bded052aad Windows: Do not link QtCore against ICU by default
Do not link against ICU on Windows, unless it is explicitly requested
('-icu' configure option). This removes the QtCore->ICU dependency
if ICU was detected in the configure environment.

So far ICU has been used in Qt Core for

- support of a larger set of codecs (805 instead of 135)
- more accurate QLocale functionality (QLocale::toUpper,
  qLocale::toLower)
- string collation

However, for all functionality there are also backends using the
Windows API/Registry (QLocale, QCollator), or built-in
codecs that are part of QtCore. Since the ICU dependency is quite heavy
(3 libs with about 25 MB) it seems sensible to not require it by default.

QtWebkit is unaffected, since it has it's own ICU check.

[ChangeLog][Windows] Changed configure defaults so that Qt5Core does not
link against ICU libraries anymore. Pass '-icu' to enable it.

ecf6aa2dca configure: Disable XCB auto-detection on Mac
Users might have (old) libxcb installed on OS X, for instance as
a dependency for another package installed via MacPorts. It's still
very unlikely that any Mac user would want to use the XCB platform
plugin. Thus, disable the auto-detection to avoid a dubious XCB
configuration error on Mac.

f81de3944d Support logging direct to journald, if enabled.
Instead of merely intercepting logging output from stdout/stderr from the
journal side of started processes, this has the advantage of meaning that the
origin process name will be correct.

fprintf won't work, because if a process starts children (like e.g. a
homescreen does), then their stdout/stderr are merged into their parent, and
journal has no way of differentiating the origin.

We are also able to store information about the context of logging, which might
be useful in post-mortem cases.

[ChangeLog][Platform Specific Changes][Linux] Systems with systemd may now pass
-journald to configure to send logging output to journald. Logging will still be
sent to stderr for interactive applications (run from a tty) or with
QT_NO_JOURNALD_LOG set to a non-empty value.

Passing -no-xcb disables xcb and related configuration tests
completely so for example QT_NO_XRENDER is not defined.  This results
in linker errors in glxconvenience with -no-xcb since the XRender
calls are compiled in without linking to the library.

The XRender, XInput and such tests are not strictly xcb related and
may be used from elsewhere, for example glxconvenience which has
nothing to do with xcb. Therefore these tests are moved in configure
so that they are run even when xcb is disabled.
