PortAudio with Android Oboe support (squashed)
* Preparation to start patching - TODOS and directory src/hostapi/Oboe * Added src/hostapi/oboe/README.md * Added include/pa_oboe.h and src/hostapi/oboe/pa_oboe.cpp * Added PA_USE_OBOE section to CMakeLists.txt * Added PA_USE_OBOE section to CMakeLists.txt * Heavily reworked CMake dependencies, added FindOboe.cmake, updated pa_oboe.cpp, more work needed * Included build_all_PaOboe.sh, more work needed on CMake * Included build_all_PaOboe.sh, more work needed on CMake * Update src/hostapi/oboe/README.md * bindings/cpp: CMake: support pkgconfig with RelWithDebInfo (PortAudio#822) bindings/cpp: add `RelWithDebInfo` to the configurations allowed to install portaudiocpp.pc, otherwise you won't have support for pkg-config when building a release package with separate debugging information. Besides that, RelWithDebInfo is identical to Release. * Fix MSVC warning C4018 signed/unsigned mismatch (PortAudio#821) See PortAudio#810 * Built shared library * Polished bits * mme: don't restrict the host buffer to 16-bit Currently, the MME Host API code only creates 16-bit integer MME buffers. All audio data provided by the user is therefore converted by PortAudio to and from 16-bit, regardless of the user buffer format. This basically makes it impossible to pass 24-bit audio through the MME Host API. If the user buffer format is not 16-bit, this also causes pointless conversions to take place, *even if the hardware is running at 16-bit*, because modern Windows versions (Vista+) convert the data to floating point behind the scenes before it is handed off to the hardware. This can lead to silly situations where 32-bit float samples from the user are (lossily) converted to 16-bit by PortAudio, then ended off to Windows via MME, only to be converted back to 32-bit float again, before finally being converted to the format the hardware device is configured to use. This can easily lead to two layers of 16-bit dithering (one from PortAudio, and one from Windows) being piled on top of each other, resulting in an elevated noise floor. This commit fixes this problem by configuring the MME buffers to use the same format as the user buffer. This should stop PortAudio from converting samples in all cases except paInt8, which is not supported by WAVEFORMATEX (only paUInt8 is). This is pretty much the same idea as The new code assumes that MME will accept whatever format we throw at it. I feel confident that this is always true on Vista+ regardless of hardware, because starting from Vista MME does not access hardware directly - it always goes through the Windows Audio Engine which supports all formats in both directions (I verified this using paloopback). On pre-Vista Windows, this should still work all the way back to Windows 98 SE, because MME goes through KMixer which supports all formats [1]. Nevertheless, it's difficult to be sure, so this code checks the Windows version it's running on and preserves the old behavior (i.e. always use Int16) on pre-Vista Windows.
