ofxNetwork: utils: remove unused WOUDBLOCK error

This error is not managed. Moreover it corresponds to EAGAIN on OSX which is
already present into the switch and leads to a build error.

invert Y texture coordinate in box primitive
log warnings when calling unimplemented ofSound functions

Closes #3412
Eliminate unnecessary destructor, copy and assignment ops in ofColor.

ofColor does not need these operations to be explicitly defined because the
compiler-supplied versions should be sufficient. Further, defining them
explicitly (and making them not inline) will hurt performance by requiring
unnecessary function calls.

Removing these also makes the class trivially copyable, which is also desirable
(it makes it possible to copy arrays of ofColor with memcpy instead of
individually copying each element, for example).
Build optimizations to reduce the size of Android shared libraries.

These changes bring the NEON androidEmptyExample library from 15.2MB down to
6.4MB. In conjunction with "ABIS_TO_COMPILE = neon", the Android APK is now
under 3MB, which significantly improves app deployment times.

This resolves issue #3416.
