b0afad8f0b Implement support for ref-qualified QString::toLatin1 & friends
This is the first step in implementing an in-place conversion of QString
to QByteArray. This requires ref-qualifiers in member functions so we
know that we have an rvalue QString.

Converting from UTF-16 to Latin1 always requires half the memory.

For conversion from UTF-16 to UTF-8, the typical string will also need
the same memory or less: characters from U+0000 to U+007F consume one
fewer byte; characters from U+0080 to U+07FF and from U+10000 to
U+1FFFFF occupy the same space in UTF-8 and UTF-16; it's only the ones
from U+0800 to U+FFFF that consume more space in the UTF-8 string.

For the locale's 8-bit codec, we can't be sure and the code (currently)
needs to go through QTextCodec anyway.

This requires a #define set before #include'ing "qstring.h". However,
since qstring.h is included by the QtCore PCH, we need an extra qmake
compiler without the PCH flags to compile this .cpp.

After this change, the distribution of calls in QtCore, Network, Gui,
and Widgets is as follows:

                  const &               &&
 toUtf8           31 (74%)              11 (26%)
 toLatin1         79 (77%)              24 (23%)
 toLocal8Bit      26 (16%)              138 (84%)

9c2ec72b95 Improve path search in configure.
- Remove duplicated code locateFile/locateFileInPaths.
- Move basic path search functionality to Environment.
- Add functions for headerPaths/libraryPaths to  Environment.
- Use QStandardPaths::findExecutable().
- Replace Environment::detectExecutable by
  QStandardPaths::findExecutable().
- Introduce static path lists in findFile() to avoid
  repeated directory scans

7395e6abc6 Clean up the use of QT_NODLL
QT_NODLL is replaced by QT_STATIC, but the latter is implied if
QT_BOOTSTRAPPED is already defined. Therefore, simply remove the
QT_NODLL definitions.

6ab6b0fc1c Disable QUrl support in QVariant in bootstrapped mode
The only use of QUrl in qmake, moc, uic and rcc is due to QVariant's
internals, so let's disable it. This means those binaries are now
probably a lot smaller since the parsing and IDNA code don't need to
be present.

90feedb642 bootstrap configure.exe on windows
it is *ugly* to have the binary in the repository.
this adds a few seconds to the windows build, as the configure needs to
be rebuilt, obviously. that's almost negligible.
