Added -datatags option to QTestLib

(Note: This feature is ported from Qt 4.8.
 See the following commits:

)

Passing the -datatags option to a QTestLib program prints the
available data tags to standard output.

For completeness, the test case name is also printed
at the start of each output line. (Although the file name
is supposed to match the lower-case version of the test case
name, this is currently not true in all cases (particularly not
under tests/benchmarks/). Even if there was a script to enforce this
convention, the -datatags option provides this information in a
reliable way.)

Data tags for each test function (f() in this case) are printed in
four different ways depending on the presence of local and global
data tags:

Case 1: No tags:
    tst_MyTestCasetst_MyTestCase f

Case 2: Local tags only:
    tst_MyTestCase f local tag 1
    tst_MyTestCase f local tag 2
    ...

Case 3: Global tags only:
    tst_MyTestCase f __global__ global tag 1
    tst_MyTestCase f __global__ global tag 2
    ...

Case 4: Local and global tags:
    tst_MyTestCase f local tag 1 __global__ global tag 1
    tst_MyTestCase f local tag 2 __global__ global tag 1
    ...
    tst_MyTestCase f local tag 1 __global__ global tag 2
    tst_MyTestCase f local tag 2 __global__ global tag 2
    ...
    ...

Note that the string __global__ is assumed to be highly unlikely to occur
in a data tag (if it does, an ambiguity results).
