The order of them are important while the uniqueness has nothing to do
with the compiling.

commit 2c5eea4c in upstream.

rename template.vcproj to template_vs2005.vcproj
add template_vs2012.vcxproj
NOTE: the vs2012.py is ugly, just can work.

The `clang -fsyntax-only` will give us additional warning messages in
the console.

It adds the '--clang-analyzer' option that could invoke clang as the
static code checker. It is recommanded to work with 'scan-build' shipped
with Clang. For example, `scan-build scons --clang-analyzer`.

When --cscope option is given to Scons, it will generate a cscope
cross-reference database in current directory, which is useful in
Vim(and other cscope-aware text editors). For example, `scons -s
--cscope` will do nothing except generating the database. You can use
this option with other options together.

It is inspired by the `make cscope` of Linux.

The return type of SConscript is a subclass of UserList. We should use
extend to keep the depth of the list is always 1 when concatenate
SConscript return values. Thanks prife for making me realize that this
is really a problem.

One could register a callable object(normally a function) via RegisterPreBuildingAction in SConscript. It will be called when PreBuilding get invoked. PreBuilding should be called before the building procedure. It is currently used by RTGUI to generate the minimal perfect hash code when all the source files are scanned(i.e. just before building).

Maybe we should invoke PreBuilding in DoBuilding.

If one do not want to use some components in the RTT_ROOT, it can pass a remove_components=['the_component'] parameter to PrepareBuilding. Sample code is:

RTT_RTGUI = os.getenv('RTT_RTGUI')
# if GUI dir is set to other place, don't use the one in RTT_ROOT
if RTT_RTGUI:
    # prepare building environment
    objs = PrepareBuilding(env, RTT_ROOT, has_libcpu=False, remove_components=['rtgui'])
    objs += SConscript(os.path.join(RTT_RTGUI, 'SConscript'))
else:
    objs = PrepareBuilding(env, RTT_ROOT, has_libcpu=False)

You can safely omit the parameter if you do not want to remove any components.

fix bugs in building.py that is when DefineGroup method's 3rd arges "CPPDEFINES" is not null, then "scons --target=mdk -s" will get errors.
