( @Akien : this PR is for current HEAD only, not to be cherry-picked for 2.1.1 )
this is manual revertion of #6501 which introduced a bug that prevented
scons from detecting Mingw under Windows when MSVC was installed.
(thanks to @vnen for finding this)
AND
it fixes the actual bug that prevented scons from detecting MSVC standalone
compiler ( a confusions between ``VSINSTALLDIR`` and ``VCINSTALLDIR`` )
The freeware Standalone MSVC C++ Build Tools are available here :

Not fully happy about the way this one interacts with the various
platforms. Maybe the platform_config.h should be generated by the
SCsub instead of passing a define just to know where is the header.
Took the opportunity to undo the Godot changed made to the
opus source. The opus module should eventually be built in its
own environment to avoid polluting others with too many include
dirs and defines.
TODO: Fix the platform/ stuff for opus.
They are not particularly packaged in Linux distros so we do not
facilitate unbundling via SCons. There could be done if/when there
is interest.
Also s/pnm/pbm/, long-lived typo :)
Uses the new structure agreed upon in #6157, but the thirdparty/ folder
does not behave following a logic similar to that of modules/ yet.
The png driver can't be moved to a module as discussed in #6157, as it's
required by core together with a few other ImageLoader implementations
(see drivers/register_driver_types.cpp:register_core_driver_types())
Dropped the possibility to disable PNG support, it's a core component
of Godot.
As mentioned by upstream, Xiph.Org [0]:

Under Windows, Scons is now capable of detecting and compiling with
standalone MSVC compilers (aka "Visual C++ Build Tools").
http://landinghub.visualstudio.com/visual-cpp-build-tools
Tried with version 2015, and native x86 and x64 compilers under
Windows 10 pro 64 and Windows 8.1 64, with the default Win8 SDK
provided by the "Visual C++ Build Tools" web-installer.
Follow the same compiling instructions than for compiling with Visual
Studio, except that Visual Studio is no more required.
KNOWN ISSUES :
- ``methods.detect_visual_c_compiler_version()`` will emit a warning message
on computers where the ``VSINSTALLDIR`` environement variable is not present.
But it should compile just fine and still automatically detects the 32 or
64 bits according to the compiler you picked.
TODO :
- eventually, update ``platform/winrt/dectet.py`` with function
``methods.msvc_is_detected()`` and try to compile winrt/UWP with
these standalone compilers (if you did not select Win10 SDK when
installing the standalone tools, you can run it again).
- update doc to make users aware of "Visual C++ Build Tools" aka
"stadalone MSVC".
- eventually, update ``methods.detect_visual_c_compiler_version()``
NMake was not setup by the vsproj=yes compilation
parameter. After attempting other possible options,
this is the best fix for our current requirements.
Compiling via NMake is implementing an alternative
to SCons, so this fix escapes out of NMake
environment while also supporting different target
builds and IDE error list integration.
Also sets -j setting to 2 so that it's easy for
people to change it to a propper value and speed it
up a bit for those that do not.
Adds two missing .gitignore Visual Studio temp files
present in Visual Studio's .gitignore.
