Qt resources <-> std::istream interchanging

[ruslo]

Create simple example to demonstrate/PoC communication with Qt resources system and custom C++ library with std::istream interface.

Test code:

• iOS
• Android
• OSX
• Linux
• Windows

Example created: https://github.com/forexample/qt-resources-istream

Linux, OSX, Windows works ok:
build.py --toolchain ... --verbose --test --config Debug
to download Qt binaries from server on OSX use osx-10-9 toolchain:
build.py --toolchain osx-10-9 --verbose --test --config Debug

iOS works fine. If you want to download Qt binaries from server use ios-9-3-wo-armv7s toolchain:
build.py --toolchain ios-9-3-wo-armv7s --verbose --open

Android only builds, can't launch it. I think the problem is about using Qt libraries in console application. It should be either console app without Qt libraries, or GUI driven by Qt:
build.py --toolchain android-ndk-r10e-api-19-armeabi-v7a-neon --verbose.

Working with binary resources example added to branch binary.resources: https://github.com/forexample/qt-resources-istream/tree/binary.resource

Usage:

> build.py --toolchain gcc --verbose --test
> openssl sha1 gemma.png # hash of input file
SHA1(gemma.png)= 4f3615301c702a81367b8add2d4ce99d14bf2e1c
> openssl sha1 _builds/gcc/output.png # hash of output file
SHA1(_builds/gcc/output.png)= 4f3615301c702a81367b8add2d4ce99d14bf2e1c

Seems complete. Closing . Android caveat is fine for this example.
