Fix a bug in qdocs handling of excludedirs

The bug was there because the way qdoc tries to exclude the directories
given in the "excludedirs" variable:
It did a simple string comparision on the candidate path (to include)
with every string in the "excludedirs" variable.

However, this did not work for all cases, since the paths are not
canonicalized.
For instance, the problem I faced was that the following qdocconf
fragment: (config file located in doc/qtwidgets.qdocconf)
sourcedirs  += ..
excludedirs += snippets

Since qdoc would recursively parse all subfolders of sourcedirs, it
would at one point visit the snippets folder, but it would have the
relative path "../doc/snippets", which did not match with "snippets",
causing snippets to not be excluded.

In addition, it seems that qdoc tries hard not to use absolute paths
(maybe because of more human-friendly error messages). I therefore
chose to canonicalize the relative paths.

As a side-effect this also give a better output from qdoc, as
../doc/foo.qdoc:42: Missing link
will become
foo.qdoc:42: Missing link

QNX: Allow app to run when spurious 2nd screen is reported

On the PlayBook, libscreen always seems to report the presence of a 2nd
display even when none is connected. This of course leads to the failure
to query this display for its physical size.

qmake: support incremental linking when embedding manifests

When embedding manifests we modified the EXE/DLL after linking using
the manifest tool. This breaks the incremental linking feature of MSVC.

The MS way to embed a manifest without breaking incremental linking is:
   - let the linker create the manifest file,
   - create a resource that contains the manifest file,
   - invoke the linker again to embed the resource.

The embed_manifest_{exe|dll}.prf files have been removed.
All manifest logic is now in qmake's nmake makefile generator.

With QMAKE_MANIFEST one can specify a custom manifest file that gets
embedded without disturbing incremental linking.

QSlotObjectBase: combat virtual function "bloat"

In C++, the compiler creates extra functions and data for classes
with virtual functions. This can lead to "virtual function bloat":
  http://www.boost.org/doc/libs/1_47_0/doc/html/function/misc.html#id1382504

This is especially true when the number of instances is of the same
order of magnitute as the number of derived classes, such as is
common with type erasure techniques.

One such case is the QSlotObjectBase hierarchy, which this patch
tackles.

The mechanics of this optimisation are simple: re-implement the
virtual function call mechanism by hand, with function pointers.

But we go one step further and collapse the vtable into a single
pointer to a function that implements all three currently-defined
operations, swtching on an 'int which' argument. This even allows
us to extend this in a BC way, should that become necessary later,
by adding a new Operation and using the void** argument to
transport arguments, if any.

This approach was inspired by:
  Ulrich Drepper: How To Write Shared Libraries, Section 2.4.4
  http://www.akkadia.org/drepper/dsohowto.pdf

Also move the QSlotObjectBase hierarchy out of QObject so as not
to export all the derived classes.

This was pointed out in review by Thiago.

Avoid an expensive call to toLocal8Bit upon thread creation

Disable CPUID checking with GCC 4.2 or older

This is not the first time that GCC 4.2 on Mac has produced bad code
surrounding the CPUID instruction (see also commit 81d1f79a7f4b0f67d71).
So declare it broken beyond repair and don't run the instruction at all.

Instead, initialise the set of features found to be exactly that which
we detected at compile-time. For that reason, we can also disable the
runtime checking of the processor (minFeatures == detected features).

At the time of this commit, only the draw helpers and one QImage
helper make use of the runtime detection. Since the detection now
switches to compile-time, QtGui will start carrying dead code for GCC
4.2 and earlier: it will never run the SSE2/SSSE3 code on 32-bit
builds. (GCC 4.2 does not support AVX, so that code won't be built)

Note: all Clang versions report that they are GCC 4.2, so we need to
exclude it from the test; ICC reports the same version as the system's
GCC.
