When building on CentOS 8 with default flags which includes Wall flag,
build stops because array n[3] is not initialized. Initialize it to have all
values to be zero.
"wchar_t" is usually 4 bytes big. That's not the case on Windows, where it's 2 bytes instead.
We cannot rely on that type on Linux because the target process could be native or running through Wine.
Also, it's possible that a game uses the same size for "wchar_t" on both Linux and Windows.
This commit introduces two variants of utf16ToUtf8():
1. Accepts std::u16string, for Windows processes.
2. Accepts std::u32string, for Linux processes.
The old variant, which accepted std::wstring, is removed to prevent misuses.
This commit removes all qmake-related build-files from the system. We
have now migrated to cmake and are no longer maintaining qmake anyways
and therefore there is no reason to keep it.
Removing it also clearly states to any potential user/programmer that
this project is no longer intended to be compiled with qmake.
Given that the .pri files no longer exist, the mumble-version.py script
had to be adapted to read the version from the CMakeLists.txt file
instead.
Furthermore a few of the submodules support cmake natively and therefore
we no longer need the src/buid-directory approach in order to build
them. The respective build dirs have been removed and the src-dirs have
been renamed.
