fix bugs - potential memory leak.

const std::string text = std::string((char*)ch,0,len); is using next
string constructor.
string (const string& str, size_t pos, size_t len = npos);
memory leak can occur while type converting char to string.

So we have to use next string constructor.
string (const char* s, size_t n);

Permit plugin-x plugins to ship third-party libraries.

Ignoring the libs directory's .jar files is strange. I'm not sure
whoever put the total block over libs/ knew that this is the standard
Android library directory and not just for NDK-compiled assets.

More granular ignores over libs/ contents would be better in the
future, but this fixes the odd sdk/ directory hack plugins currently
use and lets the Android build system auto-link libraries that're
shipped with plugins instead of forcing Cocos developers to manually
sift through a plugin's Android dependencies and include them by hand.
This should fix and unify finding GLFW3 for all desktop archs.
Instead of using glfw3 on each required configuration, use it centralized way.
Add our prebuilt location to search paths, so FindGLFW3.cmake can find it also.
Fix compile errors with recent mingw.

Constify arguments to copy constuctors. Without this gcc fail to compile if classes used inside containers.
Error message is rather cryptic: " error: 'constexpr std::pair<_T1, _T2>::pair(const std::pair<_T1, _T2>&) [with _T1 = const int; _T2 = cocos2d::experimental::AudioPlayer]' declared to take const reference, but implicit declaration would take non-const"
