Extract header qassert.h from qglobal.h

For now qassert.h is included in the middle of qglobal.h, since some of
the code below needs it, but this will be cleaned up when that code is
moved in its own header.

+    \macro void Q_ASSERT(bool test)

+
+    Prints a warning message containing the source code file name and
+    line number if \a test is \c false.
+
+    Q_ASSERT() is useful for testing pre- and post-conditions
+    during development. It does nothing if \c QT_NO_DEBUG was defined
+    during compilation.
+
+    Example:
+
+    \snippet code/src_corelib_global_qglobal.cpp 17
+
+    If \c b is zero, the Q_ASSERT statement will output the following
+    message using the qFatal() function:
