Some systems (e.g. musl) do not have execinfo.h header.
Check if libexecinfo (library that provides execinfo.h header
and its functions) is installed in the system, and add
its linker flag if needed.
With localization for non-Latin languages on the support list the multibyte API doesn't cut it anymore. It neither can handle system text output outside the local code page nor can an ANSI window receive text input outside its own code page.
Similar problems exist for file names. With the multibyte API it is impossible to handle any file containing characters outside the active local code page.
So as of now, everything that may pass along some Unicode text will use the Unicode API with some text conversion functions. The only places where calls to the multibyte API were left are those where known string literals are passed or where the information is not used for anything but comparing it to other return values from the same API.

clang: warning: libstdc++ is deprecated; move to libc++ with a minimum deployment target of OS X 10.9

- Added: d_main.cpp now searches for "gzdoom_optional_assets.pk3" - this can be changed in version.h for fork authors.
- Updated forum links to point to ZDoom.org.
- optimized the math to get a plane equation from a linedef. The original code used a generic algorithm that knew nothing about the fact that Doom walls are always perfectly vertical. With this knowledge the plane calculation can be reduced to a lot less code because retrieving the normal is trivial in this special case.
- use the SSE2 rsqrtss instruction to calculate a wall's length, because this is by far the most frequent use of square roots in the GL renderer. So far this is only active on x64, it may be activated on 32 bit later as well, but only after it has been decided if 32 bit builds should be x87 or SSE2.

Since the true color software renderer also handles them there is no point keeping them on the GL side.
This also optimized how they are stored, because we no longer need to be aware of a base engine which doesn't have them.
- Worked aorund modern GCC bug where C++ exceptions in Objective-C++ code would result in an ICE (bug is already on their tracker, but I doubt it will be fixed unless I decide to dig into the issue myself).
- Turn off fused floating point instructions since these can cause slight deviations in floating point code.
- Use -static-libgcc when compiling on the Mac with GCC since we need to use a custom version of GCC to do so now.
- Note: ZDoom will currently still crash on exit on PowerPC since it seems to be deciding that NameManager needs to be destructed before the console commands.
