Fix compilation issues on Windows

[ghost]

I attempted to solve compilation issues on Windows and I have revised my PRs serveral times. Hopefully this will be my last revision, maybe...

The purpose of this PR is as follows.

• Fix clang build on mingw
• Rewrite resouces files
• Fixed pointer type incompatibility warnings
• Force dynamic library named libnfc.dll and configure nfc.def when compiling
• Add missing MAX_ATR_SIZE
• Fix Conflicting macro definations in contrib/windows.h and errno.h #714

Accoring MSDN and mingw-w64, snprintf() works properly now. In #718, I took mingw-w64-crt's implementation of snprintf(), but it unchanged here.

@ikspress Hi. Do you have any build instructions for this branch? I'm pretty keen to try it out but I don't have much experience compiling in windows. Thanks for your work!

Hi. Would you mind tell me what environment you are using? MSYS2, MSVC or others?
If you want to run libnfc under MSYS2, there is already a compilation script here. Please refer to readme. If not, please tell me what you are using. If you have any trouble, feel free to tell me what you need.
