step towards the "outer" configure doing just
minimal bootstrapping of qmake.
a challenge here was that so far, qmake itself needed qconfig.cpp. this
was replaced by usage of a qt.conf file instead of compiled-in values.
however, to make the executable still self-contained, that qt.conf is
embedded into it (by simple appending of a fixed signature and the text
file).
the qmake with the embedded qt.conf is not used for the qt build itself,
which instead relies on the qt.conf in bin/ as before. however, due to
the missing built-in values, this file now needs to contain more
information than before. but except for a minimal version that is needed
to start up qmake/configure at all, that file is now also generated with
qmake. as some of the newly set up properties are subsequently used by
configure itself, qmake gains a (deliberately undocumented) function to
reload the qt.conf after it's fully populated.
unlike the old implementations, this one doesn't emit redundant qt.conf
entries which match the hard-coded fallbacks. omitting them leads to
leaner files which are more comprehensible.
