This commit removes the previous version of the bundled
libpng (1.5.4), as well as all local modifications to it.
It adds an unmodified copy of the official libpng
source distribution, except that various extraneous
files have been removed, as usual.
The patches required to build it in Qt will follow in
separate commit(s).

WEC7 mkspecs define _CRT_SECURE_NO_DEPRECATE globally. libpng redefined
the same macro without checking if it is already defined. Added #ifdef
guard for libpng '_CRT_SECURE_NO_DEPRECATE' macro definition.

If qt is compiled with -qt-libpng then the png symbols
prevent a loading of another libpng. With this patch
the png symbols are hidden and thus it is possible
to load another libpng.

The PNG Development Group explains that libpng 1.5.4 (only) introduced
a divide-by-zero bug in png_handle_cHRM(), which could lead to crashes
(denial of service) for certain malformed PNGs.

This commit contains the patch recommended by the PNG Development
Group, ref. http://www.kb.cert.org/vuls/id/477046

The upgrade of the bundled libpng to version 1.5 had the side effect
of causing the png functions to be exported from the QtGUi DLL
when built with the MS Visual C++ compiler.

This is a clean copy of the official libpng 1.5.4 distribution, except
that various extraneous stuff (examples, tests, etc) have been
removed, as usual. The minor modifications to build it in Qt will
follow in a separate commit.

This reverts commit 4dd03abdfbcc1af3075b30165e19ee63fe8051f4. And changes
stl.prf slightly to get the Qt libs compiled again without reverted hack.

This makes Qt work on VxWorks 6.6+ in native (kernel) mode.
* compiles with the WindRiver GNU toolchain (Linux only)
* works with QWS (tested with the VNC driver only)
* tested on PPC hardware and the x86 VxWorks simulator
* no q3support, no phonon, no webkit
* no QSharedMemory, no QSystemSemaphore, no QProcess
* only one QApplication instance (flat address space)
* filesystem support depends heavily on the quality of the native driver
* QLibrary is just a dummy to make plugins work at all
* qmake transparently creates VxWorks munching rules for static ctors
* made auto-test cope with missing OS features
A special note regarding the Q_FOREACH patch for dcc:
when calling foreach(a,c) with c being a function returning a container,
the compiler would generate 5 references to some labels (.LXXXX), which
are not there (so the linker complains in the end).
Seems like dcc doesn't really like the 'true ? 0 : <function call to get type>'
statement
